Abstract: Denting resistance performance of the door outer panel is one of the important evaluation indexes of the body, the lack of its performance will reduce the quality of the products, and effect the subjective feelings of customers. In order to solve this problem, In this paper, the denting resistance performance of the door outer panel was simulated based HyperMesh, the unqualified pressure point was optimized by changing the structure stiffening plate and adding reinforcing sheet, and through the test to verify this optimized scheme. The experimental results show that the simulation is effective, and it provides a reliable basis for optimizing the structure of the door out panel.
