摘　　要：针对车轮的多边形磨损,建立了重载列车轨道三维耦合动力学模型,研究了机车车轮多边形磨损引起的轮轨动力相互作用。在动力学模型中嵌入了低粘着区(LAZ)和防滑控制算法,以分析在正常和低粘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。在两台不同磨损模式的机车上进行了对比试验,包括车轮周向磨损测量和机车振动试验,验证了模型的合理性。在此基础上分析了多边形磨损的动态响应,结果表明车轮多边形磨损不仅会加剧车轮/轨道的垂直力,还会加剧车轮与轨道之间的纵向相互作用。多边形磨损对机车前两轮对与后两轮对的纵向相互作用影响较大。A three-dimensional coupled dynamic model of heavy-duty train tracks was established to investigate the wheel rail dynamic interaction caused by polygonal wear of locomotive wheels.Low adhesion zone(LAZ)and anti-slip control algorithm were embedded in the dynamic model to analyze the impact of wheel polygon wear on the longitudinal and transverse interactions between wheel and rail under normal and low adhesion conditions.Comparative tests were conducted on two locomotives with dif⁃ferent wear modes,including wheel circumferential wear measurement and locomotive vibration test,to verify the rationality of the model.On this basis,the dynamic response of polygon wear was analyzed,and the results showed that wheel polygon wear not only exacerbates the vertical force of the wheel/rail,but also exacerbates the longitudinal interaction between the wheel and rail.Polygonal wear has a significant impact on the longitudinal interaction between the front two-wheel pairs and the rear twowheel pairs of the locomotive.
