Finite Element Simulation of Welded Rectangular Profiles for Electric Vehicles

Recently, the fatigue phenomenon of welded structure is more complicated in different industries, especially in the case of electric vehicles (EVs). In fact, there are various parameters that can affect this phenomenon as: the detail of geometry, the nature of material, the quality of the welding process and the environment. In this paper, a three dimensional of finite element simulation was built to estimate the fatigue life of a structure based on welded rectangular profiles for transportation utilization. The results indicated the life cycle analysis of our structure, the location of the critical areas at the vicinity of the welded joint and, the loading history impact on life design which is represented in form of a curve showing that the loading variations are reduced with an increase of durability.
