Description
The invention relates to the acceptor of energy that is used for large scale structure, this acceptor of energy is to alleviate the extraneous motion that produces to the influence of this class formation with Come.The application is with United States Patent (USP) 4,499, and the invention in 694 will be referred to as the source invention.
The alternating shear energy absorbing device utilizes the alternate plasticity distortion Come that exceeds elastic limit of some material to absorb kinetic energy.This kind absorber very typically is inserted between the support component and basic components of building, or between two part structural supports, like this, the part of the kinetic energy in the absorbing material can be converted into heat, thereby reduce the motion that extraneous strength transmission is given building, as earthquake or high wind.Authorize Robinson's United States Patent (USP) 4,117,637 are published on October 3rd, 1, and exercise question is " an alternating shear acceptor of energy ", its disclosure at this as a reference, this patent with picture specification several geometries of this basic circulation shear energy absorbing device.This base apparatus contains two wetting fluid parts, is typically plate, and each parts all is connected with an independent structure member.When this device is used for builing industry, makes one of them link invest a pile foundation, and another link is invested on the object an of support column, beam and so on.But being installed between two links is the solid matter of alternate plasticity distortion, is typically lead, the plumbous absorption energy that can rise.Some structure of this device also comprises an added resilience attenuator structure, this structure is around the energy absorption material and an elasticity longitudinal bracing is arranged between two links, normally by a material that resembles the sandwich shape, it comprises the interchangeable layer and a rigid material (as: steel, aluminium or allied substances) of an elastomeric material (as: rubber).
In application, when extraneous strength causes two links to do relative lateral movement, the energy absorption solid matter surmount it elastic limit and alternation make some energy change into heat energy and can under this material is in deformed state, store dump energy, the latter is equivalent to a kind of driving force, and its trend is material is replied its original mechanical performance.As a result, the energy that is delivered to or transmitted this structure changes into heat, and can infringement not arranged to building.Thereby and the structure that is bound up of this absorber than the structure (it will be damaged by violent earthquake and be difficult to and repair or replace) of the ductile performance energy dispersive of those dependency structure parts and use rubber absorbers structure (this structure image spring is worked like that and only disperseed the energy of very a spot of outside Come of transmission) safety many.
Find that in many application the above-mentioned type acceptor of energy function is fine, and in some applications, the too early degeneration of energy absorption material appear at the little swing of amplitude in sight after.
This is owing to lack restriction to absorbing material, this material can with the direction of forcing deformation on arbitrarily elongation, thereby, reduce its effect as an acceptor of energy.Even those its plumbous nuclear of energy absorption by one its have in the example that the resiliency supported attenuator of sandwich structure centers on, the degree of restriction also is according to being disinclined to the size of longitudinal loading, the hardness of elastomeric material and the thickness of elastomeric material individual course.Particularly, if at this moment longitudinal loading less than 0.4 times of the rated load of brace table, and is that the shear strain of half inch elastic layer is 0.5 to the elastomeric material hardness number between the 50-55 and thickness, plumbous core capabilities just may be degenerated.
The purpose of this invention is to provide an improved alternating shear acceptor of energy, in this device, in fact the degeneration of performance has reduced, and in other words, provides a useful selection to the public at least.
The present invention comprises an improved alternating shear acceptor of energy, and it has a longer application life on known energy absorber basis, and it has the advantage of the energy absorption of original device.
In the most wide scope, the present invention comprises an alternating shear acceptor of energy in order to absorb owing to the energy that motion produced between two parts.Acceptor of energy comprises and is suitable for first and second linkages that are connected with first and second parts, as support building support column, be connected the plasticity alternation deformable energy absorbing device between first and second connectors, and one be positioned at around the energy absorbing device, i.e. the limiter in zone between first and second linkages.This limiter has a flexible metope and limit energy absorbing device when moving to produce between two parts, and allows energy absorbing device to produce deformation in desirable mode simultaneously.This flexible metope has elasticity to absorb vertical component.Simultaneously, still limit energy absorbing device.Preferably among the embodiment, the spiral basically flat part of energy absorbing device outer surface and a flexible metope that is provided by independent winding layers of being centered around is provided limiter one of the present invention.It is to be made it to separate with the bed of material that adjoins by elastomeric material that this winding layers has a part at least.
Preferably among the embodiment, limiter comprises a series of flat part that are centered around the energy absorbing device outer surface basically at another, and it is to be made it to separate with adjacent components by elastomeric material that this flat part has a part at least.
