Initial numerical analysis of a small electric vehicle

This article presents a concept of a two-seat urban electric vehicle, whose model was developed in the FEM Nastran-in-Cad software. The performed simulations formed an optimization tool applied for the purpose of a study involving the distribution of the vehicle mass and its impact on the strength parameters of the body. The study focuses on the impact of the vertical road characteristics on the stress transferred through the vehicle’s body throughout drive conditions. In addition, a quasi-static analysis was performed with regard to the deformation of the load-bearing elements resulting from external impact forces with various magnitude and contact angle. In the article, the authors focused on the study of the impact of vertical road characteristics on the stress that is transferred through the vehicle body, as it occurs in driving conditions. The simulations presented in the article focus on the procedures applied during the analytical and numerical analysis with the purpose of developing an environment to test the structural components of the vehicle in terms of its response to vertical road roughness. The analysed system examined the impact of the road surface on the occurrence of stress and displacement in the structure of the body of the designed vehicle.
