The invention relates to the technical field of high-speed train vehicle equipment and aerodynamic noise control, and provides a high-speed train cowcatcher which comprises a cowcatcher body, the cowcatcher body is of a flat streamline structure, the end, close to a bogie cabin, of the cowcatcher body is the rear end and is provided with an active jet flow module used for increasing three-dimensional disturbance to airflow, and the active jet flow module is provided with a jet flow control module. And the other end of the cowcatcher body is a windward side. Compared with the prior art, the active jet flow module is arranged, three-dimensional disturbance can be effectively increased for air flow through the multiple jet flow openings, and therefore excitation of the air flow to the acoustic mode in the bogie cabin is reduced, and the peak value of the top of the bogie cabin, the peak value of the rear wall and the broadband aerodynamic noise amplitude are effectively reduced.

    本发明涉及高速列车车辆装备技术与气动噪声控制技术领域,提供一种高速列车排障器,包括排障器本体,所述排障器本体为扁平流线型结构,排障器本体靠近转向架舱的一端为后端,设置有用于给气流增加三维扰动的主动射流模块,排障器本体的另一端为迎风面。与现有技术相比,本发明具有主动射流模块,通过多个射流口可以有效对气流增加三维扰动,从而降低气流对转向架舱内部声模态的激励,有效降低了转向架舱顶部的峰值、后壁的峰值及宽频气动噪声幅值。
