Abstract：

The numerical simulation of drawing process for car's taillight pedestal is studied by using the three-dimensional sheet metal forming analysis and non-linear explicit algorithm software Dynaform.And the influence of different shape of addendum and different shape of blank is analyzed in the stamping simulation.Compared with the FLD diagram and the results of deforming,the optimized shape of addendum and the economical blank size is obtained.It is helpful to know that how to design die face in manufacturing the related parts.
