Modelling of Blasts and its Effects
Modelling of blasts (explosions) in air involves prediction of the change in pressure with time. A number of equations have been proposed by different researchers for this purpose. The different variables of these equations are, in turn, related to other parameters like the scaled distance by more relationships. The first part of this work analyzes all the available relationships available in literature and suggests a conservative set of relationships - those which are less likely to over-predict or under-predict the pressure variation of an air blast. In the second part of this work, three air blast experiments reported by different authors on different steel alloys have been modeled by finite elements. The parameters of a Johnson Cook material model which will give the best prediction for maximum deflection after blast for all of them was obtained through complex search method. This gave a basis for choosing a first cut assumption for the material model for steel alloys commonly used in blast resistant structures. This would be useful in cases where detailed material properties is not available before the experiment is conducted.
Active suspension controller and test rig design for quarter car model

Path planning for mobile robots using Biased A Star algorithm
This work focuses on modification of the A star path planning algorithm. The problem of path planning in a two dimensional space was explored where the robot has limited information in two aspects, namely a limited range of visibility and coordinates of a region where the target position is speculated to be. The objective is to ensure that the robot explores as little of the map as possible before arriving at its target destination. A thorough literature review was conducted on the current path planning algorithms and the A star algorithm was chosen for modification given its ease of manipulation and its scope for improvement with respect to the project objective. The new algorithm, the Biased A star algorithm, introduces a variable bias in the behaviour of the robot which causes it to favour certain paths over others and curtail unnecessary map exploration. Special attention is given to the biasing scheme which changes the bias as the robot journeys from outside the probable target region to inside of it. The changes in the advantage provided by the new algorithm have been studied by changing various parameters like obstacle type, obstacle density, visibility range of robot, size of probable target region and the start position of the robot. The results have been reported after implementing the Biased A star algorithm in MATLAB. It was found that the primary advantage of the Biased A star algorithm lies outside the probable target region. Further, possible future work using strategies of more flexible movement, obstacle avoidance, nested A star and multiple biasing have been proposed.
Design optimization of tethered aerostats for solar photovoltaic power generation
A method of obtaining the dynamic characteristics of an aerostat of arbitrary (non-standard) shape was obtained. The method involved novel use of computational fluid dynamics (CFD) software and discretized time domains. The results were validated against analytical results obtained for aerostats of standard design. This method is now being used for generating a range of displacement and orientation profiles of aerostats and predicting the power output from on-board photovoltaic panels of various configurations.
Vibration based health monitoring of honeycomb core sandwich panels using support vector machine
Composite structures offer a significant advantage in terms of specific stiffness and specific strength. Thus they have received a significant attention mainly in the aerospace and space industry. Barely visible impact damage occurs in composite structures even from low impact damage which can result into catastrophic failure. Composite materials mainly fail due to matrix cracking, fiber failure, fiber debonding and delamination. Out of these four, delamination is most important one as it causes significant structural damage particularly in compression and needs to be checked at an earlier stage. Honeycomb core sandwich panels are one of such composites. Honeycomb sandwich panels are made by adhering two high rigidity thin sheets with low density honeycomb core. The common damage in these composites is debonding which is equivalent to delamination. The current work presents a new array based technique for health monitoring of the structure using Support vector machine (SVM) classification. This is a model based technique wherein a FEM based baseline structure is used. The structure is divided into rectangular zones assigning horizontal and vertical classes to structure. Each zone can be located by unique combination of a horizontal and vertical class. Initially the technique is qualified with an aluminum plate and then the same technique is extended for honeycomb core sandwich structure using mode shape data. The analysis is carried out by changing the number of classes and by changing the distribution of training damage locations. SVM predicts the horizontal and vertical class for the test dataset through which the damage location is identified. The technique is tested with noisy data from simulation and experimental vibration data. Eight samples of honeycomb core sandwich panels and aluminum plates are fabricated for generating first mode shape displacements data. A comparison between SVM classification and SVM regression is also presented. The proposed technique is able to locate the damage efficiently with an error of nearly twenty percent with noisy and experimental data. The proposed technique has been used for damage intensity measurement in a slightly modified form. The results are excellent even in presence of noise. It turns out that SVM classification is performing better than SVM regression in the presence of noise and experimental vibration data.
