The suspension system is used to observe the vibrations from shock loads due to irregularities of the road surface. It is perform its function without impairing the stability, steering (or) general handling of the vehicle. Generally for light vehicles, coil springs are used as suspension system. A spring is an elastic object used to store mechanical energy and it can be twist, pulled (or) stretched by some force and can return to their original shape when the force is released. The main purpose of this work is to focus on the fatigue life of spring used in light vehicle suspension spring with different materials. Finite Element Analysis of spring has been carried out. In FE analysis, modeling is done in SOLIDWORK and analysis is in ANSYS. Results obtained using analytical procedures are compared with those obtained using FEA. From the ANSYS results, it is observed that the maximum deflection in the Chrome Vanadium spring is 217.47 mm and in Chrome Silicon and Hard drawn steel springs are 212.83 mm and 212.36 mm respectively. From the ANSYS results, it also seen that the shear stress in the Chrome Vanadium spring is 757.21 MPa and in Chrome Silicon and Hard drawn steel springs are 753.65 MPa and 761.32 MPa respectively . From estimation of fatigue life of Chrome Vanadium, Chrome Silicon and Hard Drawn alloy steel spring FEA approach gives fatigue life are 9x 106, 5.0108x107 and 1.484x103 cycles respectively. From ANSYS results the maximum shear stress of Chrome Silicon alloy steel spring is less and the fatigue life cycles is more when compared to the Chrome Vanadium and Hard Drawn alloy steel spring.
