Abstract

Abstract:- In now a day the fuel efficiency and emission gas regulation of automobiles are twoimportant issues. To fulfil this problem the automobile industries are trying to make newvehicle which can provide high efficiency with low cost. The best way to increase the fuelefficiency is to reduce the weight of the automobile. The weight reduction can be achievedprimarily by the introduction of better material, design optimization and better manufacturingprocesses. The achievement of weight reduction with adequate improvement of mechanicalproperties has made composite a very good replacement material for conventional steel.The automobile vehicles have number of parts which can be able to replace by compositematerial, but due to the improvement of mechanical properties of composite material. It hasmore elastic strength and high strength to weight ratio has compared with those of steelmaterial. So, out of many components one of the components of automobile, the leaf springwhich use for carried out the whole weight of the vehicle is best option for replacement ofsteel material by composite material. For reduce the weight of leaf spring the analysis was carried out on the model of ForceMotors Trax Cruiser’s leaf spring with same dimensional geometry . The material select for leaf spring Graphite epoxy compositematerial and steel material we designed the leaf spring 3d model in catia software and imported in ansys 14.5
