车轮多边形磨耗会影响轮轨系统零部件疲劳寿命和车辆乘坐舒适性,甚至威胁列车运行安全性。为研究车轮多边形激励下机车轴箱振动响应规律,文章联合多体动力学软件和有限元软件建立了考虑构架、轮对、轨枕、钢轨柔性的机车-轨道刚柔耦合动力学模型,采用实测机车轴箱振动加速度结果对模型进行验证,并研究了理想谐波和典型实测不规则车轮多边形对机车振动响应的影响。结果表明,当车轮多边形通过频率靠近轮轨P2共振频率或轮对固有模态频率时,会引起轴箱振动加速度幅值激增。轴箱振动加速度大小与车轮多边形阶次之间并不呈线性相关关系,而与多边形波深呈正相关关系。在实测不规则车轮多边形激励下,轴箱振动加速度的规律主要由车轮多边形的主导阶次决定。
Polygonal wear of wheels has a significant influence on the fatigue life of components in the wheel and rail system
as well as on the ride comfort and operational safety of trains. This paper investigates the vibration responses of locomotive axle boxes to the excitation of wheel polygons. To this end
a rigid-flexible coupling dynamics model was developed by combining multi-body dynamics software and finite element analysis software to simulate the locomotive-track system. This model incorporated the flexibility of bogie frames
wheelsets
sleepers
and rails. The measured vibration acceleration results of locomotive axle box were used to verify this model. This study further examined the effects of ideal harmonics and measured irregular wheel polygons in typical cases on vibration responses of locomotives. The findings show that the amplitude of axle box vibration accelerations increase significantly as the wheel polygon passing frequency approaches the resonant frequency of the wheel-rail system in the P2 mode or the wheelset frequency in its natural mode. The magnitude of axle box vibration accelerations exhibit a positive correlation with the depth of the polygon waveforms
rather than a linear correlation with the order of the wheel polygons. Furthermore
under the excitation of measured irregular wheel polygons
the dominant order of the wheel polygons is identified as the primary influencing factor on the axle box vibration accelerations.
