Nowadays, transportation industry plays major role in the economy of modern developing andrnindustrialized countries. Weight reduction is now the main issue in automobile industries. Thernchassis frame is an important part in automobiles. The main function of the automobile chassis isrnto carry the goods and payload placed upon it. So it must be strong enough to resist the shock,rntwist, vibration and other stresses. In the present work, the dimensions of an existing lightrnvehicle chassis of a TOYOTA(LJ150-GKMEE) vehicle is taken for modelling and analysis of arnvehicle chassis with composite materials namely S-GLASS epoxy and HSLA Steel, subjected tornthe same load as that of a steel chassis. Reduction of weight of various parts of a vehicle canrnimprove the performance and efficiency of the automobile. The composite materials provide arngood strength-to-weight ratio, which could be replaced for the conventional materials. This paperrndeals with the structural analysis of a frontend cross bar which is replaced with s-glass FiberrnReinforced Polymer composite material. Maximum stress and maximum deflection are importantrncriteria for design of the chassis. The objective of present is to determine the maximum stress,rnmaximum deflection. For validation the design is done by applying the vertical loads actingrnhorizontally in the existing cross sections. To do this research I use The FE analysis for a lightrnmodeling by utilizing commercial finite element analysis software packages like CATIA andrnANSYS. Then I contribute light and high strength chassis for light and green vehicle.
