Current situation and development of vibration and noise from rail trains

Sources of vibration and noise from rail trains are described in detail. Prediction methods ， measurement techniques， vibration and noise reduction technology and related standards are reviewed. Design of vibration and noise of track trains is a multi-disciplinary systems engineering. Insight into the mechanism of noise generation and sound contribution of each noise unit is the premise of vibration and noise control of rail trains. It is a necessary condition for managing all the characteristics of vibration and noise in systematic way ， and to establish a continuous quality management plan. In order to reduce rail train noise pollution ， it is a powerful guarantee to strengthen legislation and criterion for noise control and prediction.
