Description
Technical Field
The invention relates to a viscous damper containing a swingable umbrella-shaped blade, which is mainly applied to vibration control of a building structure and belongs to the technical field of structural vibration control.

Over the last several decades, extremely harmful earthquakes have occurred worldwide, causing enormous life, economic and property losses to society. At present, with the rapid development of economy, the damping technology of building structures is also continuously improved, more and more damping designs are applied to the building structures, and the damping designs also achieve good damping effect.
The earthquake-proof design of building structures is usually to add energy dissipation and shock absorption members at certain positions of the structure, or to arrange support members, connecting members and the like of the structure as the energy dissipation and shock absorption members. When an earthquake occurs, the energy dissipation and damping component can dissipate a part of energy through an energy dissipation mechanism of the energy dissipation and damping component, and damage to a main structure of a building is reduced or avoided. At present, in practical engineering application, the addition of a damper at an important position where a building structure may be largely deformed has become a mainstream vibration damping measure.
With the development of energy-consuming and vibration-damping technology, building design and scientific researchers have developed various dampers with different mechanisms, such as friction dampers, viscous dampers, metal dampers, and the like. The viscous damper has the characteristics of reliable energy consumption, convenient construction, safety and high efficiency, and is widely applied to building earthquake-resistant design. However, most building structure dampers at present often have better energy consumption capability under the action of large earthquake, and when medium and small earthquake acts on the structure, the energy consumption and vibration reduction capability of the damper is greatly limited due to smaller structural deformation. How to provide a safe and efficient viscous damper is a problem that needs to be solved by those skilled in the art.

Therefore, the damper has the characteristics of high energy consumption, safety and stability.
