wear limit meaning in Chinese

极限磨损
磨损极限

Kingpin wear limits commercial trailers and semitrailers
商用拖车和半拖车的转向主销的磨损极限
The paper puts forward that allowable vertical - wear limits of the 60kg / m - rail can be raised 5 mm , which has great economic value
在此基础上，对钢轨的磨耗限进行了初步探讨，认为60kg m轨的垂直磨耗限可以提高5mm ，具有相当大的经济价值。
Last , the reliability of 50kg / m - rail and 60kg / m - rail is calculated by using the method combing the mote - carlo imitation with the finite element method . on the basis of the calibration method , the objective reliability index of the steel rail is recommended , and the problems of the present standards of the rail - wear limits are pointed out , and then the rail - wear limits are discussed
最后，采用有限单元法与蒙特卡罗法相结合的方法对50kg m轨和60kg m轨的可靠度进行了计算，根据“校准法”的思想得到了钢轨目标可靠指标的建议值，指出了现行钢轨磨耗标准所存在的问题。
