Wrinkling, cracking and springback are the main quality problems of stamping for automobile panel, which directly affect the surface, size and shape accuracy of parts. For the reinforced beam, the stamping process and springback were simulated by software Dynaform, and the influences of blank holder force, stamping speed, friction coefficient and clearance between punch and die on the thickness and the springback were studied by the orthogonal test and the range analysis as well as the evaluate indexes of the minimum thickness, the maximum springback, cracking and wrinkling, and the stamping process parameters and mold profile were optimized. By comparing the minimum thickness and the maximum springback of simulation analysis with the actual parts, the rationality of the optimization scheme and the accuracy of the simulation results were verified. The thickness of parts is effectively controlled between 0.85-1.15 mm,and the springback is controlled within 1.1 mm，which reduces the number of die repair and the production cycle.
