Plate-type ballastless track multi-dimensional vibration isolation and reduction device and vibration reduction method thereof
The invention relates to a plate-type ballastless track multi-dimensional vibration isolation and reduction device and vibration reduction method thereof. The device comprises an upper end cover, an annular vibration reduction pad, a viscous-elastic material block and a base. The annular vibration reduction pad isolates and weakens the vibration effect in the horizontal direction. When a train load is small, the first pressing cylinder of the upper end cover extrudes a belleville spring set, a second pressing cylinder below the annular vibration reduction pad extrudes an outer viscoelastic material block, and the belleville spring set and the outer viscoelastic material block isolate and weaken vibration in the vertical direction together. When the train load is large, the center pressingshaft of the upper end cover makes contact with and extrudes the inner viscoelastic material block, the inner viscoelastic material block participates in work, the work performance of the vibration isolation and reduction device is improved, and meanwhile the limiting step is arranged on the base to limit the vertical displacement of the plate-type ballastless track. The vibration isolation and reduction effects can be achieved in the vertical direction and the horizontal direction at the same time, and it is guaranteed that good working performance is achieved under the action of different train loads.
本发明涉及一种板式无砟轨道多维隔减振装置及其减振方法，装置包括上端盖、环形减振垫、粘弹性材料块和底座。环形减振垫对水平方向的振动作用进行隔离和减弱。列车荷载较小时，上端盖的第一压筒挤压碟形弹簧组，环形减振垫下方的第二压筒挤压外粘弹性材料块，碟形弹簧组和外粘弹性材料块共同对竖直方向的振动进行隔离和减弱。列车荷载较大时，上端盖的中心压轴接触并挤压内粘弹性材料块，内粘弹性材料块参与工作，提高隔减振装置工作性能，同时底座上设置限位台阶对板式无砟轨道的竖向位移进行限制。本发明能够在竖直和水平方向上同时发挥隔减振作用，保证在不同的列车荷载作用下均具有良好的工作性能。
