| 摘 要： | 车架质量占赛车整车质量的比例很大，其在轻量化方面存在可优化空间。利用CATIA设计一种钢管桁架结构和单体壳结构的复合式车架，在HyperMesh中建立有限元模型，对车架的单体壳部分进行尺寸优化，确定不同区域层合板的最佳厚度，最终得到的车架质量为21.8 kg，扭转刚度为4 057 N·m/(°)，较纯钢管车架减重约5 kg，刚度提高约1倍，满足设计目标。

| Abstract: | Frame mass accounts for a large proportion of whole racing car mass, therefore it can be optimized for lightweight design. A frame which composites steel tube truss structure and monocoque structure is designed using CATIA, a finite element model is built in HyperMesh, the size of the frame monocoque parts is optimized, and the optimum laminate thickness in every area is determined. The mass of final optimized design frame is 21.8 kg, which is about 5 kg less than that of the pure steel frame; its torsional stiffness is 4 057 N·m/(°), which is about twice of the pure steel frame mass. The optimization result meets the design object. |
