摘      要：To improve the accuracy of the vehicle crashworthiness simulation,it is necessary as well as important to integrate the valid forming effects of key *** has been agreed by many that one-step simulation results should be used only as a qualitative trend of the part but not as an engineering result for further structural analysis,especially for a relatively complex *** study shows that it is inaccurate to analyze the forming effects with one-step simulation based on the geometry of the final part through comparison with the incremental simulation and verification with the actual part,whether in thickness or in plastic ***,incremental simulation is very time consuming and infeasible in the early stage of vehicle design due to lacking of forming tools and process *** engineering approach is proposed to meet the requirement of accuracy as well as the time efficiency,where one-step simulation is conducted based on the geometry of the transformed part instead of the final *** geometry of the transformed part is generated by simple die design engineering and proves to offer much more accuracy than the one-step simulation based on the final part geometry.
