摘　　要：为了提高赛车的成绩,FSAE赛车上通常会引入空气动力学套件来提高整车的操纵性。文章通过CFD对定风翼翼型、迎角、翼片布置等因素进行分析,确定了具备良好气动特性的定风翼设计方案;通过调整风压中心的位置影响车辆的实际轴荷分配,进而影响整车的转向特性;对赛车车身及涂装渲染的设计;通过CFD分析,整车升阻比达到2.9,整车具有较好的气动特性。In order to improve the performance of the car,the FSAE car usually introduces an aerodynamic package to improve the handling of the vehicle.In this paper,CFD is used to analyze the factors such as the fixed-air wing type,Angle of attack,and wing layout,so as to determine the Design scheme of the fixed-air wing with good aerodynamic characteristics.By adjusting the position of the wind pressure center to affect the actual axle load distribution of the vehicle,and then affect the steering characteristics of the vehicle,the design of the car body and painting rendering,through CFD analysis,the lift-to-drag radio of the vehicle reaches 2.9,and the vehicle has good aerodynamic characteristics.
