| Abstract: | The aerodynamic kit was designed for the FSC racing car from Wuhan University of Science and Technology. First, the fixed wing and the diffuser were designed and modeled, and the former was aerodynamically simulated and optimized by using FLUENT software. Secondly, the aerodynamic kit was fixed on the racing car, and the full car model was set up for aerodynamic simulation and analysis of the car under the common condition so as to determine the influence of the aerodynamic kit on the high-speed stability and turning performance of the car. The results show that the aerodynamic kit has greatly improved the high-speed stability and turning performance of the car. |