Limiter preferably by be assemblied between first and second linkages a resiliency supported Come around.This resiliency supported preferably can comprise an elastomeric material, as the alternately bed of material and sturdy material of rubber, as steel, aluminium or glass fiber reinforced plastic.In geometry preferably, energy absorbing device comprises a cylindrical bore between the end face of first and second linkages.Limiter be one spiral around the flat wound pipe.Resiliency supported comprises the rectangle or the tetragonal bed of material of rubber and steel, and it has a cylindrical aperture by the center, to receive limiter and this core.
Making of the present invention is performed such: the assembling resiliency supported, be preferably in guiding anchor clamps and assist insertion limiter down, have the axle of the diameter that equates with the required interior diameter of limiter and in limiter, place energy absorption nuclear as one, its mode for pressure with pack into the hollow interior of limiter or core is cast into limiter inside of core.
In one embodiment, absorber has end plate, is fitted together with modes such as hot glue, connections.On an end plate that is closely linked with cylinder energy absorption nuclear, a hole is arranged, be shaped on screw thread.The end cap that is shaped on screw thread is screwed into this hole to compress this core.

The embodiment of Fig. 1 to Fig. 6 can obtain so that it comprises characteristic property of the present invention to improve by adding elastomeric material near at least some limiting parts between the bed of material.
Please see Figure now, Fig. 1 shows the phantom drawing of a desirable embodiment of source invention.Just as shown in the drawing.This energy absorbing device comprises that a central energy absorbs core 2, and its type shape is a cylinder, 3, one resiliency supported 4 of flexible limiter and top and bottom junction plate 7 and 8 around core 2.
As shown in Figure 2, resiliency supported attenuator 4 has the structure of a sandwich shape, the interchangeable layer that it comprises elastomeric material 5 preferably adopts such as the natural and such elastomeric material of synthetic rubber, and rigid slab 6 is preferably made by steel, aluminium, glass fiber reinforced plastic, fiber or other rigid material.The effect of resiliency supported 4 is equivalent to a bearing pad that is intended to shift by this device longitudinal loading.Support 4 typically is installed in the bottom of longitudinal bracing beam, is connected or depends on base plate 8. Individual course 5 and 6 typically is combined with each other to form a single structure.The most normally the way with hot glue forms.
Energy absorption nuclear 2 is preferably made by the cylindrical high-quality lead of being showed.The wording of high-quality lead is intended to illustrate that purity reaches 99.9%.In many application, plumbous purity is low slightly, and approximately bottom line is 98%.Other suitable material is the material in No. the 4th, 117,637, the United States Patent (USP) spoken of in the above and other material with identical alternate plasticity deformation characteristics.
Device illustrated in figures 1 and 2 is pressed routine mode and is made as.Square shown at first being combined into by individual component, or some other suitable geometry Come makes and supports 4, and the center annular aperture is rearranged cylindrical space, generally is positioned at 4 the center of supporting.Then, limiter 3 is inserted into these apertures, when inserting preferably by means of the help of a cylinder axle.Afterwards, energy absorption nuclear 2 is pressed into the inside of limiting element, and after this, mode is arranged shown in top and the bottom plate basis.We find that best result obtains like this: when using the plumbous making of high-quality energy absorbing element 2, at first cast the cylinder absorber, this absorber is pressed in the limiter 3 again.The external diameter of cylinder absorber elements 2 should be slightly more a little bit smaller than the internal diameter of element 3, absorbs the surface, inside that device 2 can successfully slip into limiting element 3 like this.In addition, cylinder absorber elements 2 should be more slightly longer than the axial length of the device of finishing.In casting during this acceptor of energy element 2, the interior diameter of model is should be basically the same with the diameter in the cylinder aperture of this resiliency supported 4.
If necessary, acceptor of energy element 2 can be cast in the cylinder of resiliency supported 3.As adopt this possible alternative to make this device, when the casting molten core, should be taken into account plumbous thermal expansivity, do not cause with the atrophy that guarantees core in cooling subsequently between the inner surface of the superficies of core parts 2 and limiting element 3 too big gap is arranged, in order to obtain optimum efficiency, should notice guaranteeing that core parts 2 are completely restricted on all surfaces, promptly be surrounded on cylinder abutment wall surface and top and the lower surface.
