Netted stay cable vibration damping device
The invention discloses a netted stay cable vibration damping device which comprises M groups of vibration dampers. The vibration dampers are uniformly arranged on the same stay bridge cable surface, and each group of vibration dampers comprises N vibration dampers which are arranged on the same straight line; the stay bridge cable surface comprises a cable surface, the cable surface is formed by 2N stay cables, and the 2N stay cables are arranged between a main beam of a stay bridge and cable towers in a connected manner and are parallel to one another; the M groups of vibration dampers are radially arranged and form a netted stay cable vibration damping system; the 2N stay cables are divided into N groups from top to bottom, each group of stay cables comprises two stay cables which are vertically adjacent to each other, and the N vibration dampers of each group of vibration dampers are respectively connected onto the N groups of stay cables; the vibration dampers comprise lock chains and elastic outer sleeve columns, the elastic outer sleeve columns cover the lock chains, two ends of each lock chain extend to the outer side of the corresponding elastic outer sleeve column, and two buckle devices which are clamped on the corresponding stay cables are arranged at the two ends of each lock chain. The netted stay cable vibration damping device has the advantages that the netted stay cable vibration damping device is simple in structure, reasonable in design and convenient to construct, good service effects can be realized, and vibration of the stay cables can be effectively weakened.
