Aiming at the concave deformation of a certain vehicle front door panel,this paper conducts a concavity resistance analysis and optimization on the front door outer panel through a joint numerical simulation. Firstly, Hypermesh is utilized to construct the CAE calculation files. Secondly, the uniform distribution method is applied to fix the loading points in the key areas of the front door panels. Thirdly, the successive loading method is utilized to load and unload the front door panels. Finally, the ABAQUS solver is called for calculation to obtain the “Force-Displacement” curve,the front door displacement contour plot, and residual deformation contour plot. The results show that the anti-denting performance of the key area of the original state of the front door outer panel is insufficient, requiring optimization and improvement. The optimization results indicate that the maximum displacement at point P2 is reduced by 33.72 %, and the residual deformation is reduced by 86.66 %; the maximum displacement at point P3 is reduced by 28.33 %, and the residual deformation is reduced by 96.58 %.
