The invention discloses a control device for reducing a resistance and a noise of a high-speed train. The high-speed train comprises bogies arranged at the bottom of each carriage, at least one windward side of each bogie is provided with a diversion trench recessed towards one side of the roof of the high-speed train in the axis direction of the high-speed train, an interval between the diversion trench and each bogie is within a preset range, the diversion trench is at least provided with a first inclined surface, a first included angle is formed between the first inclined surface and the plane where the bottom of the carriage is located, and the first included angle is an acute angle. By means of the flow field control mode that the diversion trench is formed in front of each bogie of the high-speed train, interference control over the bogie and a surrounding area flow field is achieved, resistance reduction and noise reduction of the whole high-speed train are achieved, train energy consumption is reduced, and the environment friendliness of the train is improved.

    本发明公开了一种高速列车减阻降噪的控制装置,所述高速列车包括设置在每节车厢底部的转向架,沿所述高速列车的轴线方向上,所述转向架的至少迎风一侧设有向所述高速列车车顶一侧凹陷的导流槽,所述导流槽与所述转向架之间的间隔在预设范围内,所述导流槽至少具有第一斜面,所述第一斜面与所述车厢底部所在平面具有第一夹角,所述第一夹角为锐角。本发明利用在高速列车转向架前设置导流槽的流场控制方式,实现对转向架及周围区域流场的干扰控制,实现高速列车整车减阻和减噪,降低列车能耗,提高列车的环境友好性。
