Problems solved by technology

However, due to the lack of displacement amplification function, energy-dissipating shock absorbers commonly used in construction engineering, such as buckling-constrained support dampers and viscoelastic dampers, often cannot fully exert their energy dissipation performance under small trigger displacements, and it is difficult to achieve Ideal damping effect

Abstract

The invention discloses a disc-type energy-dissipating shock absorber, belonging to the technical field of building vibration damping. The absorber comprises a fixed disc, a movable disc, a damping part and a driving part for driving the movable disc to rotate. The movable disc and the fixed disc are oppositely arranged. A rotary shaft is arranged in the middle between the two. The fixed disc is fixed and the damping part is connected between the fixed disc and the movable disc. The driving part is arranged on the movable disc. The disc-type energy-dissipating shock absorber has following beneficial effects: a displacement amplification (adjusting) function is achieved such that the shock absorber can work at low displacement and exerts energy-dissipating effect; energy-dissipating performance of the damping part can be fully made use of; and vibration damping effect and economic effect are obtained.

Description

technical field [0001] The invention relates to the technical field of building vibration damping control, in particular to a disc energy dissipation damper. Background technique [0002] Buildings will inevitably suffer from external dynamic loads such as wind and earthquakes during their service. When the external dynamic load applied to the building reaches a certain intensity, the building will generate strong vibration, which not only seriously affects the normal function of the building, but also may threaten the safety of the building, causing catastrophic damage and collapse of the building. as a result of. [0003] Building energy dissipation and vibration reduction control technology is to reduce the dynamic response of buildings by setting energy dissipation shock absorbers in buildings to absorb and dissipate the vibration energy of buildings under the action of external dynamic loads. [0004] In fact, the work of the energy dissipation shock absorber requires...
