Description
Technical field
The present invention relates to a kind of Self-resetting marmem-compound energy-consumption damper of extrusion pressing type lead, suitable for engineering knot
The vibration damping control of structure, belongs to field of civil engineering.
Background technology
Engineering structure system can all produce response when by the interference or excitation in the external world, because excitation obtains system
Obtained the input of energy.Meanwhile the energy of input is changed into heat energy or other form of energy by system and can by certain mechanism
And consume, input energy and consume energy is kept balance.The ability of this system consume energy is referred to as damping.To huge
For civil engineering structure, Extraneous vibrations and unreliable are resisted by the damping energy dissipation characteristic of itself.As New Damping consumes energy
The continuous proposition of technology, add outer member using structure or the internal mode for adding element realizes structural vibration control mode all
Embody preferable control effect.

Embodiment
Below in conjunction with accompanying drawing and technical scheme, embodiment of the invention is further illustrated.
A kind of Self-resetting marmem-compound energy-consumption damper of extrusion pressing type lead, including front shroud 12, back shroud 17,
Zola's plate 15, right pulling plate 9, fixed plate 7, prestressed adjusted plate 3, inner cylinder 6, outer barrel 2, pull bar 11, marmem (SMA)
Silk 5, marmem (SMA) spring 13 and built-in lead 16, four groups of SMA silks 5 sequentially pass through prestressed adjusted plate 3, a left side
Arm-tie 15, fixed plate 7 and right pulling plate 9, prestressed adjusted plate 3, Zola's plate 15, fixed plate 7 and right pulling plate 9 are loop configuration,
SMA silks 5 are distributed in the central cavity formed between outer barrel and inner cylinder, and its both ends is strained and fixed with fixture 4 respectively；Zola's plate 15
Outside sets prestressed adjusted plate 3, changes the distance between prestressed adjusted plate 3 and Zola's plate 15 by regulating bolt 14, and then
Adjust the initial strain of SMA silks 5；The inner ring of ring-type fixing plate 7 and inner cylinder 6 are welded, and its outer shroud is connected by fixing bolt 8 and outer barrel 2
Connect；Pull bar 11 is cylinder type, and its one end and middle part are provided with transverse ring baffles, welded on the inner cylinder of two transverse baffles middle part
There is triangle rigidity hampering plate；The inner side of inner cylinder 6 is provided with multiple longitudinal baffles, and groove, groove and push-and-pull are formed between two longitudinal baffles
Triangle rigidity hampering plate on bar 11 is corresponding, and extruding lead 16 makes rigidity hinder a part directly in inner cylinder groove 18
Lead is absorbed in, mutually extruding occurs during to move；The front and rear cavity that outer barrel 2 is formed with inner cylinder 6 installs SMA springs 13 respectively,
Wherein, the SMA springs 13 in preceding cavity, which pass through, is welded on spring guide 10 on front shroud 12, the SMA springs 13 in rear cavity
Through pull bar 11；Front shroud 12, back shroud 17 and connecting rod 1 are connected by bolt with outer barrel 2, and pull bar 11 passes through back shroud
17。
When relative displacement occurs for pull bar 11 and connecting rod 1, because inner cylinder 6 is fixed in outer barrel 2, simultaneously because push-and-pull
The end of bar 11 and the limitation of middle barrier, the athletic meeting of Zola's plate 15 and right pulling plate 9 are restricted, therefore left and right arm-tie can produce
Relative displacement, the SMA silks 5 in pretensioned state for now connecting them continue tension, therefore pull bar 11 is either pressurized
Power or pulling force, all under tensions of SMA silks 5 act on, while left and right sides SMA springs 13 are provided restoring force by the effect of power, interior
Cylinder 6 produces relative displacement with pull bar 11, causes built-in lead to be squeezed.SMA silks, SMA springs and lead work simultaneously, with this
Power consumption.Due to SMA silks and the good automatic recovery ability of SMA springs after vibrated so that damper restores to the original state, and reaches runback
The function of position, whole process realize highly energy-consuming and the runback bit function of damper well.
The present invention adjusts the distance between prestressed adjusted plate 3 and Zola's plate 15 to adjust by adjusting regulating bolt 14
The initial strain of SMA silks 5 and the quantity by lead built in change 16, the damping force of this damper is can adjust, makes this damping
Device application is more extensive.
The present invention is arranged on into large scale equipment or building during use to produce on the position of relative displacement, when structure is shaken
When dynamic, damper both sides rod member produces relative displacement, and portion of energy is damped device dissipation, with this oscillation damping and energy dissipating, reduces body junction
The dynamic respons of structure, after vibration stops, damper Self-resetting.
The present invention has the following advantages compared with prior art：Highly energy-consuming, Self-resetting, good endurance, thin tail sheep sensitivity, damping
Power is adjustable, simple structure is easy to assembly etc..Structural vibration reduction field will be widely used in.
