摘要: 曲线啸叫噪声是城市轨道交通中一个亟待解决的问题,但目前国内对其研究较少。以70%低地板有轨电车通过嵌入式轨道小半径曲线时为研究对象,通过测试和分析,研究其轮轨啸叫噪声特性及产生机理。测试曲线半径分别是25 m和50 m,试验速度分别是3~9 km/h和4~20 km/h。试验过程中轮轨接触表面状态分别考虑了自然状态、水润滑状态、油润滑状态和固体润滑状态。测试结果表明,未润滑状态下的车外标准点噪声LAeq在56~91 dB(A),其中87%~92%的工况发生啸叫或轻微啸叫;导向轮对(第一位轮对)内侧车轮发出的啸叫噪声最为显著,其产生机理是轮轨间的横向蠕滑激励车轮1 811 Hz频率处(0,3)轴向模态振动,从而产生强烈的单频振动并发出啸叫。试验对比了不同润滑状态(水、润滑油、固体润滑剂)对啸叫的控制效果,测试结果表明采取润滑后,测试工况中发生啸叫或轻微啸叫的比例降低到19%~50%,车外噪声LAeq显著降低。研究补充了国内在有轨电车-嵌入式轨道曲线啸叫方面试验数据,并基于试验数据基本弄清了有轨电车-嵌入式轨道曲线啸叫噪声的产生机理。

Abstract: Curve squeal noise is an urgent problem to be solved in urban rail transit, however there is less research on it in China at present. Taking the 70% low-floor tram traversing the tight curves of embedded rail track as the research object, the characteristics and mechanisms of wheel/rail squeal are investigated by measurements and analyses. The radiuses of the measured curves are 25 m and 50 m, the velocities of the tram traversing the measured curves are 3~9 km/h and 4~20 km/h respectively. During the field test, the state of the wheel/rail contact surface is considered natural state, water lubrication, oil lubrication and solid lubrication respectively. Measured results show that the exterior noise LAeq is in the range of 56 to 91 dB(A), in which 87%~92% of the measurements occur curve squeal when not adopting lubrication; the squeal emitted by the inner wheel of the leading wheelset(the first wheelset) is the most significant, the mechanism is that the lateral creep between the wheel and rail excites the (0,3) axial wheel mode at 1 811 Hz so that the wheel vibrates significantly at the single frequency and squeals. The effects of different lubrication conditions (water, oil lubricant, solid lubricant) on controlling the squeal are also investigated. It is found that the percentage of the measurements occurring curve squeal or slight curve squeal reduces to 19% to 50%, and the exterior noise LAeq reduces significantly when adopting lubrication. The domestic measured data on the tram-embedded rail track curve squeal are supplemented with the research,, and based on the measured data, the mechanism of squel noise emitted by the tram is basically understood.

Key words: curve, embedded rail track, lubrication, squeal, tram
