摘要
用超声波传播仿真对轮轴接触压力引起的回波高度变化进行了定量评定,并用研究轮轴界面法向刚度变化的方法,试验研究了全尺寸轮对循环旋转弯曲时的回波高度变化。
The quantitative evaluation is made on the variation in echo depth due to the contact pressure with a wheel by simulation of uhrasonic propagation. Moreover, the echo depth variation during cyclic rotating bending in a full-size wheelset was investigated experimentally by studying variation in normal stiffness at the axle-wheel interface.
