摘　　要：为提高FSAE赛车在比赛时的速度并达到减少污染尾气排放和节约能源的目的,设计者一直试图使用新材料完成赛车车架结构的轻量化设计。为此,使用碳纤维树脂基复合材料HTA/6376C,依据复合材料层合板设计原则进行铺层设计,开展FSAE赛车车架的轻量化设计。首先建立了车架的有限元模型;然后根据赛车实际运用时的典型工况施加载荷,利用有限元分析软件求解并确定了危险点;最后基于最大应力准则对危险点进行了强度校核。研究结果表明:在满足强度要求的基础上,车架结构减重近11%,达到了较好的轻量化效果;研究结果为FSAE赛车车架轻量化设计的新材料选取提供了基础数据。In order to increase the speed of FSAE racing cars during racing and achieve the goal of reducing pollution emissions and saving energy,designers have been trying to use new materials to complete the lightweight design of the racing car frame structure.To this end,carbon fiber resin matrix composite material HTA/6376C was used to carry out ply design based on composite laminate design principles to carry out lightweight design of frame materials for FSAE racing cars.First,a finite element model of the frame is established,loads are applied based on typical working conditions during actual use of the racing car,finite element analysis software is used to solve and determine dangerous points,and the maximum stress criterion is selected to conduct strength verification on the dangerous points.The research results show that on the basis of meeting the strength requirements,the structural weight is reduced by nearly 11%,achieving a good lightweight effect;the research work provides basic data for the selection of new materials for the lightweight design of FSAE racing car frames.
