方程式赛车车架轻量化分析研究

Lightweight Formula Frame Analysis Research

摘要: 方程式赛车车架是整车各总成及零部件的装配和承载基体。它所占赛车整备质量百分比10%以上，因此轻量化的车架可以提高赛车的燃油经济性、动力性及操纵稳定性等动态性能。本文首先分析了车架设计标准与规则，研究了钢管车架设计优化方法。然后建立FSC赛车车架的三维几何模型，将几何模型导入到有限元软件中，建立了车架的有限元模型，对车架进行了静态受力分析和模态分析，根据仿真分析结果进行结构优化和轻量化设计，最后确定赛车车架方案，实现车架减轻质量1.4 kg结构优化目标。本文轻量化设计方法对赛车或其他工业制品设计制造有重要借鉴意义。

Abstract: Formula racing frame is the vehicle assembly and components of the assembly and bearing the base. It is more than 10% of the quality of car racing, so the lightweight frame can improve the car's fuel economy, power and handling stability and other dynamic performance. In this paper, the design criteria and rules of the frame are analyzed, and the optimization method of steel frame design is studied. Then, the 3D geometric model of the FSC racing frame is established, the geometric model is introduced into the finite element software, the finite element model of the frame is established, the static force analysis and the modal analysis are carried out on the frame, and the structure optimization and lightweight design are analyzed according to the simulation results, and finally the racing frame program is determined to achieve the framework to reduce the quality of 1.4 kg structure optimization goals. The lightweight design method has important reference for other industrial products design and manufacture.
