Description
Technical Field
The utility model relates to a damper structure, in particular to a self-adaptive damper.
Background
A damper is a device for providing resistance to movement and consuming movement energy. A wide variety of dampers (or shock absorbers) have long been used in the aerospace, aviation, military, firearms, automotive, and other industries to dampen vibration and dissipate energy.
The hydraulic damper is a vibration control device sensitive to speed response;
the hydraulic damper is mainly suitable for vibration resistance of pipelines and equipment in nuclear power plants, thermal power plants, chemical plants, steel plants and the like. The vibration of the pipe system which is commonly used for controlling the impact fluid vibration (such as the impact disturbance of main valve quick closing, safety valve discharging, water hammer, pipe breaking and the like) and the earthquake disturbance;
the vibration problem of high-speed rotating machines is a relatively prominent and difficult problem to solve. The rotational speeds of such machines are high and operate above critical or even orders of critical rotational speeds. In order to ensure safe operation thereof, dampers are therefore often used to reduce vibrations in addition to careful design and accurate manufacturing installation. Squeeze film dampers and spring dampers are two commonly used types of dampers. A new combined adaptive damper is designed herein.
The liquid damper can not effectively control the vibration of low amplitude high frequency or high amplitude low frequency, the spring damper is suitable for the occasions, and the same occasions are suitable for the liquid damper but not suitable for the spring damper, so the damper combining the advantages of the liquid damper and the spring damper is urgently needed in the market
Disclosure of Invention
In order to overcome the defects of the prior art, the utility model provides the self-adaptive damper, which can integrate various advantages of the spring damper and the hydraulic damper.
