摘要： 为提高中国大学生方程式赛车的过弯能力，文章设计了包括前翼、侧面扩张器和尾翼 的空气动力学套件。通过 ANSYS 软件对赛车进行了流体力学仿真，并根据仿真结果优化了 前翼。同时，对比了五种不同安装情况下赛车的下压力和升阻比。结果显示安装所有空气动 力学套件后下压力提升了 355.6 N，升阻比也从-0.437 6 提高到了 3.021 2，有效地提高了方程 式赛车的性能。

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.
