Multi-strand sling damping device and multi-strand sling for suspension bridge
The multi-strand sling damping device comprises a rigid rod piece, an eddy current energy consumption device is fixedly installed on the rigid rod piece, and the eddy current energy consumption device comprises a metal plate arranged in the axial direction of the rigid rod piece and a sliding block installed in the axial direction of the rigid rod piece in a swinging mode. And a permanent magnet is arranged on the sliding block. Each rope strand of the multi-rope-strand sling is connected with one damping device, one end of the rigid rod piece of the damping device of one rope strand is fixedly connected with the rope strand, the other end of the rigid rod piece of the damping device of the other rope strand is connected with the sliding block of the damping device connected with the other rope strand, and the damping devices of the rope strands are sequentially connected into a ring shape. The damping device for the multi-strand sling allows limited small-amplitude movement between the strands, and the limited small-amplitude movement does not enable the whole multi-strand sling to generate large-amplitude vibration.
本发明公开了一种多索股吊索减振装置及悬索桥用多索股吊索，其包括刚性杆件，所述刚性杆件上固定安装电涡流耗能装置，所述电涡流耗能装置包括沿刚性杆件轴向布置的金属板、沿刚性杆件轴向摆动安装的滑块，所述滑块上布置永磁铁。多索股吊索的各索股分别连接一个所述减振装置，且一根索股的减振装置的刚性杆件的一端与该索股固定连接，另一端与另一根索股连接的减振装置的滑块连接，使各所述索股的所述减振装置依次连接成环状。本发明多索股吊索减振装置允许索股之间进行有限制的小幅运动，且这种有限制的小幅运动不会使多索股吊索发生整体的大幅振动。
