Abstract：

The developing period and quality of the automobile cover is difficult to be guaranteed because of its large size, stamping difficulty,cracks at the corners and the winkles at the edge. It used to be designed and manufactured by trial-and-error method and the experiences,which is not only difficult to guarantee its development cycle and quality but also increase its development cost.Based on analysis on its drawing process,the numerical simulation of drawing process for car's cover was studied by Dynaform software and its blank holder force and drawbead were optimizazed in order to get rational technological parameters.Accordingly the development cycle would be shortened and development cost would be reduced.
