The invention discloses an intelligent auxiliary bend steering vibration reduction system for a railway vehicle, which at least comprises a steering vibration damper mounted between a bogie and a vehicle body, a controller mounted on the vehicle body and a connecting cable between the steering vibration damper and the controller, and a displacement sensor is arranged in the steering vibration damper. The controller detects the displacement of each steering damper and then can detect and calculate the radius and direction of a vehicle running curve according to the arrangement mode of the vehicle and the running direction of the train, so that the working mode of the system is automatically adjusted, and an active thrust action mode, an active tension action mode or a passive damping action mode corresponding to each steering damper is output. Therefore, vibration is attenuated and comfort is provided when a vehicle travels through a straight road or a small curve, active acting force for assisting curve steering is provided when the vehicle travels through a large curve, the lateral action between a bogie rim and a rail is relieved, abrasion between the rim and the rail is reduced, and the traction performance of the vehicle is improved.
本发明公开了一种轨道车辆用智能辅助弯道转向的减振系统,组成至少包括安装在转向架与车体之间的转向减振器和安装于车体上的控制器及其转向减振器和控制器之间的连接线缆,转向减振器上内置了位移传感器,控制器通过检测每个转向减振器位移,再根据车辆布置方式及列车行驶方向可检测计算车辆行驶弯道半径及弯道方向,从而自动调整系统工作模式,输出各转向减振器对应处于主动推力作用模式、主动拉力作用模式或被动阻尼作用模式,从而改善车辆通过直道或小弯道行驶时衰减振动提供舒适性,通过大弯道行驶时提供辅助弯道转向主动作用力,用于减轻转向架轮缘与铁轨之间侧向作用,减少轮缘与铁轨磨耗,提升车辆牵引性能。
