Axle Yaw

• 释义.

  （车辆动力学）轴[车桥]横[左右]摆，车轴偏转（角）；

  轴负载；

To railway vehicles with bogie of non-common axle, not only rotating freedom of left and right wheel are independent, but also lateral and yaw motion are uncoupling. [无公用轴独立旋转车轮转向架的车辆不仅左右车轮的旋转自由度独立，而且两轮的横移和摇头也解耦。]
As concerning the factors determining the contact stress field of the rail, numerical examples show that the most important one is the axle load, the yaw angle is the second, and the lateral shift is the last. [文中的实例分析表明，轴载是影响钢轨接触应力的主要因素，摇头角的影响也不可忽视，相对说来横移量对钢轨接触应力的影响是最小的。]