In operation, this device be installed in structure a such as bridge or building support member and the basis such as between the ground.Under a structure is in the vibration of earthquake, high wind or other natural phenomena band Come and when causing shearing force to forward on the energy absorbing device, the form distortion that this device promptly is under these shearing forces and shows according to Fig. 3.Just as shown in this figure, core parts 2 change along with shearing force from its original right cylinder shape, and limiting element 3 has also experienced same motion.Because the rectangular cross-sectional shape of limiting element 3, the bed of material winding that adjoins becomes the shape of displacement shown in Figure 3 from vertical linear slide of their former Come as shown in Figure 2.Yet, have the elasticity bed of material 5 Come around enough surfaces and its that vertical support is provided between the bed of material that adjoins, preventing limiting element avalanche or distortion, total core parts 2 can keep its cylindrical shape like this, although cylinder itself is to vertical distortion.To give this wall surface flexible for the internal layer of the independent winding layers of limiting element 3 surface and the sliding arrangement of adjoining the bed of material in addition, makes core parts 2 can carry out enough distortion Come energy dispersive, keeps the integrality of core parts simultaneously again.As shown above, most of energy is disperseed by the core parts 2 inner heat that produce, and simultaneously, energy remaining is stored among element 2 and the resiliency supported 4.This energy of being stored is used for the material of this core is sent back to the machine performance of its former Come.In addition, the release that is stored in the energy part in the resiliency supported 4 will be tending towards core parts 2 are returned to the geometry states of described its former Come of Fig. 2.
The actual tests that the energy absorbing device that the indication of basis source invention is made carries out shows that the useful life of the energy absorbing device of this modified form is longer than the similar device that an original technology of basis is built greatly, but lacks limiting element 3.
The result of the research project of carrying out in Zelanian University of Auckland specifically, describes in following publication to some extent:

For summing up these achievements, the internal layer of 20 15 * 12 * 4 inches filling plumb supporting surfaces and 5 half inchs has been carried out the widely dynamic test of longitudinal loading and shear-bow amplitude. 25 longitudinal loadings combining and each in the shear-bow have experienced the displacement measurement of five alternations. Dispersed energy be zone from the load offset hysteresis loop with significant level glue intensity, elastic hardness and elasticity after hardness measure together. To the multiple plumbous state that is not unrestricted be studied and with its result with contrast being subjected to the result that plumbous cylinder that above-described mode limited tests. Bel spy (in 198 2) is described specific test result, and these results generally show: when plumbous cylinder is restricted, the energy that disperses in each circulation will double above.
In many application, the friction between the composition surface of the friction between the composition surface of the lower surface of upper board 7 and the top bed of material 5 and the upper face of lower panel 8 and the elasticity bed of material 5 that adjoins is enough to provide shearing action above-described and that Fig. 3 partly shows. Having In a little the application, preferably plate 7 and 8 and be inserted in the middle of resiliency supported 4 between extra connection is provided. Provide the skill of this extra connection to comprise plate 7 and plate 8 are connected on the end surface of this resiliency supported 4, can adopt the ways such as hot glue, stickup. In other was used, desirable way was to provide extra connection between plate 7, plate 8 and resiliency supported 4. Fig. 4 has showed first alternate embodiment of origin invention, and a reliable connection power namely is provided between plate 7, plate 8 and resiliency supported 4. Just as shown in this figure, the lower surface of upper board 7 fills a connecting ring 11, the rectangle of its geometry and resiliency supported 4(such as figure one) periphery identical. The shape of ring 11 and angle are so that the topmost of resiliency supported 4 can enter ring 11 when plate 7 is put into resiliency supported 4. The upper face of bottom plate 8 is equipped with a similar connecting ring 12, and the angle of this ring is basically identical with ring 11 with shape. In use, the lateral displacement between plate 7 and the plate 8 is transferred to resiliency supported 4, and this transmission is not only backup plate 7, plate 8 and supports frictional force between 4, and by ring 11, ring 12 with support mechanical force between 4. Ring 11 and ring 12 can be contained on plate 7 and the plate 8 ways such as available welding, brazing filler metal, stickup in any suitable manner.
Fig. 5 and Fig. 6 have showed an alternate embodiment of source invention, namely provide one to connect reliably between plate 7, plate 8 and resiliency supported 4. Just as shown in this figure, upper board 7 is equipped with the sagging pin plug 13 of some, arranges according to predetermined mode, and four plugs 13 are arranged in annular, and its gap is 90 degree, is surrounded on the center of core original paper 2. The aperture 14 of respective numbers places on the rigid plate 6 of the elasticity bed of material 5 of topmost and topmost equally in advance. The aperture 14 extensible parts of passing whole topmost rigid plate 6 or only passing this plate. The arrangement in plug 13 and aperture 14 makes plug 13 be pressed into aperture 14 when top plate 7 is lowered into resiliency supported 4. Lower panel 8 is equipped with the pin plug 15 that a similar fashion is arranged, and corresponding aperture 16 is housed on the foot elasticity bed of material 5 and the foot rigid plate 6.
