【Abstract】 Sheet metal forming is widely applied to automobile, aviation, space flight, ship, instrument, and appliance industries. Based on Parametric FiniteElement Analysis (PFEA), this paper researches thoroughly on the problems of process parameters optimization of sheet metal forming. The interactive PFEA approach is used in order to obtain the optimum blank shape for square box deepdrawing. And the result accords with the result of publication. The research shows that PFEA method of author’s scheme for process parameters optimization of sheet metal forming has high accuracy and efficiency. 更多还原
