Abstract: Aerodynamics system design and analysis is an important part of formula racing. The design and analysis of this paper is based on the aerodynamics package of the formula car designed by the formula team of Beijing Institute of Technology Zhuhai Campus. Firstly, a complete racing model is established by 3D modeling software CATIA, and then the model is imported into CFD software for numerical simulation. Finally, through CFD software analysis, it is concluded that the negative lift of the racing car equipped with aerodynamic system increased from -34 N to 411 N in the wind speed of 20m/s, and the resistance of the front wheel after installing the front wing is reduced by about 33%.