Design optimization and motion dynamics of mobility system for mars rover
Planetary exploration rovers offer promising alternatives for conducting in-situ experiments on earth's neighbour planet -Mars. Several configurations have been suggested for the mobility system of such rovers, some of which have been successfully tested in past missions or are being implemented in the upcoming missions. Considering the huge costs of such exploration missions, it becomes necessary to design an optimal mobility system configuration to meet the mission goals. Furthermore given the costs and efforts of building test-beds for evaluating the performance of mobility system and on-board control software, it is also important to develop simulation tools to serve the purpose. The first half of this thesis focuses on obtaining an optimal design configuration of mobility system for mars rover. Various configurations of suspension systems were studied and certain performance metrics were devised to compare their performance. After the preliminary analysis, six-wheel rocker bogie suspension was determined to be most suitable amongst the evaluated configurations. Two performance metrics were considered in the objective function for design optimization viz. Power Consumption and Effective Ground Pressure. Geometric trafficability and load equalization conditions were evaluated to obtain the constraints on design parameters. Analytical expression for driving power was obtained using an established wheel-soil interaction model. The second half of this thesis focuses on development of a motion dynamics simulation model for the rocker-bogie suspension system. More recently, researchers have proposed the idea of using reconfigurable wheels, which would be able to change their shape according to the terrain, to improve rover's performance. One of the major challenges in implementation of such wheels is their control and autonomy. To avoid complex on-board calculations, the method of using look-up table for autonomously changing the wheel dimensions is proposed in this thesis. For obtaining this look-up table, a physics based motion dynamics simulation model was developed, incorporating the wheel-soil contact mechanics, drive motor characteristics and motion dynamics of the rocker bogie suspension system. This model was implemented in MATLAB and the simulated motion of rocker bogie system was shown for some test cases. This simulated motion of rocker bogie was found to be in conformance with the ground profile. Another important performance metric called as 'Slip Ratio' was evaluated through the motion simulations. Finally, a lookup table for autonomous shape changing wheels was developed for certain terrain characteristics.
Path planning of mobile robots using Support Vector Machine
The ability of an autonomous mobile robot to navigate a known environment depends, among other factors, on the quality of the path. A good path is close to the shortest one has low number of sharp turns. Current research has mainly addressed the ability to find the shortest path and the time required for it. The smoothness of a path has been largely ignored. In this work, a comparison was made of the known approaches for finding the shortest path e.g. A* and artificial potential field. Based on these results, A* was used for obtaining the shortest path and then Support Vector Machine was used for smoothening that path. An algorithm was also proposed for obtaining a quantitative measure of the overall smoothness of the path and was used to evaluate the effectiveness of the path planning algorithm for different scenarios. These involved the robot’s navigation through closed environments with randomly placed obstacles.
Finite element modelling of low stress mechanical properties of fabrics
Fabrics are subjected to low stresses i.e. stresses much lower than breaking stresses during their normal usage. These stresses are often in-plane but not directed along the yarns. This gives rise to fabric shear and causes structural changes to the fabric e.g. the pore size (minimum distance between yarns), which in turn affect many other fabric properties. A number of fabric modelling methods have been proposed to predict the structural changes in the fabric due to low in-plane stresses. Micro scale fibre models can be used to build up the yarns and then the fabrics but they are extremely computationally intensive. Macro scale fabric models can be used in which the properties of a small patch of fabric (the unit cell) are assumed to be known and are then duplicated over the entire fabric. These will not be able to predict the pore size changes because that is a property of the unit cell. Meso scale models assume yarns to be continuous flexible cylindrical structures which are intermingled to form a fabric. These can be used to predict the structural changes of a fabric within a reasonable computational framework. Among the different meso-scale modelling techniques, finite element based approaches often assume a known shape and configuration of the yarn in the fabric as the initial condition and thus ignore the residual stress in the yarns. This work used a two-step finite element modelling procedure. The first step involved simulating the woven fabric formation procedure which ensured some residual internal stresses in the yarns in the fabric. The orientation of yarns was allowed to evolve rather than being pre-defined. In the second step, this structure was subjected to shear. The displacement of the edges of the fabric were duplicated in a picture frame experiment in which the four sides of the fabric were attached to a square frame and then the frame was converted into a rhombus in a universal tester. The in-plane fabric stress (as given by the universal tester) at different shear angles (measured from the fabric with a microscope) was compared with the stress predicted by the finite element model. Different material models were compared and a particular combination of anisotropic yarn property was found to give a very good match with experimental results.
