摘要
FSAE赛车的轻量化设计很大程度上是靠有限元软件实现的,文章在CATIA中对FSAE传动系统建立三维模型,通过理论分析进行受力计算;针对传动系统中的架载荷特性,建立大链轮和偏心轮支架的有限元模型,对其进行模态与静力学分析,得到其安全系数云图,在此基础上,文章对链轮与支架的结构进行优化,使得镂空处的尺寸最合理,保证其在满足强度的要求下,质量最轻。通过对优化后的结构再次分析,结果表明该链轮与偏心轮支架的结构优化设计是可行的。
The lightweight design of FSAE car is largely realized by finite element software. In this paper, a threedimensionalmodel of FSAE transmission system is built in CATIA, and the force is calculated through theoretical analysis. For the loadcharacteristics of the frame in the transmission system, the finite element model of the large chain wheel and eccentric wheelsupport is established, and its modal and static analysis is carried out to obtain the safety factor cloud map. On this basis, thispaper optimizes the structure of sprocket and bracket, so as to make the dimension of the hollow-out most reasonable andensure the lightest quality under the requirement of strength. The results show that the optimal design of sprocket andeccentric support is feasible.
