The invention relates to the field of resistance reduction of rail trains, and provides an under-train equipment flow guide device of a rail train and the rail train. The under-train equipment flow guide device of the rail train comprises flow guide covers which are arranged at the front end and the rear end of a protection cabin used for installing protection equipment in the running direction ofthe train. Each flow guide cover is provided with a first flow guide plate and a second flow guide plate connected with the first flow guide plate at an angle. The free end of each first flow guide plate is connected with a train bottom plate, a flow guide groove is formed between each first flow guide plate and the corresponding second flow guide plate, an opening of the flow guide groove facesthe lower portion of a train, the flow guide groove is concave towards the upper portion of the train bottom plate, and the flow guide groove is used for guiding airflow blown to the protection equipment to the lower portion of the train. Airflow blown to the protection cabin is guided to the ground, airflow directly flowing into the protection cabin is reduced, direct impact of the airflow on theprotection equipment is reduced, the drag reduction effect is good, and the aerodynamic resistance performance of the whole train is improved.
本发明涉及轨道列车减阻领域,提供轨道列车车下设备导流装置及轨道列车。该轨道列车车下设备导流装置包括沿列车的行驶方向分别设于用于安装防护设备的防护舱前后两端的导流罩,所述导流罩构造有第一导流板和与所述第一导流板呈角度连接的第二导流板,所述第一导流板的自由端与车底板连接,所述第一导流板与所述第二导流板之间形成开口朝向车下且向所述车底板上方内凹的导流槽,所述导流槽用于将吹向所述防护设备的气流导向车下。本发明将吹向防护舱的气流向地面方向引流,减少直接流入防护舱中的气流,从而降低气流对防护设备的直接冲击,减阻效果好,提高了整车气动阻力性能。
