摘　　要：论文以FSC赛车车架作为研究对象,主要研究FSC赛车车架静力学及模态分析以及基于灵敏度分析的轻量化设计。车架的有限元模型使用HyperMesh进行处理,通过对车架有限元赋予4种工况特性,分析车架的强度和刚度。车架的轻量化设计以管件壁厚为设计变量,以1阶模态频率和质量的相对灵敏度系数为变量筛选条件,以加载点位移、车架1阶模态频率为约束条件,以质量最小为目标函数,进行轻量化优化,最终实现车架减重4.6Kg。This paper takes FSC racing frame as the research object,and mainly studies the static and modal analysis of FSC racing frame and lightweight design based on sensitivity analysis.The finite element model of the frame is processed using HyperMesh,and the strength and stiffness of the frame are analyzed by assigning four working conditions to the finite element of the frame.The lightweight design of the frame takes the pipe thickness as the design variable,the first-order modal frequency and the relative sensitivity coefficient of the mass as the variable selection conditions,the displacement of the loading point and the first-order modal frequency of the frame as the constraint conditions,and the minimum mass as the objective function to carry out the lightweight optimization,and finally realize the frame weight reduction of 4.6kg.
