摘要：

In order to study the aerodynamic characteristics of the racing car under the crosswind effects, a yawing model method was proposed for the simulation and experiment of the 2015 Jilin University's Gspeed racing car. Analyzing the flow field velocity and pressure distribution under different crosswind, the differences of aerodynamic force and the tail flow field were studied to get corresponding aerodynamic coefficients. The results show that the drag coefficient and side force coefficient of the racing car increase with the yaw angle, however, the lift coefficient changes without the linear change of yaw angle. And the down force of the racing car is mainly provided by the front and the rear wings. With the increasing of the yaw angle, the down force of the rear wings decreases and the down force of the bottom floor increases. The drag provided by the car body is more sensitive with the yaw angle. There is a difference of the vortex behind the racing car at different yaw angles. © 2019, Editorial Department of Transaction of Beijing Institute of Technology. All right reserved.
