The Chassis is the most integral part of the vehicle. It is the frame of the chassis on which the entire body of the vehicle is built. The entire external load of the vehicle including its self-weight is on the chassis. Thus, this chassis design and its analysis forms the most important part of the vehicle manufacturing. This paper deals with the structural analysis of a light duty automobile chassis which is replaced an existing material (Grey Cast Iron) by ASTM A710, AISI 4130 steel and Al6063. Material properties are applied on an automobile chassis and analysed under maximum load conditions. An automobile chassis is modelled in Solid Works with the appropriate dimensions. Analysis for the different materials is done in ANSYS based on the model.