Although desirable embodiment is described to preferably comprise lower panel 7 and plate 8, During some was used, these plates can be put into relevant structure member, and perhaps, the function of plate 7 and plate 8 can be provided by the determined surperficial Come of relevant structure member. For example lower panel 8 can comprise the upper face of the concrete foundation of a power plant, and upper board 7 can be used as the bottom of the containment of power plant. The people who knows well this technology also can associate other thing.
Though foregoing has disclosed the desirable embodiment of source invention all sidedly, it is also conceivable that and carry out improvement miscellaneous and adopt preparation method miscellaneous, and unlikely true spirit and the scope that deviates from the source invention.For example,, still can adopt other geometric ways, as rectangle, trapezoidal, oval or the like though the right cylinder geometry has been described to preferential embodiment.Furtherly, though resiliency supported 4 is declared as rectangle, other geometry also can be used for this composite component, comprises circle.In addition, although limiting element is described to contain the cylinder of flat screw thread, also can adopt other shape, this depends on the geometry of core parts 2 itself.For example adopted the rectangle core parts, limiting element will have a similar rectangle so.In addition, if necessary, limiting element can comprise the individual component longitudinally enumerated together (circular flat ring, the flat frame of rectangle, or the like).
Fig. 1 comprises element 3 in the embodiment that Fig. 6 describes, below will be called close circle spiral.Each circle among this embodiment all contacts with adjoining of oneself.Its weakness is that this supporting surface becomes from vertical hard, may produce serious harm to spiral with the way dress system that is press-fitted the time.In order to prevent this shortcoming, in Fig. 7 and Fig. 8, shown a kind of alternative structure, in the middle of each of these structures, plumbous core 2 is limited element and centers on.But this element has vertical compressibilty of certain amount.
In the described embodiment of Fig. 7, spiral winding 3 is centered on as urea or silicon rubber by elastomeric material 17.In a desirable embodiment, this is to adopt the skill Come that makes the hydraulic pressure suction pipe to make by a flexible pipe manufacturer.Adding elastomeric material 17 between the independent winding 3 of spiral promptly provides a loosely wound spiral structure, and this structure does not have the weakness of the close circle spiral of foregoing description.
In another embodiment that Fig. 8 describes, supporting surface 1 contains the plumbous core 2 of cylinder and end plate 7 and 8.Except the end of plumbous core 2, whole element is centered on by elastomeric material 5.In this embodiment, around plumbous core, elastomeric material 5 is for each circle of spiral 3 and provide the bed of material between pad or the rigid slab 6 separately across pad or rigid slab 6 for 3 of loosely wound spirals.Spiral 3 is divided into independent circle in the present embodiment.
In Fig. 7 and Fig. 8,, enumerate together with what elastomeric material separated that ring may be utilized as continuous helical 3 or the spiral part 3 that separates.
In all embodiment, have only some element 3 to be separated from each other, so that certain longitudinal elasticity is provided in flexible wall.
We see that the elastomeric material that adds between the bed of material of spiral or the ring-shaped material layer can not influence the ability of the plumbous core of limiter limits, has so just kept the described advantage of Fig. 1 to Fig. 6 in its action.
In Fig. 9, an embodiment comprises the alternating layer of 7, one lower panel 8 of a upper board, elastomeric material 5 and rigid material 6.Plate 7 and plate 8 are passed in aperture 9, and they can be connected on structure or the basis.Pass plate 7 with the corresponding hole of the cross section of core 2.Be shaped on screw thread in this hole and set up the suitable screw of diameter 19, to assist vertical restriction of core 2.Must be noted that screw 19 is tightly screwed on, so that plate 7 is unlikely from 5 separation of the elasticity bed of material.Place the weight of the structure on the plate 7 when this device is positioned under the building, will be guaranteed to this point.
Equally, other geometry being discussed when speaking of Fig. 1 to Fig. 6 also is suitable for being arranged among Fig. 7,8 and 9.Therefore, foregoing description should not be considered to limit scope of the present invention, and the present invention is defined by additional claim.
