Abstract

As the world focuses on tackling climate change and finding sustainable energy solutions, electric vehicles are becoming a vital part of building an environmentally sustainable future. One of the critical tasks faced by vehicle designers is the structural analysis of the chassis. This ensures the structural integrity of the vehicle as well as the safety and comfort of passengers. This study focuses on assessing the performance of an electric vehicle chassis under static loading conditions using two finite element methods: the conventional mesh-based method using Autodesk Inventor software and the meshless method using SimSolid software. Stress distribution, displacement, and safety factor were analyzed to assess the structural integrity of the chassis. The results showed a maximum stress of 98.11 MPa and a safety factor of 2.46 in Inventor, with SimSolid producing closely aligned results and a maximum relative error of 4.96% compared to the Inventor results. The findings confirm that the chassis experiences only elastic deformation, validating its structural safety for practical use. Additionally, the study highlights the efficiency of the meshless method in reducing computational time by eliminating the time- consuming process of mesh generation while maintaining accuracy, making it suitable for the structural analysis of complex chassis designs.
