Description
Technical field
The present invention relates to novel energy-consumption supporting damping device technologies, more particularly to the damping for becoming friction, runback bit function
Device control technology.
Background technique
104482093 A of Chinese patent CN discloses Self-resetting friction-changing damper, as shown in Figure 1, technology contents are such as
Under:
When Self-resetting friction-changing damper is in initial rest position, the elastomer 6 of 5 two sides of baffle is natural length,
I.e. pre compressed magnitude is zero.At this point, the both ends of elastomer are just contacted with baffle 5 and extruding voussoir 7 respectively, pressure on contact surface
It is zero, and squeezes and be also just in contact respectively between voussoir 7 and friction voussoir 8 and friction voussoir 8 and 1 inner wall of cylinder.Work as cunning
It when axis 2 is moved from initial position with respect to cylinder 1, for example moves downward, then right end consolidates seat by squeezing voussoir 7 and friction voussoir 8
Transmitting and squeeze the elastomer 6 on the right side of baffle, the elastomer 6 in the left side of baffle 5 is still natural length at this time.When 5 right side of baffle
Elastomer 6 compressed after, elastic force will squeeze the extruding voussoir 7 that contacts therewith, and squeeze voussoir 7 further through taper arc
Face jam-packed friction voussoir 8, so that the normal pressure between friction voussoir 8 and cylinder inboard wall increases with it.If rubbing voussoir 8 and cylinder
The coefficient of friction of inner wall is kept constant, then the size of the frictional force generated when opposite sliding and the decrement of elastomer occur for the two
It is directly proportional.When damper, which is placed in knot, sets structure interlayer, it can be according to the size adjust automatically friction of main structure displacement response
The numerical value of power.In addition to frictional force, the restoring force of Self-resetting friction-changing damper further includes elastic reaction, i.e., when slide-bar 2 deviates just
When beginning equilbrium position, the elastomer 6 of baffle side is because generating elastic force by compression, and the elastic force is further through squeezing voussoir 7, rub
The transmitting for wiping voussoir 8 and solid seat acts on slide-bar.The restoring force of Self-resetting friction-changing damper is equal to elastic reaction in load
It is identical as two power directions of the sum of frictional force, and in unloading for both two power of difference it is contrary.Elastic reaction numerically leads to
Often greater than frictional force, therefore when slide-bar deviates equilbrium position, it can return to initial position under elastic reaction effect, that is, hinder
Buddhist nun's device has runback bit function.In short, Self-resetting friction-changing damper can be adaptively according to main body when being run with working method
Structural displacement response adjusts frictional force size, has runback bit function.
The shortcomings that prior art:
1, although existing change friction re-centring damper has accomplished runback after the few energy consumption of small shake, the more energy consumptions of big shake and shake
The change friction control of position still has certain speed when structure is restored to equilbrium position under the effect of Self-resetting restoring force, right
Structure is unfavorable.
Although 2, existing friction-changing damper is realizing the semi- active control for shaking more less energy-consumings shakes greatly and consuming energy less,
It is relatively fewer in the smaller energy consumption of small shake bottom offset.
3, existing friction-changing damper friction plate directly rubs with outer tube, and long term can external pipe stiffness generation
Adverse effect.

Any position on wraping plate 9 is wiped, one group of butterfly spring 7 at both ends is all in pressured state；And it is glutinous in displacement maximum friction
Normal pressure maximum, that is, frictional force between elastic parts 5 and friction wraping plate 9 is maximum.
As shown in Figure 2,3, 4, the Self-resetting moving seesaw-type becomes the course of work of friction composite buffer are as follows:
1, working method when being pressurized: under the conditions of thin tail sheep, when the Self-resetting moving seesaw-type becomes friction composite buffer compression
Setting in motion, 1 left end arc-shaped concave of inner tube push the same Zuo Yun of slide bolt in 2 left end slot slideway 2 ' of outer tube to inner tube 1 to the left
It is dynamic, while the slide bolt that outer tube 2 pushes in 2 right end slot slideway 2 ' of outer tube slides to the right in interior tube seat hole slideway 1 ', by
It is hung on two slide bolts in the two ends of the hook of elastomer 4, so elastomer 4 is stretched at this time.Outer tube 2 moves right process
In by bolt 8 transfer power to friction viscoelasticity component 5 thick steel plate 51 on, and because friction wraping plate 9 in disk spring 7
Under the action of be that both ends are bent up, so friction viscoelasticity component 5 have when tendency toward sliding can extrusion friction wraping plate 9 have it is certain
Play sliding power.Since under small shake effect, thin tail sheep occurs for structure, what bolt 8 passed at this time is short of power so that the glutinous bullet that rubs
Property component 5 and friction wraping plate 9 occur it is opposite slide i.e. at this time not by rubbing come dissipation energy, but pass through the viscoelasticity group that rubs
Even if relative displacement occurs for the two panels steel disc of part 5, intermediate viscous-elastic material generation is shear-deformable, to utilize viscous-elastic material layer
It is shear-deformable come dissipation energy.And under the conditions of big displacement, friction viscoelasticity component 5 has broken through cunning power, with outer tube 2 after
It is continuous to move right, while inner tube 1 is moved to the left by fixed-hinged support component 6 with dynamic friction wraping plate 9, rub viscoelasticity group at this time
Part 5 starts extrusion friction wraping plate 9, rotates clockwise friction wraping plate 9 around fixed-hinged support component 6, i.e. friction 9 right end of wraping plate
Sinking, 7 compression deformation of disk spring in 1 the right groove of inner tube increases, and because the left end of friction wraping plate 9 tilts,
Disk spring compression deformation in 1 groove of inner tube reduces, and friction 9 left end uplift portion bending degree of wraping plate becomes smaller, and is computed
