摘要本文介绍了一种实时的铁路车轮磨损损伤控制系统的性能与不同的操作条件。特别是，在改变轮轨摩擦条件和不同的运行速度下的磨损增长率控制进行了调查。仿真结果表明，所设计的控制器能够有效地抑制机车在低速和中速加速过程中的质量损失，从而减小机车在直线轨道上运行时的轮对磨损。
ABSTRACT This paper presents the performance of a real-time rail–wheel wear damage control system with respect to different operation conditions. In particular, an investigation into the wear growth rate control under changing wheel–rail friction conditions and different operation speeds is performed. Simulation using a mathematical model considering longitudinal–vertical–pitch dynamics of a locomotive running on straight tracks shows that the proposed controller can effectively reduce the rail–wheel wear damage by limiting mass loss rate, particularly during acceleration under low and medium speeds.
