Abstract. This study aims at designing and analysis of roll cage for an electric solar vehicle fabricated for Imperial Society for Innovative Engineers ESVC (Electric Solar Vehicle Competition) 2019. The vehicle will be powered by electric motor and charging will be done by solar panels which makes the design eco-friendly. This study focuses on the development of an optimized roll cage structure which will include the compactness of frame design, light weight and driver’s safety considering all the design ergonomics and the driver’s safety measures. Optimization is based on reducing weight, strength considerations and ergonomics consideration. Variation of materials, pipe diameters and 3-D structure is implemented during analysis. Analysis of roll cage is conducted using SolidWorks and loading conditions are taken as per standards. Three-wheel tadpole configuration is used for analysis purpose. Results are presented in form of graphs and SolidWorks analysis outputs. 

Abstract. Suspension system serves purpose of providing stability to vehicle which results improving comfortability of riding. It provides traction control and steering stability. This paper proposes a method for designing double wishbone suspension system for electric solar vehicle with damper to lower wishbone. Recent trends in suspension system have focused on improving innovations in ride quality and handling of vehicles. It maintains a viable spectrum of economic growth by reducing costs and increasing efficiency simultaneously. Theoretical analysis is conducted using Lotus and Solid works to design double wishbone suspension system. The analysis is done for tadpole geometry car with double wishbone in front and swing arm in the rear wheels. Results in the paper are going to improve vehicle handling characteristics by controlling camber, toe angles and A-arm's length. This is accomplished by changing the length of A-arm and the ground clearance and attach angle with the chassis by hit and trial method and improving possible traction and maneuverability. Results of the paper are presented in form of graph as a result of simulation conducted. 

Abstract. Suspension geometry plays a major role in the static and dynamic stability of the vehicle. A proper suspension geometry helps in vehicle maneuverability at different roads and sharp corners. This chapter deals with the designing of suspension geometry of a three-wheeled vehicle with tadpole configuration with double wishbone suspension geometry at the front of the vehicle and swing arm suspension geometry at the rear of the vehicle. The main purpose of designing the suspension geometry at the front of vehicle on LOTUS is to control the camber and toe variation in the wheel at various dynamic and static condition. 

Abstract. Wind energy is a renewable source of energy besides being a clean source of energy. At a time when conservation of resources is the need of the hour, the better utilization of the present reusable sources should be the utmost priority. One of them being the wind turbines. A wind turbine is a device, which converts the energy of wind into mechanical energy, and this mechanical energy with the help of a generator is converted into electrical energy. The conservation of energy is at the top for a sustainable and quality environment and wind energy is one of the few yet best renewable resources. The vast potential of wind energy has never been in doubt however, access to abundance has always been a challenge. This paper covers the possibility of enhancing the existing methods of power transmissions and thereby the better efficient performance of the wind turbine The present electrical methods to cover for the variation in speed of the wind and variable input to the generator is doing a good job but this paper encroaches the mechanical aspect of the system something which has not been looked at while this time. The arrival of Continuously Variable Transmission (CVT) in the automobile industry was a breakthrough in automatic power transmission. We credit our inspiration and approach the CVT only, the ability to provide optimal gear ratio in varying conditions is what we engulfed upon. We are proposing the design of a system based on CVT to provide the solution to the varying input problem to the generator.
