摘要
为配合建立中国大学生方程式汽车大赛(FSAE)赛车的虚拟样机模型,根据FSAE赛事规则要求,对赛车悬架系统进行了结构设计。根据设计思路对轮辋、轮距及前后悬架立柱等相关部件进行了选择与设计,在确定采用不等长双横臂式悬架类型的基础上对弹性元件、减振器和导向机构的主要结构尺寸进行了设计计算,并应用软件Pro/E进行了三维建模设计,同时在SolidWorks环境下对前后摇块进行了强度校核。结果表明,前后摇块的最大合位移分别为4.260×10-3,2.838×10-2mm,最大变形均很小,设计的FSAE赛车悬架系统能够满足参赛要求,为进一步的实车研制提供了参考依据。
Abstract：In order to establish virtual prototype car model for FSAE and based on competition rules of FSAE. the paper introduces the suspension system structure design of racing car. Selection and design of rim, wheel track as well as front and rear suspension strut have been conducted. When unequal-length wishbone suspension is selected, the paper calculates the major dimensions of flexible components, absorber and guide mechanism, establishes 3D model with the help of the software of Pro/E as well as conducts strength check for major supporting parts by software of SolidWorks. The results show that the maximum displacement of the supporting parts is4.260×10-3,2.838×10-2mm respectively, a pretty small deformation. Therefore,tile suspension design can meet tile requirements of FSAE racing car, which also provide reference for car research and production.
