摘要
轨道车辆在运行过程中会产生不同类型的铁路噪声,主要包括弓网噪声、车辆自身各零部件振动及正常工作噪声以及轮轨噪声。主要针对城市有轨电车通过小半径曲线时产生的轮轨强噪声进行研究,意在了解该噪声产生的机理,定性地分析影响噪声大小的因素,提出合理控制噪声的方法,以达到降噪环保的目的。
Rail vehicles in the operation will produce different types of railway noise,mainly including the pantograph catenary noise,the vibration and the normal working noise from vehicle parts and components,and wheel rail noise.This paper mainly focuses on the research of the strong noise of the wheel/rail which is produced when the urban tram is running in small radius curve,and is intended to understand the mechanism of the noise generation.The qualitative analysis of the factors that affect the level of the noise is conducted,and the reasonable methods to control the noise are put forward,to achieve the purpose of noise reduction and environmental protection.
