本文研究了轮对-轨道系统摩擦振动与曲线半径的关系，并从摩擦振动的观点解释了钢轨弯曲的普遍现象。地铁线路脱轨的典型现象是，脱轨一般发生在曲线半径较小的情况下，而曲线半径较大或直线轨道上的脱轨则很少发生。分别建立了车辆-轨道系统的多体模型和不同曲线半径的多轮对-轨道系统的有限元模型。根据蠕变力分析和不稳定振动分析，可以识别蠕变力和摩擦诱导振动之间的相关性。总结了轨道曲线半径对轮对-轨道系统摩擦振动的影响，并对典型的轮对-轨道系统摩擦振动现象进行了解释。
The purpose of this article is to investigate the correlation between the friction-induced oscillation of a wheelset-track system and curve radius and to explain a general phenomenon of rail corrugation based on the viewpoint of friction-induced oscillation. The typical phenomenon of rail corrugation in metros is that corrugation generally arises when the curve radius is quite small, whereas it rarely occurs when the curve radius is larger or on a straight track. Different multibody models of the vehicle-track system and finite-element models of the multiple-wheelset-track system with different curve radii are established, respectively. According to the creep force analyses and unstable vibration analyses, the correlation between the creep force and friction-induced oscillation can be identified. Then the effect of the track curve radius on the friction-induced oscillation of the wheelset-track system can be summarized, which provides an explanation of the typical phenomenon of corrugation.