Show that the frictional force to be rubbed between viscoelasticity component 5 and the wraping plate 9 that rubs at this time constantly increases.Make the viscoelasticity that rubs when continuing load
Frictional force has reached maximum when component 5 reaches at displacement amplitude, and the stroke of slide bolt 3 has also reached maximum, inner and outer pipes at this time
On slot slideway start limiting displacement at this time and continue to develop.Two panels during this section of climbing on friction viscoelasticity component 5
Viscous-elastic material layer shear action constantly increases the shear-deformable increase energy consumption of i.e. viscous-elastic material layer and also increases between steel plate centering, together
When constantly increase due to frictional force, friction energy-dissipating becomes main energy consumption mode, and the elongation of this process elastomer 4 also constantly increases
I.e. elastic restoring force is added constantly to increase, elongation is 1 ' length of slot slideway in inner tube 1.Elasticity when unloading in elastomer 4 is extensive
Under multiple power effect, left end slide bolt 3 starts to push inner tube 1 to right end movement, until left end slide bolt 3 slides into outer tube 2
Spacing slotted eye slideway 2 ' right end, in the process rub viscoelasticity component 5 and friction wraping plate 9 between frictional force gradually become smaller
Frictional force is zero when initial position, while when the restoring force of elastomer 4 effect flowering structure is restored near initial position
The speed that structure has becomes larger, and rigidity of structure conversion more acutely leads to the increase of structure interlayer acceleration, but due to rubbing
The presence for wiping viscoelasticity component 5 is equivalent to a small-sized viscoelastic damper i.e. velocity-dependent damper, can effectively reduce
Speed big problem when above structure is restored to initial position, so play buffer structure rigidity conversion, reduce structure interlayer add
The effect of speed.
2, working method when tension: under the conditions of thin tail sheep, when the Self-resetting moving seesaw-type becomes friction composite buffer tension
Inner tube 1 starts to move to the right, and inner tube 1 drives the slide bolt 3 in inner and outer pipes slot slideway in 2 right end slot slideway of outer tube
It is slided to the right in 2 ', while the slide bolt 3 that outer tube 2 hauls in 2 left end slot slideway 2 ' of outer tube moves downward, due to elastomer
4 two ends of the hook is hung on two slide bolts, so elastomer 4 is stretched at this time.Outer tube 2 passes through spiral shell during being moved to the left
Bolt 8 transfers power on the thick steel plate 51 of friction viscoelasticity component 5, and the viscoelasticity component 5 that rubs at this time has the tendency that climbing, meeting
Extrusion friction wraping plate 9 is to generate frictional force, since under small shake effect, thin tail sheep occurs for structure, and bolt 8 passes at this time
It is short of power with the stiction for breaking through friction viscoelasticity component 5 between the wraping plate 9 that rubs, so not consumed at this time by rubbing
Energy is dissipated, but opposite rubbing is occurred by the two panels steel disc for the viscoelasticity component 5 that rubs, intermediate viscous-elastic material is cut
The effect of cutting, to utilize the shear-deformable come dissipation energy of viscous-elastic material layer 52.And under the conditions of big displacement, rub glutinous bullet
Property component 5 broken through sliding power, as outer tube 2 continues to be moved to the left, at the same inner tube 1 by fixed-hinged support component 6 with dynamic friction
Wraping plate 9 moves right, and the viscoelasticity component 5 that rubs at this time starts extrusion friction wraping plate 9, and the wraping plate 9 that makes to rub is around fixed-hinged support
Component 6 rotates counterclockwise, i.e. friction 9 left end of wraping plate sinks, and the disk spring compression deformation in 1 left side groove of inner tube increases,
Again because the right end of friction wraping plate 9 tilts, 7 compression deformation of disk spring in 1 the right groove of inner tube reduces, and friction is stuck up
9 left end uplift portion bending degree of plate becomes smaller.It is computed and obtains rubbing between viscoelasticity component 5 and the wraping plate 9 that rubs of rubbing at this time
Power is wiped constantly to increase.When continuing load and reaching friction viscoelasticity component 5 at displacement amplitude, frictional force has reached maximum, at this time
The stroke of slide bolt 3 has also reached maximum, and the slot slideway on inner and outer pipes starts limiting displacement at this time and continues to develop.In this section
52 shear action of viscous-elastic material layer constantly increases i.e. glutinous between two panels steel plate centering during climbing on friction viscoelasticity component 5
The shear-deformable increase energy consumption of elastomeric layer also increases, simultaneously because frictional force constantly increases, friction energy-dissipating becomes main energy consumption
Mode, the elongation of this process elastomer 4 are also continuously increased i.e. elastic restoring force and constantly increase, and increased length is inner tube 1
Upper slot slideway length.When unloading under the elastic restoring force effect of elastomer 4, left end slide bolt 3 start to push inner tube 1 to
Left end is mobile, until left end slide bolt 3 slides into the left end of the spacing slotted eye slideway of 2 right end of outer tube, rubs in the process
Frictional force is zero when frictional force is become progressively smaller until initial position between viscoelasticity component 5 and friction wraping plate 9, while in elastomer
The speed that structure has when 4 restoring force effect flowering structure is restored near initial position becomes larger, and rigidity of structure conversion is more
Acutely lead to the increase of structure interlayer acceleration, but since the presence of friction viscoelasticity component 5 is equivalent to a small-sized glutinous bullet
Property damper, that is, velocity-dependent damper, can effectively reduce speed big problem when above structure is restored to initial position,
And then plays the role of the conversion of buffer structure rigidity, reduces interlayer acceleration.
