高速铁路轮轨噪声及其控制措施

高速铁路的发展,列车速度的提高使铁路噪声污染也急剧增加,不可避免地对人类生活带来了极大的负面影响,因此,发展高速铁路必须考虑噪声问题。笔者从噪声对人类产生的负面影响入手,分析了高速铁路噪声产生的原理,论述了轮轨噪声的组成及各组成部分对轮轨噪声的贡献程度。结合铁路噪声的评价指标,借鉴国内外相关经验,分别从轨道结构和车辆两方面详细阐述了控制轮轨噪声的措施。并总结了为了控制轮轨噪声,今后应重点发展的方向和重视的问题,对降低高速铁路轮轨噪声具有一定的指导意义。

Wheel/Rail Noise on High Speed Railway and Its Control Measures

With the development of high speed railway,rail noise becomes crucial and will inevitably bring negative impact on people's life.Therefore,noise problem must be taken into consideration when developing the high speed railway. Starting from the negative impact of noise on mankind,how the noise is produced is analyzed;the composition of wheel/rail noise and the contribution of each component to the wheel/rail noise are discussed.Referring to the experience from both home and abroad,combining the evaluation index of wheel/rail noise,the control measures are described in detail from both rail structure and vehicle.The development priority and problems need to be emphasized in future for the control measures are summarized,which could be taken as the guide in reducing the rail/wheel noise.
