To maximize energy absorption of EV body structure in frontal collision,vehicle front-end structure is designed by analyzing the characteristics of the optimal collision waveform configuration,and combining theoretical and empirical formulas.Meanwhile,deformation modes such as bending are introduced,and a method to improve vehicle structure frontal collision property based on the theoretical optimal waveform configuration is proposed.The results show that the collision waveform of the improved vehicle body structure is basically consistent with the optimal waveform configuration,and there is a significant decrease in passenger acceleration,which improves the overall safety of the vehicle.
