| 摘 要： | 汽车在高速公路上会车时,空气流场对汽车行驶稳定性有很大影响。本文利用通用流体分析软件,建立两汽车会车的有限元模型,对其外流场进行流体动力学仿真,得到两汽车会车时的侧向压力和速度,分析其外流场对汽车行驶稳定性的影响。根据仿真的结果,提出了提高汽车会车时行驶稳定性的措施,以保证汽车行驶的安全性。

| Abstract: | The external flow field will affect the driving stability of the car when it is traveling on the expressway.The paper,employing the general fluid analysis software,builds the finite element model of meeting cars,carries out the external field fluid dynamics simulation,attains the lateral pressure and the speed of the two meeting cars and analyses the effect of the external flow field on the driving stability of the automobile.Based on the simulation results,the paper puts forward the measures to improve the stability and ensure the safety of the automobile. |
