| 摘 要： | 在侧风为0、1、2-10m／s的情况下，利用计算流体力学软件ansys cfx对某型号简化汽车模型进行数值模拟，并对结果进行处理与分析。分析结果表明，随着侧风的增大，侧向力和升力增大显著。而阻力受侧风影响不大。侧风的增大使得升力、侧向力明显增大，进而严重影响了汽车的行驶稳定性。

| Abstract: | Under the effect of crosswind velocity of 0,1,2,~10m/s,the outflow field of a simplified car is simulated numerically by applying general purpose computational fluid dynamics(CFD) code ansys cfx.Then analyzing and discussing of results is maked.It shows that the crosswind only has slight influence on the drag force.While the side and lift force increas remarkably with the increase of crosswind velocity.As a result of it,the driving stability of the car is affected. |
