Modelling Evaluation of a Heavy Vehicle Chassis by Using Materials E- Glass Epoxy & S-2 Glass

Abstract

Vehicles chassis consists of an assembly of all the essential parts of a truck (without the body) to be ready for operation on the road. Composite material is a material composed of two or more distinct phases (matrix phase and dispersed phase) and having bulk properties significantly different from those of any of the constituents. Different types of composite material are available and one of it is Polymer matrix composite. It is very popular due to their low cost and simple fabrication methods. It has the benefits of high tensile strength, high stiffness and good corrosion resistance etc. At present this polymer matrix composite materials are used in aerospace, automobile industries due to it high strength to low weight ratio. In this paper we design and model the heavy vehicle chassis by using Pro/Engineer software, by taking the data from the L & T heavy vehicle model by reverse engineering processes. Present used material for chassis is steel. The main aim is to replace the chassis material with E- GLASS EPOXY & S-2 GLASS. By using steel, the weight of the chassis is more compared with E- GLASS EPOXY & S-2 GLASS, since its density is more. Structural and Modal analysis is done on chassis for optimizing above parameters under 10tons load. Software used for modeling Pro/Engineer and for analysis ANSYS
