摘要 严重的车轮多边形磨损通常会引起剧烈的轮轨相互作用，威胁铁路车辆的运行安全。本文通过大量的现场试验和数值模拟，研究了重载机车车轮的多边形磨损对动态性能和轮轨相互作用的影响，其中特别关注机车振动和动态轮轨切向力。首先对两台客观机车的测量结果进行了比较，包括车轮多边形磨损特征以及机车垂直、纵向和横向振动的特征。然后制定了 3D 重载列车-轨道耦合动力学模型，以研究机车车轮多边形磨损引起的轮轨动态相互作用。将低附着区域（LAZ）和基于PI的防滑控制算法嵌入到动态模型中，分析正常和低附着条件下车轮多边形磨损对轮轨纵向和横向相互作用的影响。结果表明，严重的车轮多边形磨损不仅对轮轨系统的垂向性能产生显着影响，而且对轮轨系统的纵向性能也产生显着影响。车轮高阶多边形磨损对机车系统部件的纵向、横向和垂直振动影响显着。
ABSTRACT Serious wheel polygonal wear usually causes drastic wheel/rail interactions, which threats the running safety of railway vehicles. This paper presents an investigation into the effect of polygonal wear of heavy-haul locomotive wheels on the dynamic performance and wheel/rail interactions through extensive on-site tests and numerical simulations, in which a special attention is paid to locomotive vibrations and dynamic wheel/rail tangential forces. The measured results conducted on two objective locomotives were firstly compared, including the characteristics of wheel polygonal wear and locomotive vibrations in vertical, longitudinal and lateral directions. A 3D heavy-haul train-track coupled dynamic model was then formulated to investigate wheel/rail dynamic interaction induced by polygonal wear of locomotive wheels. A low adhesion zone (LAZ) and a PI-based anti-slip control algorithm were embedded into the dynamic model to analyse the effects of wheel polygonal wear on wheel/rail longitudinal and lateral interactions under normal and low adhesion conditions. The results show that the severe wheel polygonal wear affects not only the vertical but also the longitudinal performance of the wheel/rail system notably. The wheel high-order polygonal wear has a conspicuous effect on longitudinal, lateral and vertical vibrations of locomotive system components.
