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.

    本发明公开了一种减阻的高速轨道车辆自适应涡流发生器装置,包括压力传感器、控制器、驱动装置、升降机构、涡流发生器,压力传感器和涡流发生器均设置于头、尾车流线型部位顶部;控制器的输入端与压力传感器的输出端通信连接,控制器的输出端与驱动装置通信连接;驱动装置直接驱动升降机构,升降机构与涡流发生器固定连接;当列车高速运行时,若位于尾车流线型部位的压力传感器监测的压力数据达到阈值,控制器发出信号至驱动装置,驱动升降机构升起涡流发生器至流线型部位表面实施减阻。本发明一种减阻的高速轨道车辆自适应涡流发生器装置通过自适应开闭涡流发生器,延后尾车气流分离点以减小气动阻力,达到节能降耗的目的。
