| 摘 要： | 利用Catia软件对某轿车车身的三维模型进行简化，导入到ANSYS Workbench中，对车身进行前置处理并检查有限元网格划分质量。模拟仿真车身弯曲和扭转工况，计算车身相应刚度值、应力分布和车身开口处对角线变化值。分析仿真结果表明该车车身的弯曲刚度和扭转刚度都有一定的不足，但车身开口对角线变形量在标准范围内，为整车的改进设计提供了参考。

| Abstract: | By simplifying the 3D model of a car body by using Catia software, importing it to ANSYS Workbench, the body finite element meshing quality is checked in pre processing. Through simulation of the working condition of body bending and torsion, the corresponding body stiffness is calculated as well as the stress distribution and the car body openings change of the diagonal. Analyses of the simulation results conclude that the car body bending stiffness and torsional rigidity have some shortcomings, but body openings diagonal deformation is within the scope of the standard,and this provides a reference for the design and optimization of vehicle structure. |
