Abstract
A railway vehicle with an aerodynamic lift control device is disclosed. An equipment compartment is formed between a vehicle body bottom plate at the bottom of a vehicle body and a passenger room floor, and the aerodynamic lift control device is provided in the equipment compartment; the aerodynamic lift control device comprises an aerodynamic lift regulation fan and aerodynamic lift air ducts, and an aerodynamic lift regulation air port located within the aerodynamic lift control range is formed in the vehicle body bottom plate; one end of each aerodynamic lift regulating air duct communicates with the aerodynamic lift regulation air port, and the other end communicates with the aerodynamic lift regulating fan; and the aerodynamic lift regulation fan changes the pressure distribution form of the bottom of the train by blowing positive pressure airflow or sucking negative pressure airflow.
