For the problems of cracking and wrinkling in the drawing process of automobile panel for aluminum alloy, taking the aluminum alloy side frame of a brand automobile as an example, the manufacturability of part was analyzed, the addendum surface was designed, and the initial simulation and analysis were conducted. Then, the optimization schemes of cracking for door hole were mainly studied. The three schemes such as locking inner drawbead, optimization of R angle for blank line and reduction of stamping speed were proposed, and the influences of them on the cracking of door hole were researched. The simulation results show that the tangential cracking phenomenon at the door hole reduces by locking inner drawbead, but cracks appear in the panel, so this scheme is not feasible. However, the cracking of door hole has a great relationship with the R angle of blank line, and the passivation of R angle for blank line solves the problem of door hole cracking well. Furthermore, decreasing the stamping speed plays a role of auxiliary optimization in the stress concentration area of door hole, and the actual product is basically the same with the simulation results to have a good reference significance for the same kind of products.
