This dissertation work deals with the elaborate design optimization technique for truck chassis with FEA method. Chassis is one of the important parts that used in automobile industry. It is a rigid structure that forms a skeleton to hold all the major parts together. Chassis frames are made of “steel section” so that they are strong enough to withstand the load and shock. Chassis must be light in weight to reduce dead weight on the vehicles. Major challenge in today’s automobile vehicle industry is to overcome the increasing demands for higher performance, lower weight in order to satisfy fuel economy requirements, and longer life of components, all this at a reasonable cost and in a short period of time. The study is to produce results to rectify problems associated with structures of a commercial vehicle such as strength, stiffness and fatigue properties along with stress, bending moment and vibrations Iterative FEA approach for selection of different loading conditions as given above on truck chassis and optimizing through selection of different cross section suitable to withstand loads with maximum factor of safety, like I or C or sq. section profile and thus ensuring weight reduction without compromising in mechanical strength by topology optimization.

After manufacturing of truck chassis, analytical results are validated experimentally by stress analysis of truck chassis with the help of universal testing machine (UTM). The process of validation for this method is Followed by fabrication and experimental.
