基于有限元分析的赛车车架结构轻量化设计

Lightweight design of racing car frame based on finite element analysis

通过对某方程式赛车车架结构的有限元分析,来实现赛车车架结构的改进和轻量化设计。利用CATIA软件平台建立某方程式赛车车架三维实体模型,运用CAE分析软件对其进行单元选取和网格划分,建立车架的有限元分析模型,通过对车架静态条件下弯曲工况、扭转工况的分析,找到车架弯曲强度和扭转刚度富裕部位,通过减少管件的使用数量、减薄相对应管材的壁厚、减小直径,达到车架结构优化和轻量化设计目标。

The three-dimensional practical model of undercarriage of the racing car was established by using CATIA,and finite element analysis was carried out by using CAE.The typical going of the undercarriage in the static state was analysed.Via the analysis,the intensity and the rigidity of the different parts of the undercarriage was found,then relevant improving measures were put forward,so the basis of design light-undercarriage was established.
