Abstract: With the increasing popularity of electric vehicles, the market pays more and more attention to the safety of electric vehicles, especially the battery safety in the process of collision. This paper analyzes the simulation analysis method of electric vehicle rear-end collision based on Ls_Dyna finite element simulation analysis software, describes the basic requirements of rear-end collision simulation analysis, model establishment, analysis method, and simulation results postprocessing requirements. Through the use of standardized virtual development technology, greatly shorten the development cycle and development cost. The simulation analysis method has a good guiding role for the pre-test investigation, optimization verification and performance improvement.
