加速我国铁路运输现代化的主要任务,是提高列车运行速度和增加列车牵引重量。在高速、重载任务中,轮轨两个方面的一系列矛盾实际上是轮轨接触点上的各种技术问题。更确切地说,轮轨关系问题就是机车、车辆与轨道的使用、维修养护中的一个边缘科技问题 The main task of accelerating the modernization of China’s railway transportation is to increase the speed of trains and increase the weight of train trains. In the high-speed and heavy-duty tasks, a series of conflicts between two aspects of the wheel and rail are actually various technical problems at the wheel and rail contact points. More precisely, the issue of the relationship between the wheels and rails is the use of locomotives, vehicles and rails, and an edge technology issue in maintenance and maintenance