Structural health monitoring of a composite plate using support vector machine
This work explored the possibility of predicting the location of delamination in a simulated composite plate from only the knowledge of the natural frequencies. An eight layer circular composite plate fixed at the edge was simulated in a finite element software (Abaqus). Delamination was simulated between the fourth and fifth layers and its location was varied from the centre to the edge. The size of the delamination was chosen based on a study of the effect of delamination on the first four natural frequencies. An inspection of the mode shapes showed a similarity in the 1st, 6th, 17th, 30th, and 51st. These were symmetrical about the axis of the plate and the intermediate ones were not. This inspired a study to be conducted to check the capability of the first 5, 16, 29 and 50 natural frequencies for predicting the location of delamination using support vector machine. An improvement of prediction error from 33% to 16% was observed with the use of higher number of natural frequencies.
Fabric waste minimization in garment cutting using evolutionary programming
This proposes an Evolutionary Programming approach for the optimization of cutting operation in the apparel industry to maximize the cloth utilization. Fabric cutting is a typical strip-packing problem with n polygon pieces to be fit in a rectangular cloth of fixed width such that height is minimized. It is a considered to be an NP-hard problem and thus, optimality cannot be claimed by any approach. The proposed approach is expected to be superior to others in terms of its ability to handle complex geometries. This has been done by applying the no-fit polygon approach and allowing 90 and 180 degrees rotation to selected pieces and has been demonstrated for both convex and concave geometries. The evolutionary programming approach provides an improvement over other approaches because of its inherent feature of parallel search and the ability to get out of local minima/maxima though the process of mutation.
Estimation of power for a shuttle loom
The primary motions of a textile loom are interconnected and are driven by many reciprocating parts. The power required by each motion is cyclic in nature with the peak power requirement for each motion occurring at separate times. Thus, the mechanism draws and gives back power at different times in the loom cycle. In this work, a set of equations have been formulated to model this phenomenon with the aim of estimating the total power requirement of a loom from the masses of all the elements. This allows the effect of change of mass in any element on the total power requirement to be predicted and is expected to aid a loom designer.
Design of manually operated peanut decortication, dehusking and separation machines
Medicated peanut paste has been identified as a Ready-to-Use Therapeutic Food in rural areas. Peanut decortication (removal of the hard outer shell), dehusking (removal of the thin inner cover) and separation of the outer shells and thin inner covers from peanuts are three operations which are either done manually or need large machines with high power consumption. This work has explored a large number of options and has suggested a design for each of these three operations. All of these can be manually operated, thus avoiding the vagrancies of power supplies in rural areas. The prototypes were manufactured and tested with different types of peanuts and optimum working modes were identified.
Topology and size optimization for FEA based impact simulations
Minimization of mass of a structure being subjected to impact loading can be done by either topology or size or shape optimization in Optistruct. This work explored the different options available under topology and size optimizations under the constraints of stress and internal energy. Adaptive response surface method was tried and mass reduction varying from 10 to 60% was achieved.
Parameters affecting FEA based impact simulation
An impact simulation using finite element analysis will give close match with experiments only if the parameters used for simulation are set correctly. The objective of this project was to determine of effect of various parameters on results obtained from non-linear dynamic analysis of impact simulation for a cylindrical projectile. Abaqus/Explicit and Abaqus/Standard, the explicit and implicit solvers of ABAQUS were used. The implicit scheme showed a drop in total energy of the system at the instant of impact. A detailed study of this phenomenon failed to elucidate its reason or a way to reduce it. The explicit scheme, which did not show any such discrepancy, was used for the rest of the study. The results (Lf/Lo ratio) were found to be highly sensitive to material density and yield stress. Dilational wave speed had a moderate effect while Young’s modulus and Poisson’s ratio were found to have a negligible effect. The deformed shape of the cylinder after a Taylor impact test was found to differ from experimental results but there was a very good match with the Lf/Lo ratio.
