Paper Title:
Study on Accuracy Improvement of Vehicle Crash Simulation Considering Stamping Effects
  Abstract

It is general preferable to consider stamping effects of sheet metal forming for vehicle crash simulation nowadays. However, the present approaches for stamping simulation and coupling forming results to crash finite element model require massive pre-works. To overcome these difficulties, an inverse method for rapid and simple stamping simulation using HYCRASH is introduced, where crashworthiness analysis of front side rail under frontal crash was used as an example in this study. A detailed stamping simulation by AUTOFORM is used for comparison, also accompanied with the one without stamping effects. Through comparison of stamping results and frontal crashworthiness performance, it is concluded that effective plastic strain makes more contribution on simulation accuracy than thickness reduction, and HYCRASH shows an attractive approach for stamping analysis than AUTOFORM coupled in crash simulation in the context of computational cost.
