In this study, a helical spring which is used in two wheeler and three wheeler front suspension system was taken in to consideration for optimizing coil size and shape. The existing problem is observed that, the vehicle drifts towards one side due to heavy weight and poor performance of the helical spring. This problem can be rectified by optimizing the size and shape of the coil spring. For optimizing, the existing model of solid circular coil with straight profile spring were compared with solid elliptical model springs. The stiffness, stress and deflection were calculated using numerically and verified with analytically, moreover the shape factor for efficiency was verified numerically. The analytical results were obtained using FEA code Ansys15.0 software. Finally, it was concluded that the elliptical coil spring exhibits better shape factor for efficiency, high stiffness with occupying less amount of space, very low stress and deflection when compared to existing model spring .
