Abstract: Good aerodynamic performance can improve the braking efficiency of the racing, which is the premise of high speed and safe driving of the racing. In this paper, the modeling of the front wing and the rear wing is optimized and analyzed, and the fluid simulation of formula student China (FSC) vehicle is carried out by means of accumulation method and control variable method. It is studied whether the optimization methods such as variable section and increasing chord length could effectively increase downforce and reduce drag. Firstly, the appropriate airfoil is selected in Profili airfoil library, and then the boundary conditions and initial conditions of the model calculation domain are set in Fluent to simulate the actual running conditions of the racing. According to the concept of aerodynamics, a set of aerodynamics kit is designed for the racing racing, and the structural parameters of the kit are further optimized, and then a set of optimal aerodynamic performance design scheme is proposed.
