The invention belongs to the field of high-speed noise reduction, and discloses a noise reduction method for a high-speed train, which greatly shields high-speed airflow blown to a pantograph, so that pneumatic noise of the high-speed train is greatly reduced, and a drainage channel is arranged near the pantograph in the advancing direction of the high-speed train, so that the pneumatic noise of the high-speed train is greatly reduced. The drainage channel extends in the advancing direction of the high-speed train and changes the flow direction of airflow blowing to the pantograph, so that the flow direction path of the airflow deviates from the pantograph. The invention further discloses a flow guide unit based on the noise reduction method for the high-speed train. The flow guide unit is arranged on the top face of the high-speed train.

    本发明属于高速降噪领域,公开了一种用于高速列车的降噪方法,极大地屏蔽了吹向受电弓的高速气流,从而使得高速列车的气动噪音极大地降低,其沿高速列车的行进方向在受电弓的近旁设置引流通道,引流通道沿高速列车的行进方向延伸,引流通道改变吹向受电弓的气流流向,使得其流向路径偏离受电弓。本发明还公开了一种基于上述用于高速列车的降噪方法的导流单元,设置在高速列车的顶面。
