Abstract

An axial vibration damping system for inhaul cables comprises vibration dampers, a vibration damping cable and a vibration damping cable sheath. The vibration damping cable is installed in the vibration damping cable sheath and can be freely telescopic in the vibration damping cable sheath; two ends of the vibration damping cable are both connected and provided with a vibration damper, or one endof the vibration damping cable is provided with a vibration damper while the other end has no vibration damper, and the end without a vibration damper is anchored with the inhaul cable or anchored onthe bridge fixed structure while the vibration damper is fixed on the anchor end of the inhaul cable system or the bridge fixed structure. The inhaul cable with the axial vibration damping system forinhaul cables comprises a vibration damping system and a cable system taking steel wires, steel strands or steel wire ropes as the cable body. The axial vibration damping system for inhaul cables is axially installed in the inhaul cable system. The manufacturing method for the system comprises the steps as follows: arranging the vibration damping cable sheath with the vibration damping cable in the cable body of the inhaul cable system to integrate with the cable body; arranging the vibration damper at one end or both ends of the vibration damping cable and arranging and fixing the vibration damper on the anchor end of the inhaul cable system or the bridge fixed structure. The system has good damping effect.

Description

Technical field:

[0001] The invention relates to a vibration damping system for a cable, a cable provided with the vibration damping system and a manufacturing method thereof. Background technique:

[0002] At present, when the cables of cable-stayed bridges are vibrated by the combined action of wind, wind and rain, and the vibration of the bridge body at home and abroad, the measures to reduce and suppress these vibrations include: making the original smooth-surfaced cable-stayed cables into spiral-shaped surfaces, Stay cables with striped convex and V-shaped grooves; use auxiliary cables to radially connect several stay cables; install rubber shock absorbers, hydraulic shock absorbers or friction shock absorbers at the ends of the stay cables Wait. However, it has been proved that the surface treatment of the stay cables is useful for suppressing and attenuating the vibration caused by the combined effect of wind and rain, but it is useless for the suppression and attenu...
