Vibration control device and method for slings of suspension bridge
The invention discloses a vibration control device and a vibration control method for slings of a suspension bridge. The vibration control device is arranged between the two abreast slings; one end of each sling is fixedly arranged on a main beam through a moving hinge; dampers are sequentially arranged along each sling; two ends of each damper are fixed with the corresponding sling through a sling clamp respectively. The vibration control method comprises the following steps: firstly, adjusting the frequency of one of the two abreast slings to achieve that the two slings are different in frequency; secondly, arranging a plurality of dampers between the two slings; finally, optimizing the mounting position of each damper according to the vibration mode control requirements of the slings. According to the device and the method, in-phase vibration generated by the double abreast slings is eliminated, and inverse phase vibration is restrained.
