Numerical simulation and analysis for aerodynamic devices of FSAE racing car

Abstract

Improving the aerodynamic characteristics of racing cars is one of the important means to improve the performance of FSAE.This paper completed the FSAE car body and aerodynamics device design and development, based on the CFD technology in the car's aerodynamic characteristics are studied.Through the analysis of the aerodynamic characteristics of the car body with and without aerodynamic devices, and the comparative analysis of airflow pressure and velocity distribution around the car body and aerodynamic devices, the simulation results show that the aerodynamic devices effectively improve the aerodynamic characteristics of the car, and better improve the control stability and driving safety of the car.
