Title:
空力揚力制御装置を有する鉄道車両
Document Type and Number:
Japanese Patent JP7260720
Kind Code:
B2
Abstract:
A railway vehicle with an aerodynamic lift control device. 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. According to the railway vehicle, the bottom pressure distribution of the train is improved by installing the bottom air blowing and sucking device according to the characteristics of the bottom flow field of the train, so that active and accurate control of aerodynamic lift borne by the train is realized.
