车门屈曲抗凹性能提升方法研究

The Study of the Buckling and Denting Performance Improvement of the Doors

文章以ABAQUS分析软件为工作平台,采用结构非线性屈曲分析方法,对车门的屈曲抗凹性能进行了深入研究,以计算获得的最大位移、残余位移以及塑性应变为考察对象,重点研究了外板厚度、外板材料、增强垫及增强支架对车门屈曲抗凹性能的影响,并得出有效结论。

Used the finite element program ABAQUS and based on the nonlinear buckling analysis method, the buckling and denting performance of the doors is researched. According to the maximum displacement, residual displacement and plastic strain, the influence of the outer panel thickness, outer panel material, reinforcement pad and reinforcement bracket are researched respectively. Some valuable conclusions are drawn.
