| 中文摘要: |
| 以SAE(美国机动车工程师学会)汽车模型为载体，分别装载普通轮胎、蜂窝式塑料轮胎和辐板式塑料轮胎，采用计算流体力学数值模拟的方法研究轮胎对整车气动性能的影响。通过比较3种模型的气动阻力、气动升力、速度场、压力场和湍流动能，分析造成差异的原因。结果显示，塑料轮胎对整车的气动阻力影响较小，但能够减小气动升力，尤其是辐板式塑料轮胎减小升力达13.27%。 |
| 英文摘要: |
| Based on SAE(Society of Automotive Engineers) car models with normal tire，spoke plastic tire and beehive plastic tire，the influence of the tires on the aerodynamic characteristic of car was studied by computational fluid dynamics numerical simulation method.By comparing the air drag，air lift，velocity field，pressure field and turbulent kinetic energy of three kinds of models，the reason for the difference was analyzed.The results showed that，the plastic tire had little effect on the air drag，but could reduce the air lift，especially for the spoke plastic tire with air lift reduction of 13.27%. |
