The invention discloses a turning control method for a railway vehicle, which comprises the following steps of: acquiring the radius and the direction of a vehicle running curve according to the arrangement mode of the vehicle and the running direction of the train, and switching the working modes of steering vibration absorbers, and judging the radius and the direction of the curve by detecting the displacement of each steering vibration absorber. When the radius of the curve is larger than a certain limit value, all the steering shock absorbers are controlled to be in a passive damping function, and the steering shock absorbers provide passive damping force between the bogie and the vehicle and are used for attenuating high-frequency vibration and low-frequency vibration between the bogie and the vehicle; when the radius of the curve is smaller than a certain limit value, according to the detected direction of the curve and the driving direction of the vehicle, each steering damper is controlled to be in a corresponding active thrust action mode or active tension action mode, and corresponding active action thrust or tension is provided between the bogie and the vehicle; lateral action between a bogie rim and a rail is relieved, and the traction performance of a vehicle is improved.

    本发明公开了一种轨道车辆转弯控制方法,根据车辆布置方式及列车行驶方向获取车辆行驶弯道半径和弯道方向,对转向减振器的工作模式进行切换,本发明通过检测各转向减振器自身位移进行弯道半径及弯道方向判断,当弯道半径大于某个限定值时,控制各转向减振器处于被动阻尼作用功能,转向减振器在转向架与车辆之间提供被动阻尼力,用于衰减转向架与车辆之间高、低频振动;当弯道半径小于某个限定值时,根据检测的弯道方向及车辆行驶方向,控制各转向减振器分别处于相应的主动推力作用模式或主动拉力作用模式,在转向架与车辆之间提供一个相应的主动作用推力或拉力,用于减轻转向架轮缘与铁轨之间侧向作用,提升车辆牵引性能。
