Analysis of Coil Spring Used in Shock Absorber using CAE

Vehicle suspension system has to perform complexity requirements, which includes road holding and equality, driving pleasure, riding comfort to occupant. The objective of this paper is to analyze the performance of Shock absorber spring by varying stiffness, which is obtained by doing optimization using Genetic Algorithm as optimization tool to obtain maximum ride comfort. The Shock absorber is one of the suspension systems designed mechanically to handle shock impulse and dissipate kinetic energy. It reduces the amplitude of disturbances leading to increase in comfort and improved ride quality. The spring is compressed quickly when the wheel strikes the bump. The compressed spring rebound to its normal dimension or normal loaded length which causes the body to lift. The spring goes down below its normal height when the weight of the vehicle pushes the spring down, spring resist deformation. Modeling and analysis is done using Pro E and ANSYS respectively.
