A Review of an Experimental and Theoretical Analysis & Modification of Bajaj Discover 150cc

A suspension system or shock absorber is a mechanical device designed to smooth out or damp shock impulse, and dissipate kinetic energy. The shock absorbers duty is to absorb or dissipate energy and the helical spring is the most common element that has been used in suspension system. In this present study Non alloy steel helical spring will be used to suspend vehicle system. The uniform loading effect has been studied and Experimental, FEA analysis will be compared with analytical solution. Afterwards, the analysis will be done by considering different parameters. Experimental analysis will be done to validate the strength and modal analysis is done to determine the displacements for different loading condition. Comparison is done by changing the wire diameter of the coil spring to check the best dimension for the spring in shock absorber. Modeling and Analysis is done by using Pro/ENGINEER and ANSYS respectively.
