The invention discloses an anti-drag self-adaptive vortex generator device for a high-speed railway vehicle. The anti-drag self-adaptive vortex generator device comprises a pressure sensor, a controller, a driving device, a lifting mechanism and a vortex generator, and the pressure sensor and the vortex generator are arranged at the tops of streamline parts of a head vehicle and a tail vehicle; the input end of the controller is in communication connection with the output end of the pressure sensor, and the output end of the controller is in communication connection with the driving device; the driving device directly drives the lifting mechanism; the lifting mechanism is fixedly connected with the vortex generator; when the train runs at a high speed, if pressure data monitored by the pressure sensor located at the streamline part of the tail train reaches a threshold value, the controller sends a signal to the driving device, and the lifting mechanism is driven to lift the vortex generator to the surface of the streamline part to implement resistance reduction. According to the anti-drag self-adaptive vortex generator device for the high-speed railway vehicle, the vortex generator is opened and closed in a self-adaptive mode, a tail vehicle airflow separation point is delayed to reduce aerodynamic resistance, and the purposes of saving energy and reducing consumption are achieved.
