Weight Optimization of Chassis of an Automotive Vehicle using ANSYS

Abstract

The objective of this paper is to find out the most favourable material and immensely fitted cross-section for TATA 11O9 TRUCK ladder chassis. This research aims to optimize the weight of the chassis. For this we have taken three materials like structural steel, carbon fiber and Aluminium silicon carbide metal matrix composite. The automotive chassis is the vehicle's base, providing strength and support to the numerous body sections such as suspension, engine, power train, and so on. Recent advancements in the realm of automobiles have expanded rapidly, particularly in the current context. Problem faced by modern days vehicle is the heavy weight. So here we try to decrease the weight of chassis frame by using various method and increase the strength, efficiency of chassis. Reducing the weight of chassis results in increase in performance of vehicle, reduce fuel consumption, less wear and tear of tire. The designing of the chassis is done on software SOLIDWORKS and further analysis is done on ANSYS19.2. The current chassis mass with traditional material is 1560 Kg which is made up of structural steel, whereas the chassis mass with Aluminium carbide metal matrix composite material is 523.45 Kg. According to the analysis, the chassis mass has been reduced by 66.44%, which would eventually hinder the vehicle's performance.
