摘　　要：车身外板是汽车车身上重要的外覆盖件,但结构特征少、局部刚度弱.客户在选购车辆时,可能会对车身外覆盖件表面进行按压,如果刚度不足,容易导致大面积变形,影响客户对车辆的印象.为在设计初期保证车身外板的抗凹性能,降低后期问题的出现,以某车型车身外板为例,阐述应用Abaqus进行表面抗凹陷特性分析和优化过程,结果能够满足客户的使用要求.The side panel of vehicle body is an important part, but it has less character to have enough stiffness. When the customers buy a new car, they often press on the car body panel. The weak side panel stiffness can easily lead to the deformation of body panel, which dissatisfies the client. In order to ensure the side panel stiffness and reduce the emergence problem, the characteristics analysis and optimization on the dent resistance of car side panel resistance analysis case，the results can meet the customer’s requirement.
