Abstract
The helical compression spring used in suspension system or shock absorber is a mechanical device designed to smooth out or damp shock impulse and dissipate kinetic energy. A helical compression coil spring which used in transport three wheeler is belonging to the medium segment of the Indian automotive market. It is observed that, the vehicle drifts towards one side due to high weight of suspension system. This problem can be solved by redesigning and optimizing front suspension spring. For the present study the IS 4454 material was taken for consideration. Optimization of the spring was done by reducing total number of turns and prototypes of the spring were made. As per design the springs were made of material IS 4454 and experimental test was conducted. The static analysis using finite element method has been done in order to find out the detailed load vs defection of the spring. The experimental investigation was performed to calculate the stiffness and vertical acceleration of helical compression spring. The theoretical calculations were also done. For experimental test the universal testing machine was used to find load vs defection of spring and quarter car test rig used to find the vertical acceleration of helical compression spring.
