The invention discloses a turbulent flow device for an inter-city train. The turbulent flow device comprises an inter-city train body, an equipment compartment, a liftable spoiler, a hydraulic lifting driving mechanism, a spoiler vortex generating device and a rotary stopper. The turbulent flow device can effectively guide the air flowing trend at the top of the train and disturb a tail air flow when the train normally runs so that boundary layer separation of the air flow flowing through the top of the train at the tail of the train is delayed, aerodynamic resistance borne by the train during running is reduced, and energy consumption needed by running of the train is decreased. Meanwhile, during braking, certain obstruction and disturbance are provided for the airflow at the tail of the train by lifting the turbulent flow device, the direct windward area of the spoiler is increased, and therefore running resistance except wheel rail adhesion and downward pressure used for strengthening the adhesion effect between wheel rails are provided for train braking; and therefore, the train can obtain a larger braking force during braking.

    本发明公开了一种城际列车用扰流装置,包括城际列车车体、设备舱、可升降式扰流板、液压升降驱动机构、扰流板涡流发生装置、回转止挡。本发明的扰流装置能有效引导列车顶部的空气流动趋势,在列车正常运行时对尾部气流进行扰流,从而延缓流经车顶气流在列车尾部所发生的附面层分离,从而降低列车运行所受到的气动阻力,并降低列车运行所需要的能耗,同时在制动时,通过抬升扰流装置对列车尾部的气流提供一定的阻碍与扰动,增大扰流板的直接迎风面积,从而为列车制动提供除轮轨黏着以外的运行阻力与用于加强轮轨之间黏着效应的下压力,从而使列车在制动时可以获得更大的制动力。
