The chassis of an automobile is a crucial component. The body and other components of the vehicle are supported by the chassis, which acts as a framework. It must also be sufficiently stiff to endure twist, vibration, shock, and other forces. The main objective of this study is to analyze and find suitable lightweight materials for an automobile chassis. The material must withstand the entire load carried by the chassis. Currently materials with steel alloys are used in the chassis, but they are heavy. With increasing the weight of the chassis, the load on the engine increases and the performance of the vehicle slows down. Thus, lightweight materials to increase vehicle performance like aluminum alloy can be used. In this work steel alloy ASTM A710 (currently used material), two aluminum alloys AA 6063 and AA 7075 are considered. These material properties are applied to the ladder type chassis and analyzed under maximum load conditions. This ladder chassis is designed with a C cross-section to minimize weight. Because they take longer and cost more money, traditional design procedures that include manual calculations and experimentation are becoming less preferred now. The design process is now far more efficient thanks to advancements in numerical techniques, computer power, and computer-aided engineering (CAE) in general. The chassis are modelled in SOLIDWORKS with appropriate parameters in this research. Analysis for various configurations based on the model and theoretical calculations of the material is done in ANSYS. It was found that Aluminum AA 7075 outperformed other two materials in terms of withstanding loads on the chassis while being lightweight. The detailed comparison of stress, shear stress, and deformation for the various materials highlighted the advantages of Aluminum AA 7075 in enhancing the structural integrity and load-bearing capacity of the truck chassis.
