Shape Optimization of Heavy Vehicle Chassis

A chassis consists of an internal vehicle frame that supports a manmade object in its construction and use. An example of a chassis is the under part of a vehicle, consisting of the frame (on which the body is mounted). If the running gear such as wheels and transmission, and sometimes even the driver’s seat, are included, then the assembly is described as a rolling chassis. The main objective of this project was to modify the design to decrease the deformation of chassis. The design was done using CATIA, which is advanced modelling software. In these two types of analysis were done one is model analysis and the other is deformation and stress analysis. In the model analysis deformations were finding with natural frequencies and in static analysis deformations were to find the shape deformation and high stress of component was finding before and after modification of chassis
