Abstract— The present work is focused to improve the vehicle stability by Split type suspension system. It is very difficult to obtain maximum isolation of body weight from vibration in ordinary suspension system.So identify the actual problems in existing system and analyzing to solve the problems in split type suspension system.Among the two springs in Split type suspension system one has more stiffness for providing better shock absorbing capacity. The split type suspension system is tested under various considerations. The deflection of the proposed system is tested in universal testing machine and also the variation of dynamic response of the spring is known through the shock analyser test rig. Finally, the experimental and theoretical calculations for load distribution, natural frequency, damping coefficient are evaluated and compared for both existing and proposed system.
