Abstract

The invention relates to the field of drag reduction of rail trains, and provides a diversion device for equipment under rail trains and a rail train. The deflector for equipment under rail trains includes deflectors respectively arranged at the front and rear ends of the protective cabin for installing protective equipment along the traveling direction of the train, and the deflector is configured with a first deflector and the second A deflector is connected at an angle to a second deflector, the free end of the first deflector is connected to the vehicle floor, and an opening is formed between the first deflector and the second deflector toward the vehicle. A diversion groove that is downward and concave toward the top of the vehicle floor, and the diversion groove is used to direct the airflow blowing towards the protective equipment to the vehicle downward. The invention diverts the airflow blowing towards the protective cabin towards the ground, reduces the airflow directly flowing into the protective cabin, thereby reducing the direct impact of the airflow on the protective equipment, has a good drag reduction effect, and improves the aerodynamic resistance performance of the whole vehicle.

Description

technical field [0001] The invention relates to the technical field of rail train drag reduction, in particular to a flow guide device for rail train equipment and a rail train. Background technique [0002] Rail trains have a lot of equipment under the car, and they all bear the resistance from the airflow during the operation of the train, which is not conducive to the improvement of the speed of the rail train. For example, the bogie and the bogie cabin form a complex concave cavity structure, which is significantly disturbed by the ground effect, and the air flow is extremely complicated. The aerodynamic resistance in this area accounts for more than 25% of the whole vehicle resistance, which becomes the key issue of aerodynamic drag reduction of rail trains and the focus of aerodynamic optimization design. The current existing design schemes all have the problem of poor drag reduction effect. Contents of the invention [0003] The present invention aims to solve at ...
