Abstract

The invention relates to a built-in damping vibration attenuation device. The built-in damping vibration attenuation device comprises a connecting cylinder and a damping set; the connecting cylinder is internally provided with a containing area used for containing a clamp for clamping a vibration attenuation target; the damping set is arranged in the connecting cylinder and comprises two hydraulic dampers, the two hydraulic dampers of the damping set are symmetrically arranged on the two sides of the containing area, cylinder barrels of the two hydraulic dampers contained in the damping set communicate with each other through a guide pipe, and piston rods of the hydraulic dampers are used for abutting against the clamp. Interconnection of the two opposite hydraulic dampers is achieved through the guide pipe, so that hydraulic inerter between the two hydraulic dampers of the damping set is achieved, negative rigidity is provided for the structure through the hydraulic inerter, and the vibration control effect of the structure can be greatly improved.

Description

technical field [0001] The present application relates to the technical field of structural vibration control, in particular to a built-in damping and vibration reduction device. Background technique [0002] With the continuous increase of the span of cable-stayed bridges and the length of cables, the problem of dynamic load response of cable-stayed cables has become increasingly prominent. As the main load-bearing components of cable-stayed bridges, cable-stayed cables are prone to large vibrations under the excitation of dynamic loads such as wind loads and traffic loads due to their characteristics of large flexibility, light weight, and low damping. The continuous shaking of the cables will not only lead to the fatigue damage of the cables and their auxiliary structures, causing hidden dangers to the safety structure of the bridge, but also cause discomfort and insecurity for passing pedestrians and vehicles, affecting the normal operation of the bridge. [0003] In th...
