Abstract: To enhance the cornering performance of formula student China, this paper designs an aerodynamic package including a front wing, side diffusers, and a rear wing. Computational fluid dynamics simulations of the racecar are conducted using ANSYS software, and the front wing is optimized based on the simulation results. Additionally, the downforce and lift-to-drag ratio of the racecar under five different installation configurations are compared. The results show that after installing the complete aerodynamic package, the downforce is increased by 355.6 N, and the lift-to-drag ratio is improved from -0.437 6 to 3.021 2, effectively enhancing the performance of the formula racecar.
