Suspension bridge sling support type vibration reduction system
The invention discloses a suspension bridge sling support type vibration reduction system which comprises two subsystems including a damping vibration reduction system and a frequency modulation vibration reduction system. The support type vibration reduction system comprises a rigid support, a frequency modulation mass element, a threaded rod, viscous liquid, an elastic buffer box, a supporting spring, a base, a side plate, a rigid support branch, a spherical hinge and a support end plate. The multiple strands of slings are connected through the sling separator; a rigid support is connected with a sling separator through a support end plate and is in smooth transition to a rigid support branch, a threaded rod extends out of the branch to be provided with a frequency modulation mass element, and high-frequency vibration of a sling is controlled. The rigid support is fixed to a bottom plate of the elastic buffering box through a spherical hinge and rotates around the spherical hinge to dissipate energy. The box body is provided with a cover plate, so that internal viscous liquid is prevented from leaking out; the side plate is connected to the bracket and is immersed in the viscous liquid; the support spring provides additional stiffness for the rigid bracket. The wind-induced vibration of the sling can be effectively controlled, installation and maintenance are convenient, and the manufacturing cost is saved.
本发明公开了一种悬索桥吊索支架式减振系统，包括阻尼减振系统和调频减振系统两个子系统；支架式减振系统包括刚性支架、调频质量元件、螺纹杆、粘滞液体、弹性缓冲箱、支承弹簧、底座、侧板、刚性支架分支、球铰和支架端板；多股吊索通过吊索分隔器相连；刚性支架通过支架端板与吊索分隔器连接，平滑过渡到刚性支架分支，在分支上伸出螺纹杆安装调频质量元件，控制吊索的高频振动；刚性支架通过球铰固定于弹性缓冲箱底板，绕球铰旋转耗能；箱体设有盖板，防止内部的粘滞液体漏出；侧板连接在支架上并浸没于粘滞液体中；支承弹簧为刚性支架提供额外刚度。本发明能有效控制吊索风致振动，且便于安装和维护，节省制作成本。
