| 摘 要： | 为研究汽车行驶时,气动升力随着车速的提高,对汽车的操纵稳定性和动力性的影响,研究气动升力的附加装置.以一跑车模型的尾翼为基础,采用一种修正湍流模型的数值计算方法,探讨了外形、攻角、翼面凹坑以及支架形式对尾翼表现的影响.结果表明:后负升力翼产生的负升力与外形和支架形式有很大关系,且随着攻角的增大而增加,而翼面凹坑能起到增加负升力的作用.

| Abstract: | With the velocity getting larger when automobiles are running, the aerodynamic lift influences the steering stability and the dynamic property greatly. To study the aerodynamic lift caused by wing and its accessory, the rear wing of a sports car was taken as the research object. By using the method of compute fluid dynamics (CFD) simulation, the influence of rear wing factors on the aerodynamic lift was investigated, such as: the shape, attack angle, concave pits on the wing surface and the bracket form. The result shows that the negative aerodynamic lift caused by the rear wing has a lot to do with the shape and bracket form. With the increase of attack angle, the negative aerodynamic lift is getting larger. In addition, the concave pits on the wing surface contribute also to the negative aerodynamic lift. |