Study of four-wheel independent steer-by-wire system to enhance vehicle stability and handling
In a four wheel independent steer-by-wire system, all the four wheels of a vehicle can be steered independently by actuators responding to computer generated signals. These have a distinct advantage over the other steering systems as control is available over the individual slip angles of the vehicle in steady state conditions. This work proposed a method of handling vehicle performance in both high speed and low speed regimes. Simulations show a significant increase in maximum cornering speed at all turning radii. This also includes some low speed turns a conventional front wheel steered vehicle cannot make. The potential cornering speed increase is of 10-20% during off-limit cornering and as high as 40% during on-limit cornering. The system is also successful in decreasing the average slip angle during cornering by 10%. This not only improves tyre life but also reduces rolling resistance. The percentage utilization of the tyres can attain values of upto 95% as compared to a maximum of 83% in case of conventional steering systems. This allows the maximum cornering speed to improve by 43%.
Simulation of fibre and its interaction with machines
Modeling and simulation of fibres has been attempted with the aim of predicting the interaction of fibres amongst themselves as well as machine parts. Principles of molecular dynamics have been employed to simulate large aspect ratios. The results are promising and a framework for such simulations has been suggested.
Modeling of lower human limbs for Indian population
Cross legged sitting posture is very common in Asian cultures. But there are few studies to model the motion of standing up from this posture. This study reports a mathematical model for predicting joints moment during this action. Quasi-static analysis (speed of rising is slow, so accelerations of limbs are assumed to be zero) was done here. Joint angles and ground reaction forces were taken as input parameters. Maximum knee, ankle and hip joint moments during standing up from cross legged sitting posture were found to be close to the moments generated during the motions of squat to stand or standing up from chair. However, high moments occur during internal rotation and abduction at hip joint. This leads to stresses at separate regions of joints and activation of different muscle groups compared to what is observed during squat to stand and sit (on chair) to stand motion.
Modeling of a tether for aerostats
The tether for an aerostat has a core of parallel strands and a sheath of braided or twisted fibres. This undergoes cyclic loading during repeated tests on an aerostat. Modeling of the tether for the purpose of predicting its life was attempted in this work. A damage index for predicting the reduction in strength of the components after cyclic loading was experimentally determined. A spring-damper based core-sheath structure was used for modeling the tether which could predict the trend of change in strength correctly.
Study of explosion of internally pressurized pipes
Explosion of internally pressurized buried pipe can be stimulated both physically and numerically. In this work, an attempt was made to provide guidelines and parameters for the design of underground pipes to resist the effects of explosion. Numerical simulation was carried out by using FLAC2D (Fast Lagrangian Analysis of Continua in 2 dimensions, Itasca 2006) which is based on finite difference method for advanced 2D geotechnical analysis of soil and rock. Principal stresses, principal strains and maximum displacements developed in the model at different locations in pipe were observed. The effect of different parameters on resistance of pipe to the explosion was studied. An experimental explosion triggering arrangement was developed to physically simulate internal explosion of buried pipe. Normal and high gravity tests by using centrifuge were carried to understand the deformation behavior of embedded pipes and consequences of their explosion.
Development of saree cutting machine for visually impaired people
An NGO in Latur district of Maharashtra has established a handloom weaving cum training and production center situated at village Budhoda. This centre encourages visually impaired people to produce mattresses by cutting old saris to the size of ribbons and using these ribbons as weft on handlooms for making mattresses. This work aimed at developing manually operated devices for cutting saris into multiple ribbons. Prototypes of two such devices were demonstrated.
Predicting hygrothermal stresses in woven fabric composites
Prediction of internal stresses in composites due to changes in moisture and temperature can allow better prediction of overall structural failure. This work establishes a method of modeling woven fabric composites using classical laminate theory which allows internal hogrothermal stresses to be predicted from a knowledge of mechanical properties of the fibres and resins. It was applied on cross ply symmetric and unsymmetric laminates.
