车轮踏面
[铁路] wheel tread
- 它是通过测量列车在运行过程中车轮踏面与钢轨接触时产生的冲击载荷引起的钢轨形变来检测车轮踏面擦伤。
The principle of the project is that the wheel tread will generate the impact load that induce deformation of rail when the train running. - 建立自调节独立车轮走行部的运动方程，并采用踏面斜率的泰勒级数对重力复原力的表达式进行简化。
The dynamics equation of self-steering EEF bogie with TRW is derived and the gravity restoring force is expressed as Taylor's expansion of nonlinear tread gradient. - 因滑行使车轮踏面损伤，引起振动和噪声，为此要经常旋削车轮，从而缩短了使用寿命。
Sliding will result in the damage on the wheel tread, and cause vibration and noise as well. Therefore, the wheels should be often turned, and the service life is shortened.
