Abstract

Abstract:- In now a day the fuel efficiency and emission gas regulation of automobiles are two important issues.To fulfil thisproblem the automobile industries are trying to make new vehicle which can provide high efficiency with lowcost.The best wayto increase the fuel efficiency is to reduce the weight of the automobile. The weight reduction can be achieved primarily by theintroduction of better material, design optimization and better manufacturing processes. The achievement of weight reductionwith adequate improvement of mechanical properties has made composite a very good replacement material for conventionalsteel. The automobile vehicle shave number of parts which can be able to replace by composite material, but due to theimprovement of mechanical properties of composite material. It has more elastic strength and high strength to weight ratio hascompared with those of steel material. So, out of many components one of the components of automobile, the leaf spring whichuse for carried out the whole weight of the vehicle is best option for replacement of steel material by composite material. Forreduce the weight of leaf spring the analysis was carried out on the model of Force Motors Trax Cruiser’s leaf spring with samedimensional geometry . The material select for leaf spring Graphite epoxy composite material and steel material we designedthe leaf spring 3d model in catia software and imported in ansys 14.5 workbench finally concluded suitable material on thesetwo materials based on stress, and the deformation , strain weight ratio
