PORTFOLIO

IUT MARS ROVER

The IUT Mars Rover Team, consisting of teachers and students from IUT, aims to participate in prestigious rover challenges worldwide and foster global collaboration. As part of the team, my role was to design the frame, suspension, wheels, and wheel hubs for our rover. Additionally, I conducted FEA analysis on certain components, created renderings, and performed motion analysis.

For the frame design, I utilized the Weldments and Sheetmetal features in Solidworks. To optimize cost and weight, we opted for two shock absorbers/dampers instead of four. Moreover, we incorporated a ball joint to enhance balance while turning or traversing over uneven terrain, such as stepping on stones.

MARS ROVER WHEEL

The rover's wheel was specifically designed to leverage the benefits of additive manufacturing. It features a honeycomb structure that evenly distributes loads, allowing it to bear greater loads within the same volume. During the FEA analysis, the PA11 material was taken into consideration. The lattice structure of the wheel was optimized to enhance its performance and strength.

PROFESSIONAL EXPERIENCES

SCREW BASE PROGRESSIVE DIE

ISOMETRIC VIEW

Screw Base Progressive Die design. It should be noted that in the assembly, some simplified components were used to reduce the complexity of the fille and increase the convenience of using Solidworks.

MANUAL DIE STEPS AND PRODUCT OUTCOME

PROCESS ANALYSIS OF SHEET METAL PRODUCT

Process analyzed and designed six dies for this sheet metal products. Forming, Shearing, Punching, Hemming, Bending, all the processes were included.

SLEEVE PROGRESSIVE DIE AND PRODUCT

In the design of this die, a slider mechanism was incorporated, which proved to be quite challenging. However, the end result was a flawless product, and the process of designing this die provided me with immense satisfaction. It's worth noting that this particular die was a two-cavity die, adding an additional level of complexity to the design and manufacturing process. The successful implementation of the slider mechanism in this die was a rewarding accomplishment.

NON-PROFESSIONAL EXPERIENCES

AUDI R8

For educational purposes, a first-generation Audi R8 was designed, aiming to facilitate learning and understanding. The surface body of the car was meticulously created by tracing blueprints using Solidworks software. Subsequently, the design was rendered using KeyShot 9 to provide realistic visual representations of the vehicle.

PLASTIC CRATE

The design of a plastic crate was created using Solidworks, ensuring that manufacturability was maintained throughout the process. Careful attention was given to drafting every portion of the design, ensuring precision and accuracy in the final product.

ROBOTIC GRIPPER

SOLIDWORKS MODEL OF ROBOTIC GRIPPER

The actuator-driven Robotic Gripper was designed using Solidworks, incorporating features for both the design and FEA analysis stages. This gripper is capable of lifting weights up to 100Kg and has a 10-inch opening capacity. To ensure durability and strength, aluminum was chosen as the primary material for construction. Additionally, hardware components from the Solidworks Toolbox were utilized in the design for efficient assembly and integration.

ANSYS STRUCTURAL ANALYSIS

The gripper underwent a transient structural analysis using Ansys software. This analysis encompassed a motion study to evaluate its movement, as well as an examination of stress, strain, deformation, and the factor of safety. By conducting this analysis, a comprehensive understanding of the gripper's performance under dynamic conditions was achieved.

TOPOLOGY OPTIMIZATION

A stool was designed using the topology optimization or generative design technique. Autodesk Fusion 360's Generative Engineering feature was used for this purpose. The stool design was optimized using this technique to achieve an efficient and lightweight structure. The final design was rendered using Keyshot to provide visually appealing and realistic representations of the stool.

CPU COOLER AND 12cm COOLING FAN DESIGN

An efficient CPU Air Cooler tower was meticulously designed to prioritize efficiency and thermal performance. Solidworks was utilized for the design process, while KeyShot was used for rendering. The cooler features a double fan setup in a "push-pull" configuration, enhancing its overall performance. To facilitate faster heat dissipation, eight copper heat pipes and numerous aluminum blades were incorporated into the design. The CPU cooler also includes a 120mm cooling fan with efficient casing, designed to minimize noise by optimizing airflow with low RPM. The configuration of the blades enables the movement of air at a faster rate, further contributing to noise reduction.

DRILL JIG

This project was a part of the course "Tool Engineering." The objective was to design a drill jig whose purpose is to perform drilling operations without shifting the job regularly. The analysis work is carried out on clamp plates to determine the stress, strain, and deformation using ANSYS. According to the dimension, all parts were designed and assembled by using SolidWorks to test its performance.
