Chassis is a major component in a vehicle. In chassis different type of failures are occurring due to static and dynamic loading condition. In this present work, static and dynamic load characteristics are analysed using FE models from this work. It is found that identifying the location of the high-stress area, analysing vibration, natural frequency and mode shape by using the finite element method. Modal updating of car chassis model will be done by adjusting the selective properties such as mass density and Poisson’s ratio. Predicted natural frequency and mode shape will be found by using Solid works software. The cad geometry of chassis is generated in solid works and model analysis is done in Solid Works.
The chassis frame forms the backbone of a heavy vehicle; its principal function is to safely carry the maximum load for all designed operating conditions.
This paper describes the design and analysis of heavy vehicle chassis. Weight reduction is now the main issue in automobile industries. In the present work, the dimensions of an existing heavy vehicle chassis of a TATA 2515EX vehicle is taken for modelling and analysis of a heavy vehicle chassis with three different composite materials namely, Carbon/Epoxy, E-glass/Epoxy and S-glass /Epoxy subjected to the same pressure as that of a steel chassis. The design constraints were stresses and deflections. The three different composite heavy vehicle chassis has been modelled by considering three different cross-sections. Namely C, I and Box type cross sections. For validation, the design is done by applying the vertical loads acting on the horizontal different cross-sections. The software is used in this work Solid Works for both modelling, analysis.
