Abstract：

Based on the DynaForm 5.9 simulation software, for the engine cover inner plate of an off-road vehicle, the finite element model was established, and the billet optimization, parameter setting of material and mold, design of process addendum and process parameter setting of stamping speed and drawbead size, etc. were conducted. Then, the influences of punching speed, blank holder force, clearance between punch and die and friction coefficient on the forming quality of inner plate parts were analyzed by the orthogonal test simulation and variance analysis, and the optimal forming process was selected. Furthermore, the optimization process was verified by experiment. The results show that the experiment and simulation results are consistent with each other, and the main body of part forms better. Therefore, the reliability of simulation results is verified by the rate of wastes within 0.05%, and the deviation between simulation and actual thicknesses of inner plate is within 2.5%.
