Design and Optimiozation of Front A – Arm Suspension System for Speciqal Purpose Electric Vehicle

Abstract

An electric vehicle also called as EV is a vehicle that make use of the electric motors for its operation. It can be operated by a set electronics system, with power from an external battery source also from the solar panels and sometimes from converting fuel to electricity using fuel cells. This project is mainly focused on the comfort and handling area of the EV’s and hence worked more on the suspension system. Suspension system is basically used to gain good road holding while driving, cornering events and sudden braking conditions and also to keep the proper steering geometry while various road conditions. Another important reason for suspension system is to offer comfort to the occupants against road shocks and provide a riding comfort. In this project, we extensively worked on the suspension system types, its design, optimization and manufacturing aspects for the initial prototype. A – Arm suspension system was selected for the study and an initial concept of the suspension system was made using Creo Parametric Software and then the optimization was performed using M.Sc Adams software for better handling behavior. Manufacturing drawing were also created for initial prototype build.
