Abstract：

Drawbead application is an effect method in sheet metal deep\|drawing process to control material flow In sheet metal numerical simulation,equivalent drawbead model is usually used to save CPU\|time In this paper,an equivalent drawbead model is established according to some domestic and foreign literatures Effects of drawbead restraining force,plastic thickness strain,and drawbead lift force are considered in the model and all of these are implemented in our FEM code A simulation example is given in paper
