Structural analysis of new modular and lightweight automobile body structure

Abstract

Improvement of safety, reduction of energy consumption, and reduction of emission become one of the most highlighted issues for automotive industry in recent years. One of the most significant solutions, i.e. lightweight car body has been described in this project. Design, implementation, and characterization of parameters of lightweight car body are used as well. Moreover, modular structures enhanced the rate of purchase and production. Based on design specification, the new modular and lightweight chassis concept has been established. In the beginning of the simulation a beam model has used. Three primary simulations, bending stiffness, torsional stiffness, and modal analysis have implemented. Therefore, the confirmed results used as a baseline for making a more complex model. This model used shell element, which it can be used for performing second simulation that is more accurate and compatible with crashworthiness simulation. To get the reason appropriate results, proposed design process has been approved. This design flow is the last outcome of this project. Following this procedure leads us to design a lightweight and modular chassis based on SAE standard.