Development of a multiple ball dropping mechanism in high gravity environment
The objective of this study was to custom design, fabricate and calibrate multiple ball dropping mechanism for simulating vibrations of a moving train in high gravity environment. This instrument can simulate both impact point load and also moving load conditions caused by high speed trains passing through the viaducts. The movement of train was idealized as a set of impact loads dropping with some time interval. The load impacts a strain gage based load cell which measures the impact energy. The load cell was designed based on Morehouse proving ring concept and calibrated. The propagation of the ground waves was recorded using accelerometers. The variation of impact energy with speed was investigated. The time delay in the ball drop was provided using a shaft having stoppers at different angles for energy simulation and having the load cells at different heights and keeping the stoppers at same angle for speed simulation. The instrumented simulated high energy during the tests, which gave the feel of stresses coming on the real structures. The result showed that the impact energy coming on the bridge pier is independent of the train velocity, hence in experiments can be decoupled and analyzed. The acceleration data shows considerable reduction in the acceleration as we move away from the impact point and also gives the spread of vibrations in the ground. The results from the tests show that the proving ring concept load cell can be used to measure the impact loads with good repeatability. This report presents design details and experimental observations of energy and vibrations of the proposed multiple ball dropping mechanism along with the design calculations.
Design and fabrication of in-flight sand hopper
The objective of the study was to design and develop In-flight sand hopper for simulating construction process of embankment construction on soft ground. For this purpose, a sand-hopper compatible with existing plane strain container at centrifuge laboratory was custom designed and developed. Various components involved in this hopper were designed for their adequacy at 50 gravities. In order to calibrate the system, several tests were done at normal gravity and some selected tests were done at 50g. Directional vanes were kept at 40 degrees to the vertical to nullify the coriolis effect. However, results showed that this produces heap like embankments. This was corrected to some extent by changing the direction of fall of sand during flight. Further trials are warranted to fine tune the embankment construction process during centrifuge tests .The system can be used to simulate construction of iron ore heaps, and embankments on soft ground.
Determination of aerostat shape
The problem of prediction of deformation of the surface of an aerostat can be considered a part of the larger problem of predicting the deformation of a membrane under pressure. The majority of literature available has concentrated on predicting only the maximum deflection and not the complete shape of the deformed membrane. In this work, a 2D model for predicting the complete deformed shape of a circular membrane has been extended to predicting the deformed shape of an arbitrarily shaped membrane. In the process, the membrane deflections in a 3D space have been computed. Comparison of the results with experiments and those predicted by Finite Element Analysis indicates the scope of development of better models for predicting the shape of a deformed membrane.
Simulation of displacement and orientation of an aerostat
Mechanism simulators like ADAMS allow displacement of a rigid body to be predicted from a prior knowledge of forces acting on it. CFD allows force on a rigid body to be predicted from knowledge of the nature of fluids flowing past it. However, in real life, the force on the rigid body causes a change in its displacement and orientation which in turn affects the force itself. This two way fluid-structure coupling has been attempted in this work using a dynamic mesh. Numerical experiments using rigid bodies of different shapes and fluids of different Reynolds number gave encouraging results.
Optimal loading of boxes into multiple containers
Container loading problems have been studied extensively in the literature and various analytical, heuristic and meta-heuristic methods have been proposed. In this thesis, we present four different variants of a genetic algorithm framework for the three-dimensional container loading problem (3-D CLP) of optimally loading boxes into multiple containers with constraints. The algorithms are designed so as to incorporate various packing constraints found in real life problems. The algorithms are tested on data of standard test cases from literature. The algorithms developed not only compare well with the benchmark algorithms from literature in terms of utilization of containers for standard test cases, but they also have an advantage of implementing a range of practical constraints which cannot be found in other algorithms reported in literature. This greatly improves the effectiveness of the algorithm in solving real life problems which is demonstrated by solving a real industrial problem.
Looms for 3D fabrics
Mechanisms have been designed which will allow both interlaced and non-interlaced (noobed) 3D fabrics to be created in the same machine. A few additional elements allow biased yarns to be inserted. The designs are in the process of being patented.
Fault Detection in Yarns by Image Analysis
The capacitance based yarn fault detection used by the industry allows fault detection at very high speeds but does not allow any feature of the fault except length and diameter to be measured. Image analysis based yarn fault detection offers the possibility of feature/shape based classification of faults and may also lead to machine defect based classification of faults. Deliberately generated faults in a ring frame were analysed with image analysis techniques and classified with artificial neural networks - both feedforward and Kohonen. The optimum magnification was identified and an accuracy of 70% to 100% was achieved. Shape context based classification techniques were also investigated. The classification was not as good as with feedforward neural networks but it allows rotation and magnification independence.
