The invention provides an active radial control method and system for a train. The control method comprises the following steps: S1, acquiring train running route information and train driving information; S2, calculating and generating an active radial control instruction according to the train running route information and the train running information; and S3, controlling a wheel set to be in a radial position according to the active radial control instruction. The control system comprises a signal acquisition device, an upper computer and a radial execution mechanism. According to the active radial control method for the train, the bogie has the good curve passing capacity, friction between wheel rails is reduced, the service life of the wheel rails is prolonged, whistling generated by wheel rail friction when the train passes through the curve is eliminated, and the radius of the curve where the train passes through is reduced. And the running stability, flexibility and safety of the train are improved.

    本发明提供一种列车主动径向控制方法及控制系统。该控制方法包括:S1、获取列车运行线路信息和列车行驶信息;S2、根据列车运行线路信息和列车行驶信息计算并生成主动径向控制指令;S3、根据主动径向控制指令控制轮对处于径向位置。该控制系统包括:信号采集装置,上位机和径向执行机构。本发明提供的一种列车主动径向控制方法,使得转向架具有较好的曲线通过能力,从而降低了轮轨之间的摩擦,延长了轮轨的使用寿命,消除了列车通过曲线时轮轨摩擦的啸叫声,减小了列车通过的曲线半径,提高了列车运行的稳定性、灵活性和安全性。
