为确保FSC赛车的安全性能,本文以车架结构为研究对象,建立车架有限元模型,利用 Workbench软件对车架的弯曲和扭转工况进行分析,同时,分析了车架结构的固有频率和振型,并将分析得出的结果与材料属性进行比较。结果表明,在弯曲工况下,车架最大变形为2.15 mm,车架刚度满足要求；在扭转工况下,左前轮和左后轮悬空扭转车架最大变形量在发动机的固定吊耳处为2.50 mm,车架的其他部分基本变形量在1.30 mm和1.70 mm左右,小于车架材料的屈服极限,车架符合设计要求。该研究为车架动态响应性能和结构的改进设计提供了理论依据。

In order to ensure FSC racing safety performance,this paper takes the frame structure as the re-search obj ect,establishing the finite element model of frame,uses the Workbench software for the exami-nation of bending and torsion condition analysis of frame,compares the results of the analysis and material properties.At the same time,it proceeds with free modal analysis calculations on the frame,and analyzes the natural frequency of the frame.The results showed that,in the bent condition,frame maximum de-formation was 2.15 mm,which meet the requirements;in reversing the conditions,with the left front wheel and the left rear wheel dangling,the maximum deformation amount of the torsion frame fixed in the engine at the lifting lugs of 2.50 mm,the basic amount of deformation of the other portion of the frame a-bout 1.30 and 1.70 mm,and less than the yield limit of the frame material.Frame was in accordance with the design requirements,and the study provided a theoretical basis for the frame dynamic response per-formance and improved the design of the structure.
