Abstract
Automobile covers and its support parts are important components of the automobile frame, and the support plate affect the automobile life and its safety. Crack and wrinkle are two key factors affecting the forming of automobile support plate. In this paper, the upper support plate of the automobile front bumper beam was taken as the object to study, and the DYNAFORM software was used to simulate and analyze its stamping process and do orthogonal tests. In orthogonal test, the wrinkling and maximum thinning rate were selected as the evaluating index, and then the two weighted mean values were calculated, and the minimum value was selected as the optimal combination of the gap between punch and die (0.62mm), friction coefficient(0.125), stamping speed (4000mm/s). And the DYNAFORM run showed that high stamping quality was achieved with the optimization parameters.
