翻译：图9为原始模型和两种方案转向架2表面的摩擦风速对比吹气速度为4 ms吹气改变了转向架区域的流场特性因此转向架表面的摩擦速度也发生了变化。表3给出了在吹气作用下转向架2部件表面摩擦风速增大的平均值可见方案1的摩擦风速较方案2的摩擦风速大各减振器上的摩擦风速均较原始模型的高也就意味着这些部件上的雪粒会承受更大的剪切力导致雪粒发生不稳定沉积。

Figure 9 shows the comparison of the friction velocity on the surface of steering gear 2 between the original model and two schemes under a blowing speed of 4 m/s. The blowing airflow changes the flow characteristics in the area of the steering gear, resulting in changes in the friction velocity on the surface of the steering gear. Table 3 provides the average increase in friction velocity on the surface of steering gear 2 components under the blowing airflow. It can be seen that the friction velocity of scheme 1 is larger than that of scheme 2. The friction velocity on each vibration damper is higher than that of the original model, which means that the snow particles on these components will bear greater shear forces, leading to unstable sedimentation of snow particles
