Abstract：

Automotive panels mainly consist by stampings, and the design of stamping die is closely related to the forming quality of automotive panels. The drawing process of an automotive anti-collision beam supporting plate was simulated by the DYNAFORM, and some parameters such as the stamping speed, drawing rib layout，blank holder force and clearance between punch and die were selected and designed. By analyzing the thickness distribution of the above part, the forming result was evaluated according to thickness difference, and the parameters combination with good forming effect were determined. The simulation results show that after the equivalent solid drawing drawbead of the die is designed, the best forming result is obtained with blank holder force 360 kN， stamping speed 4000 mm·s-1 and clearance between punch and die 0.66 mm. The die design and results of simulations can provide a design reference for other anti-collision beam supporting plate of types automotive.
