基于有限元的FSC赛车踏板支座拓扑优化分析

Topology Optimization Analysis of pedal support of FSC Racing car based on finite element method

为了在中国大学生方程式汽车大赛(FSC)动态竞赛中获得良好的参赛成绩,挑战用最短时间在规定赛道上行驶,同时对赛车燃油经济性提出更高的要求。赛车整车设计流程中,在满足结构强度、刚度的前提条件下,尽可能降低整车质量,对提升赛车的动力性以及燃油经济性有着积极的意义。本文通过对FSC赛车操作踏板支座进行包含三维模型建立、拓扑优化、模态分析的拓扑优化设计分析流程,实现了FSC赛车设计过程中的轻量化设计,同时在保证强度条件下进行了模态分析,证明该部件满足实际使用要求,对实现赛车轻量化设计有积极作用。

In order to obtain good results in the FSC dynamic competition, the challenge is to drive on the specified track in the shortest time, and at the same time put forward higher requirements for the fuel economy of the car. In the process of racing car design, under the requirements of structural strength and rigidity, the weight of the whole car structure is reduced as much as possible, which can greatly improve the power and fuel economy of the car. In this paper, through the topology optimization design analysis process of the FSC racing pedal support including three-dimensional model establishment, topology optimization, and modal analysis, the lightweight design in the FSC racing design process is realized, and the modal is carried out under the condition of guaranteed strength. The analysis proves that the component meets the actual use requirements and has a positive effect on realizing the lightweight design of the car.
