Combined disc type energy dissipation shock absorber

Abstract

The invention discloses a combined disc type energy dissipation shock absorber and belongs to the technical field of building shock absorption control. The combined disc type energy dissipation shock absorber comprises multiple sets of disc units which are sequentially opposite. Each set of disc unit comprises at least one fixed disc, at least one movable disc, a damping part and a drive part for driving the movable discs to rotate. The movable discs and the fixed discs are arranged oppositely, and rotary shafts are arranged between the middle portions of the movable discs and the middle portions of the fixed discs. The fixed discs are fixedly arranged, and the damping parts are connected between the fixed discs and the movable discs. The drive parts are arranged on the movable discs. The shock absorber has a displacement enlargement (regulation) function, the shock absorber can start to work and exert an energy dissipation effect under small displacement, meanwhile, it is guaranteed that the energy dissipation performance of the damping parts can be fully exerted, and a good shock absorption effect and a good economic effect are achieved.

Description

technical field [0001] The invention relates to the technical field of building vibration reduction control, in particular to a combined disc energy dissipation shock absorber. 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 shoc...

AI Technical Summary

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
