Catwalk damping system, catwalk and catwalk vibration reduction method
The invention discloses a catwalk damping system, a catwalk and a catwalk vibration reduction method, and relates to the technical field of bridge construction vibration control, on one hand, the catwalk damping system comprises at least one vertical damping device used for being arranged on a bearing cable and/or at least one horizontal damping device used for being arranged on a horizontal vibration control cable, the vertical damping device comprises a shell, damping liquid, a connecting piece, a mass block and a steel strand. On the second aspect, the catwalk comprises at least two bearing cables arranged at intervals in the transverse bridge direction, at least one horizontal vibration control cable connected between the two adjacent bearing cables and the catwalk damping system; the invention further provides a catwalk vibration reduction method implemented through the catwalk damping system. The horizontal damping device and/or the vertical damping device are/is mounted on the horizontal vibration control cable and the bearing cable according to the vibration modal displacement, so that the separation of horizontal vibration control and vertical vibration control of the catwalk is realized, the vibration of the catwalk is accurately controlled, and the damping characteristic and the vibration resistance of the catwalk and the safety and comfort of construction on the catwalk are improved.
本发明公开了一种猫道阻尼系统、猫道和猫道减振方法，涉及桥梁施工振动控制技术领域，第一方面，该系统包括至少一个用于设在承重索上的竖向阻尼装置和/或至少一个用于设在水平制振索上水平阻尼装置，竖向阻尼装置包括壳体、阻尼液、连接件、质量块和钢绞线。第二方面，该猫道包括至少两个横桥向间隔设置的承重索和连接在相邻两个承重索之间的至少一个水平制振索及上述猫道阻尼系统；第三方面还包括利用上述猫道阻尼系统实施的猫道减振方法。通过在水平制振索和承重索上，根据振动模态位移来安装水平阻尼装置和/或竖向阻尼装置，实现猫道水平振动控制和竖向振动控制分离，准确控制猫道振动，提高了猫道的阻尼特性、抗振性能和在猫道上施工的安全舒适性。
