Abstract

A multidimensional shape memory alloy energy consumption damper comprises a central rotary shaft, a rigid plate, a cubic shell, an adjusting nut and a shape memory alloy wire. The central rotary shaft, the shape memory alloy wire and the rigid plate are located in the shell. The central rotary shaft penetrates the center of the shell, is connected with the rigid plate, and jointly rotates and translates with the rigid plate. The shape memory alloy wire is connected with the edge of the rigid plate and the shell in multiple directions and fixed by the adjusting nut after being anchored. When the rotary shaft translates or rotates relative to the shell, the rigid plate drives the shape memory alloy wire to deform so as to absorb energy, consume energy and reduce vibration. The multidimensional shape memory alloy energy consumption damper is simple, economical, and easy to implement.

Description

Multidimensional shape memory alloy energy consumption damper
Technical field
The present invention relates to engineering structures antidetonation wind resistance technical field, specifically finger-type shape memory alloys energy-consumption damper.
Background technology
In recent years, structural vibration control has become one of the most popular damping technology in earthquake resistant engineering wind resistance field.Due to its practicality and validity, receive increasing concern.
Structural vibration control is divided into ACTIVE CONTROL, semi-active control, Passive Control and Hybrid mode usually.Wherein, damper forms as the core of control technology the enforcement directly affecting control technology.ACTIVE CONTROL utilizes extra power to provide control to reduce the reaction of structure under environmental load effect, although its control effects is remarkable, need to input external energy, and it is higher to arrange technical requirements to controller, expense is comparatively large, and engineer applied is comparatively difficult.Passive Control does not then need extra power, cheap, is easy to realize and application, and possesses good effectiveness in vibration suppression.
Summary of the invention
The object of this invention is to provide a kind of multidimensional shape memory alloy energy consumption damper, this damper can reduce the dynamic respons of structure under environmental load effect, improves Building Structural Safety energy.
Above-mentioned purpose of the present invention realizes by following technical solution:
Multidimensional shape memory alloy energy consumption damper, be made up of rigid slab, shape-memory alloy wire, shell, adjusting nut and central rotating shaft, shell is cube, central rotating shaft is horizontal through the center of shell, central rotating shaft and both sides shell leave gap and conveniently rotate, and shell is stretched out at the two ends of central rotating shaft; Rectangle rigid slab is horizontally fixed on the centre of rotating shaft, and position is in the center of enclosure, and the long limit of rigid slab is perpendicular to rotating shaft; The corner shape-memory alloy wire of rigid slab is fixed on shell from upper and lower and the left and right four direction parallel with central rotating shaft; The fixed point of shell is provided with adjusting nut.
Rigid slab, shell and central rotating shaft can be made up of steel.
Shape-memory alloy wire can adopt intellectual material to make.
When shell and central rotating shaft generation relative translational movement or when rotating, rigid slab can drive shape-memory alloy wire to be out of shape, thus plays the effect absorbing energy, passive energy dissipation.
The present invention stretches to consume energy by shape-memory alloy wire and reduces place structural vibration reaction, improves structural safety performance.Compared with prior art, feature of the present invention is: can conveniently regulate antitorque damping by changing rigid slab size.Conveniently can carry out prestretched to shape-memory alloy wire by adjusting nut, thus change damper energy-dissipating property, adapt to various operating mode.The present invention can provide the damping in rotation and translation direction, and designs and produces simple, low cost, and it will be widely used in engineering structures antidetonation and wind resistance technical field.There is the advantages such as simple, economic, easy to implement.

In figure: 1. central rotating shaft; 2. rigid slab; 3. shape-memory alloy wire; 4. shell; 5. adjusting nut.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in detail:
Multidimensional shape memory alloy energy consumption damper, be made up of central rotating shaft 1, rigid slab 2, shape-memory alloy wire 3, shell 4 and adjusting nut 5, shell 4 is cube, central rotating shaft 1 is horizontal through the center of shell 4, central rotating shaft 1 and both sides shell leave gap and conveniently rotate, and shell 4 is stretched out at the two ends of central rotating shaft 1; Rectangle rigid slab 2 is horizontally fixed on the centre of rotating shaft 1, and position is in the center of shell 4 inside, and the long limit of rigid slab 2 is perpendicular to rotating shaft 1; The corner shape-memory alloy wire 3 of rigid slab 2 is fixed on shell 4 from upper and lower and the left and right four direction parallel with central rotating shaft 1; The fixed point of shell 4 is provided with adjusting nut 5.
Central rotating shaft 1, rigid slab 2 and shell 4 are made up of steel.
In use procedure, by shell 4 with under being axially fixed in beam, central rotating shaft 1 two ends are fixed on the support that is connected with lower floor, central rotating shaft 1 will be made to move relative to shell 4 when levels produces relative displacement under load action, thus drive shape-memory alloy wire 3 to be out of shape, reach power consumption object.
