Abstract：

For the problems of crack and wrinkle of the strengthening plate in automobile body during drawing process, the multiobjective optimization experiments were designed by orthogonal test, and the multiobjective optimization model was established by setting the crack evaluation function Φ1 and wrinkle evaluation function Φ2 as the objective function and blank holding force F, friction coefficient μ, drawbeads resistance coefficient P1 and P2 as factors. In the end, the optimal solution was confirmed with F=1400 kN, μ=0.12, P1=0.05, P2=0.3 by comparing expected values. Finally, the quality of the parts obtained in the actual test verification was good, which met the requirements in actual use.
