Simulation analysis of external flow field of FSE electric car is carried out by using CFD technology for comparison of air flow on the surface of car body before and after installation of aerodynamics devices. After determining the magnitude of the pressure generated by the aerodynamics devices and the impact on the airflow of the whole vehicle, the combination of the tail angle of attack suitable for different competitions is determined according to the rules of FSC. Finally, the angles of the rear wing are changed according to a certain change gradient to explore the change law of the aerodynamic parameters of a racing car with the angle change. It provides a reference for the development of the DRS system.
