基于FSAE赛车的空气动力学套件设计及CFD分析

Design of an Aerodynamic Package for FSAE Racing Car and CFD Analysis

在赛车领域,空气动力学研究已经成为各项赛事以及车队之间竞争的焦点。文中通过对G03C赛车进行整车空气动力学分析,找出整车造型对空气动力学的影响因素,并根据空气动力学原理设计了一套相匹配的空气动力学套件,包括鼻翼、尾翼及扩散器。对比改装前后赛车的空气力学性能,结果表明,安装空气动力学套件后,产生一定的下压力使得赛车的高速稳定性能得到提升。

In the field of racing cars,air dynamics research has become the focus of competition between the events and teams.For Formula SAE,aerodynamic research is very important.This paper through aerodynamic simulation analysis of G03 C racing car,finds out influence aerodynamic factors of the vehicle model,and designs an aerodynamics package for it according to the principle of aerodynamics,including the front wing,rear wing and diffuser.Compared the aerodynamic performance of the car before and after modification,the results show that the increase of pressure makes the car high-speed stability improve under suite aerodynamic package.
