It is observed that, in four-wheeler vehicle suspension system the helical coil spring is used, factor consider for suspension system failure are as uneven stress distribution, materials properties and manufacturing defects. If the spring failure happened, it affects the performance of vehicle which is not preferable in automobiles. The research work is focusing to find out the failure happened due to factors like dynamic and stability response, deflection of spring and so on. The research study also encourages to use of composite material like Glass fiber to improve strength, it can improve the performance to high extract. In this research work we are focusing on the conventional spring failure and on that ground optimization of existing design of spring replace by composite material. We are analyzing it by experimentation testing on UTM machine and validate by experimental on ANSYS environment putting experimental data.
