Abstract：

The process parameters of automobile engine cover forming were studied, and the forming process was simulated by Dynaform. Then, the blank holder force, friction coefficient, punching speed and the gap between punch and die were optimized, and the optimum forming scheme was given with the maximum thinning rate 27.52% and the maximum thickness rate 9.48%. Furthermore, the actual drawing test was conducted based on simulation and orthogonal optimization, and the forming property was consistent with the finite element modeling results. The research results show that the optimization of stamping process parameters is feasible based on the orthogonal experiment method, and it can shorten the testing period and improve the forming quality of product.
