Design and Analysis of Chassis for Green and Light Vehicle Using Composite Material.

Abstract

Nowadays, transportation industry plays major role in the economy of modern developing and industrialized countries. Weight reduction is now the main issue in automobile industries. The chassis frame is an important part in automobiles. The main function of the auto mobile chassis is to carry the goods and pay load placed uponit. So it must be strong enough to resist the shock, wist, vibration and other stresses. In the present work, the dimensions of an existing light vehicle chassis of a TOYOTA (LJ150-GKMEE) vehicle is taken for modeling and analysis of a vehicle chassis with composite materials namely S-GLASS epoxy and HSLA Steel, subjected to the same load as that of a steel chassis. Reduction of weight of various parts of a vehicle can improve the performance and efficiency of the automobile. The composite materials provide a good strength-to-weight ratio, which could be re placed for the conventional materials. This paper deals with the structural analysis of a frontend crossbar which is replaced with s-glass Fiber Reinforced Polymer composite material. Maximum stress and maximum deflection are important criteria for design of the chassis. The objective of present is to determine the maximum stress, maximum deflection. For validation the design is done by applying the vertical loads acting horizontally in the existing cross sections. To do this research I use The FE analysis for a light modeling by utilizing commercial finite element analysis software packages like CATIA and ANSYS. Then I contribute light and high strength chassis for light and green vehicle.
