摘　　要：针对某车门外板存在的凹陷变形现象,运用联合数值仿真对车门外板进行抗凹性分析并进行优化。首先,利用Hypermesh进行CAE计算文件搭建;再应用均匀布点法,锁定车门外板关键区域加载点;进一步地,采用逐次加载法对车门外板进行加载与卸载;最后,调用ABAQUS求解计算,以获得载荷-位移曲线、车门位移云图和残余形变状态云图。结果表明,车门外板原状态关键区域的抗凹性不足,需对其优化改进。优化结果表明,P2点的最大位移减小了33.72%,残余变形减小86.66%;P3点的最大位移减小28.33%,残余变形减小96.58%。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 “ForceDisplacement” 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 %.
