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 automobile chassis is
to carry the goods and payload placed upon it. So it must be strong enough to resist the shock,
twist, 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 modelling 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 replaced for the conventional materials. This paper
deals with the structural analysis of a frontend cross bar 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.
