The invention relates to an active control damping device and method for secondary suspension of a railway vehicle, and the device comprises a signal collection system which is used for collecting a real-time vibration acceleration signal of a vehicle body of the railway vehicle in real time, and obtaining a corresponding index value through a signal processor; the control system comprises a controller installed on the vehicle body and an actuator connected with the controller and installed at the bottom of the vehicle body, and the controller calculates main power needing to be applied according to index values and controls the actuator to further change transverse damping force and vertical damping force output by the vibration reduction system; the vibration reduction system comprises a transverse damper and a vertical damper which are hinged to the actuator and the bogie frame respectively. Compared with the prior art, the damping device has the advantages that the acting force direction is more flexible, the control effect is better, the vehicle running stability and riding comfort are improved, and the damping effect is obvious.
本发明涉及一种用于轨道车辆二系悬挂的主动控制减振装置及方法,该装置包括:信号采集系统:用以实时采集轨道车辆车体的实时振动加速度信号,并通过信号处理器获取对应的指标数值;控制系统:包括安装在车体上的控制器以及与控制器连接且安装在车体底部的作动器,控制器根据指标数值计算所需施加的主动力,并控制作动器进而改变减振系统输出的横向阻尼力和垂向阻尼力;减振系统:包括分别与作动器和转向架构架分别铰接的横向阻尼器和垂向阻尼器。与现有技术相比,本发明具有作用力方向更加灵活、控制效果更佳、提高车辆运行平稳性和乘坐舒适性、减振效果明显等优点。