Optimization of surgical rod cutter
Titanium rods used as spinal implants need to be cut to a suitable length in the operating room. The mechanism used to cut them needs to be entirely manually operated since the interference of electrical and electronic components with the sensitive electronic components cannot be predicted. The mechanism also needs to be as small as possible since it needs to be decontaminated in an autoclave prior to its use. This work explores different options for such a mechanism. In the first part of this work, the best design from a scarce patent literature was optimized to obtain a 56% reduction in dimension. The manual force was verified with a mechanism simulator (ADAMS). A material model in DEFORM allowed the experimentally determined shearing force to be simulated. This led to the prediction of change in the mechanism’s dimensions with change in the rod’s dimensions. In the second part of this work, a hitherto unreported design which allowed torsional shearing, was subjected to a similar optimization exercise. The final mechanism was of half the size as that of the previous mechanism.
Kinematic evaluation of four bar models of human knee
The four bar linkage has been suggested as a knee prosthesis in recent years. Studies on the knee mechanism are dominated by stress analysis of different components of knee mechanisms. Optimization of the mechanism from the point of view of its kinematic properties has been attempted to a lesser extent. This work identifies a few kinematic parameters which can be used to evaluate its performance. It then combines them into a single objective function and uses it to evaluate different four bar mechanisms. The method described here can be used to both optimize and evaluate existing four bar knee mechanisms.
Optimizing aids for paraplegics
Aids for paraplegic patients allow them to stand from a sitting position with lower effort than what would be otherwise required. A large number of designs for such aids were proposed in an earlier work. These designs were evaluated in this work for the knee torque required. Three design parameters were varied and force needed to be exerted by hand on a cane was considered as a constraint. The best design was identified and optimized. The optimized mechanism resulted in reduction of knee torque to one-third of its original value.
Fast Non-Invasive Methods for Yarn Cross Section Imaging
Visualisation of the cross section of a yarn by traditional methods requires 24 to 48 hours of sample preparation. Absence of a faster method has precluded its use as a quality control measure. In this work, two attempts to obtain the cross sectional view of a yarn has been reported – one based on optical coherence tomography and the other based on confocal microscopy. Limited success has been reported for both attempts.
Optimum Packaging of Stenter
The large size of the stenter requires individual components to be transported from the manufacturer to the user in multiple containers. A study of this topic revealed that the more general “container loading problem” needs to be solved for improving stenter packaging. This has also been described in literature as “Packing of small boxes in large boxes.” A search of container loading problems reported in literature led to the identification of two promising approaches. These two approaches were evaluated on a number of simulated packaging problems. The better amongst the two was identified. This was further modified by simplification of the solution procedure and addition of other constraints. Evaluation of all the methods revealed the superiority of the method developed in this work particularly in terms of time taken to solve problems involving large number of constraints. This is expected to lead to better algorithms for solving the “multi-container loading problem” which will allow the stenter packaging problem to be addressed.
Modification of Cotton Flyer
This study was undertaken to explore the possibility of reduction of material used for manufacture of the cotton flyer while keeping the flyer leg deflection due to centrifugal forces within acceptable levels. Simulation of different designs with the aid of finite element analysis indicated the possibility of 20% reduction without significant ill effects. Increase in air resistance in some of the proposed designs was estimated with the help of computational fluid dynamics. The corresponding increase in total power requirement of the speedframe was estimated to be well within acceptable limits.
Energy Optimization of Stenter
The mass and energy flows through a stenter were modeled. A scheme for operating the primary change points of a stenter which minimizes energy consumption was suggested.
Novel Design of a Positive Rapier Head
Positive rapier heads can give higher weft transfer efficiency compared to negative rapier heads. However, they may cause damage to warp yarns and have a lower working life because of repeated impact between cam and follower. This work suggests an alternative design in which these deficiencies are removed. A model of the mechanism was made and run at speeds close to loom speeds. Analysis of clamp openings with high speed photography seems to suggest that the proposed design will be easier to work with at high speeds than at low speeds.
A Device for Saving Energy of Shuttle Picking
A magnet based device for saving energy of picking the shuttle of a loom has been investigated. Experiments on a shuttle like device indicated the possibility of 50% energy saving. The use of solenoids for energy regeneration has also been investigated.
