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.

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.
