For the problems of long development period and high manufacturing cost for passenger car with body-in-white, taking the fender of a Dongfeng Honda SUV model as an example, combining product structural characteristics, a parameterized trial stamping process which can be modified rapidly was designed by the use of CAD/CAE collaboration, and the feasibility of trial stamping process was verified by finite element iterative solution technology AutoForm. Before the trial stamping die structure was designed, some potential forming defects were recognized and solved. According to the numerical simulation result and 3D die surface, and based on the concepts of short process and light weight, the size of trial die was minimized, the structure of trial die was simplified, the weight coefficient of trial die was reduced, and the standard component such as guide plate, location pin and pressure source parts were cancelled. Finally, the trial die structure with the low cost was designed, and the prototype parts that meet the requirements of vehicle matching were produced quickly through debugging. The results show that the parameterized trial stamping process based on CAD/CAE collaboration shortens the period of prototype part development and reduces its cost.
