Comparing Study on Real Drawbead and Equivalent Drawbead based on finite element analysis

摘要：

　　The dynamic explicit finite element software DYNAFORM was used to simulate the real and equivalent drawbead model.Analyzed the influence of the blank hold force (BHF) and virtual velocity on blanks deformation behavior after passing through drawbead,compared the results of the FE simulation.The simulation results were confirmed by experiments.The study shows that the equivalent drawbead model cant simulate the blanks behavior precisely when it passing the real drawbeads,the effect of BHF on real drawbead model is larger than equal drawbead model; the proper range of virtual velocity was obtained at the same time.
