Description
Technical field
The present invention is a kind of device that is used for civil engineering structure antivibration (shake), especially a kind of high energy consumption reposition metal damper.
Background technology
Seismic forces and the wind power of shaking are the major control loads that building structure is born; also be to cause building structure that the principal element of destroying and collapsing takes place; force mechanism and the dynamic response of cognitive structure under the dynamic load effect exactly, and it is implemented reliable antivibration (shake) safeguard measure is the research topic of a frontier nature.The control of structure passive energy dissipation is a kind of novel antivibration (shake) mode, promptly utilizes the passive energy dissipation device to consume the external drive energy, alleviates the destruction of external drive to main structure to reach.Shake at present and the passive energy dissipation device of earthquake developmental research has viscoelastic damper, viscous fluid damper, metal damper, frcition damper, marmem damper, magnetic () rheological damper etc. at wind.Metal damper mainly comprises mild steel damper and lead damper, and it has easy to make, cheap advantageous characteristic.The mild steel damper hysteresis loop is full inadequately, and energy dissipation capacity is lower; Lead damper has stronger energy dissipation capacity, yet but it does not have recovery characteristic.This has seriously restricted metal damper in building vibration damping application in engineering.
Summary of the invention
Technical problem: the purpose of this invention is to provide a kind of power consumption cheap, easy to make metal damper that resets, this damper can not only provide very high energy-dissipating property, and possesses very strong recovery characteristic, possesses in vibration processes from spacing ability simultaneously.
Technical scheme: the power consumption of the present invention metal damper that resets connects steel plate, left spring, perfusion lead, rod iron, limited cap, interior steel pipe, outer steel pipe, spacing steel plate, right spring, the right steel plate that connects by a left side and forms; Interior steel pipe is arranged in outer steel pipe, interior steel pipe and outside to be provided with perfusion between the steel pipe in the cavity plumbous, along interior steel pipe and outside steel pipe radially be inserted with rod iron, be provided with limited cap in the rod iron two ends; At the left end of damper, a left side connect steel plate be connected in the left end of steel pipe, in left spring is enclosed within steel pipe outer and a left side connect steel plate and outside between the steel pipe; At the right-hand member of damper, spacing steel plate and interior steel pipe join, and the right steel plate that connects joins with outer steel pipe, be provided with right spring screw between the steel plate be provided with left fixing threaded hole on left side connection steel plate in spacing steel plate and right the connection, are provided with right fixing threaded hole on right side connection steel plate.
The power consumption metal damper that resets is added and is located at intercolumniation and supports, bean column node, deformable positions such as truss lower chord, when structure deforms because of vibration, high energy consumption reposition metal damper also produces distortion, at this moment, interior steel pipe and outer steel pipe produce relative deformation, steel pipe produced motion in rod iron was followed, in its motion and deformation process, rod iron pushes the diffusing a large amount of inputted vibration energy of lead loss on the one hand, rod iron produces very strong elastic restoring force on the other hand, offer the certain elastic stiffness of structure, the spring at damper two ends also produces very strong elastic restoring force simultaneously.When vibration caused excessive distortion, the limited cap of rod iron termination and the limiting plate of interior steel tube head were blocked, and have limited the excessive deformation of damper, guaranteed that damper does not destroy.
This shows that this power consumption metal damper that resets is stressed clear and definite, easy to make, has very strong energy dissipation capacity and reset capability, can reduce the vibration reaction of civil engineering structure effectively.
Beneficial effect: the power consumption of the present invention metal damper that resets has the advantage of simple structure, easy to make, cheap, easy construction, it not only has very strong energy dissipation capacity, and possess very strong recovery characteristic, in vibration processes, possess from spacing ability simultaneously.It can be widely used in the wind resistance and earthquake-proof construction of civil engineering structures such as highrise building, bridge construction and tower mast structure.