Reducing Energy Required for Running a Loom
As the speed of a loom increases, the power requirement goes up due to losses in deceleration of oscillating links. This power loss is directly proportional to the cube of the operating speed. The current project established the theoretical basis of saving this power in rapier looms with use of springs and inertial elements. The method was demonstrated with simulations.
Warp Breakage Detection Mechanism
A wide range of options were explored for designing a warp breakage detection mechanism which would have some advantage over the drop-wire based system. An image analysis based system was demonstrated on a set of parallel threads which was assumed to simulate a warp sheet. The accompanying algorithm was also developed.
Design of a Novel Drive for Rapiers
Most of the current mechanisms used to drive rapiers use prismatic pairs or a rack and pinion mechanism, none of which are suitable for high speed operation. The current project explored different design solutions which can eliminate these problems. The best possible straight line approximation of the coupler curve of a crank rocker mechanism was obtained and was suggested as a rapier drive.
Modelling Yarn Balloon During Ring Spinning
In this project, the image of a yarn as it forms a balloon during ring spinning was captured. This was used to validate the currently accepted models of yarn balloon using a new procedure. The effect of changing the spinning parameters on yarn balloon was also observed. This may lead to a better way of positioning the balloon control ring.
Design of a Yarn Hairiness Tester Working on the Principle of Image Analysis
The current generation of yarn hairiness testers aim to conduct the test at higher and higher speeds. As a result, the hairs have to be detected by indirect methods and some information about hairiness is lost. The aim of this work was to explore advance techniques of Digital Image Processing (DIP) for hairiness measurement to extract all possible information about hairiness from static yarn images. Various issues related to hairiness measurement with reference to DIP such as selection of appropriate optics, mathematical formulation, and use of appropriate DIP tools were analysed. Existing hairiness measurement techniques and their drawbacks were also studied. The possibility of capturing images of moving yarn and extracting complete information about hairiness was explored. Improvement in hardware necessary for image capturing is likely to make this technique viable in future.
Development of Novel Mechanisms for Dobby
A mechanism has been designed to provide dwells to the knives of a dobby at their extreme positions without using cams. This will allow the maximum shed depth to be reduced, leading to less strain on warp sheets compared to current linkage driven dobbies.
Programmable Ring Traversing Device for Ring Spinning
Raising and lowering of the ring rail of a ring frame is usually done with a cam. This precludes the possibility of changing the building mechanism in a ring frame. A microprocessor based programmable traversing system was designed and fabricated. The capability of the system to perform for an extended period was demonstrated by building full cops. This will give the spinner the option of changing the build from cop build to roving or combination build.
Design and Fabrication of a Machine for Making Prefabricated Vertical Drains
The most widely used prefabricated vertical drains (PVDs) use a corrugated (or suitably shaped) polymer sheet as the core and nonwoven material as sheath. Both of these are manufactured in India. But there is no company in India which combines these to make the PVD. As a result, the PVDs, which are being used in increasing numbers, have to be imported at a very high cost. Such a machine was designed and fabricated under this project.
Automatic Doffing of a Cloth Roller on a Loom
A hand operated wheel mounted device was designed for loom auto-doffing. All the operations, disengaging the cloth roller from the loom, removing it from the loom, loading an empty cloth roller and carrying away the full cloth roller can be done by a single operator by operating the mechanism manually. Three different designs were studied. The final design was can pass through narrow aisles between rows of looms.
Study of Existing Sley Drive and Development of Novel Devices
A linkage based mechanism which will give a dwell to the sley near its backmost position was designed. This is expected to be cheaper to incorporate into a loom compared to cam based sley drives. It will give lower abrasion between warp threads and shuttle during weaving.
Automation in Garment Cutting
This project, apart from automation of the cutting process, investigated an alternative cutting tool for fabrics namely laser. Software has been developed which takes the essential dimensions to generate a shirt as input and gives the CNC code to cut the pieces in a particular fashion, to minimize waste under the given constraints, as the output. A design has also been proposed for an automatic laser cloth cutter which read the CNC code generated by the software and cut the fabric in that fashion using laser as the cutting tool.
Core yarn attachment for ring frames
An attachment for spinning core yarn was retrofitted on an LMW G5/1 ring frame. A yarn tension measuring device was designed to continuously monitor the tension in the core yarn. Effect of different factors including tension and manner of feeding on the quality of core yarn was studied.
