The invention provides a sinking type pantograph basin flow guide and resistance reduction structure and a high-speed train, and relates to the field of railway vehicles, and the sinking type pantograph basin flow guide and resistance reduction structure comprises a pantograph basin formed by downwards sinking the top wall of the train; the drag reduction unit comprises a flow channel inlet and a flow channel outlet, the flow channel inlet is formed in the rear side wall of the bow basin, the flow channel outlet is formed in the top wall of the train at the downstream of the bow basin, a drag reduction flow channel is communicated between the flow channel inlet and the flow channel outlet, and the drag reduction flow channel is communicated with the flow channel outlet. The top wall and the bottom wall of the anti-drag flow channel are formed by double-Boltzmann function fitting, the problem that the resistance of the pantograph basin is increased due to high-speed airflow impact can be relieved, and under the condition that the overall layout of a pantograph system and the smoothness characteristic of a vehicle body do not need to be changed, the resistance of the pantograph basin is reduced. The resistance reduction unit can greatly reduce the resistance of the pantograph system and the whole vehicle, and is beneficial to improving the resistance reduction and noise reduction level of a higher-speed train.
本发明提供了一种下沉式受电弓弓盆导流减阻结构及高速列车,涉及轨道车辆领域,包括:弓盆,由列车顶壁向下凹陷形成;至少一条减阻单元,减阻单元包括流道入口和流道出口,所述流道入口设置在所述弓盆的后侧壁,所述流道出口设置在弓盆下游的列车顶壁上,所述流道入口和所述流道出口之间连通有减阻流道,所述减阻流道的顶壁和底壁分别由双玻尔兹曼函数拟合而成,本申请能缓解弓盆自身因高速气流冲击带来阻力增大的问题,在不需要改变受电弓系统整体布局以及车体平顺化特点的情况下,减阻单元能够大幅降低受电弓系统及整车阻力,有助于提升更高速列车减阻降噪水平。
