Devendra. K Damor, K. D Kothari

Abstract :

This project describes design and analysis of composite leaf spring made of Glass fiber reinforced polymer. The main objective is to compare the load carrying capacity, stiffness and weight savings of composite leaf spring with that of steel leaf spring. This work is carried out on a multi leaf flat spring having nine leaves used by a commercial vehicle. The finite element modeling and analysis of a multi leaf spring has been carried out. It includes two full length leaves and seven graduated length leaves. The material for the conventional leaf spring is 65si7 steel. The dimensions of an existing conventional steel leaf spring of a light commercial vehicle are taken. Same dimensions of conventional leaf spring are used to faicate a composite multi leaf spring using Glass fiber reinforced polymer (GFRP or E–Glass/Epoxy) unidirectional laminates. The FE model of the leaf spring has been generated in proe–5.0 and imported in ANSYS–11.The design constraints are stresses and deflections. A comparison of analytical, FE analysis of steel leaf spring and FE analysis of composite leaf spring results have been done to conclude.
