Description
[technical field]
The present invention relates to a kind of energy absorbing material and its energy absorbing device of use that for example when earthquake takes place, is used to reduce the vibrational energy that is passed to building and civil construction etc.
[background technique]
Up to now, because high ductibility or low recrystallization temperature, above-mentioned vibrational energy absorbent material all uses plumbous always.Yet, because the enhancing of environmental consciousness recently, also considering that lead-free brazing etc. uses plumbous possibility with control.
As the substitute of lead, considered to have and the plumbous equal high ductibility and the tin (Sn) of low recrystallization temperature, because tin is harmless, therefore also be used for food industry and device and home-use tableware etc., it is general to have many uses.
Yet there is allotropic transformation point (with reference to following non-patent literature 1) in tin about 18 ℃, be generally megathermal β-Sn, yet, if be under the severe cold condition, may change the α-Sn of low form into.Because α-Sn is hard and crisp, if allotropic transformation takes place, mechanical property can change, and has energy absorption ability problem of unstable.In addition, usually knownly can expand changing the α phase time mutually into from β, disintegration becomes the sand shape.Therefore, there is the problem that is difficult at low temperatures tin is used as energy absorbing material.
For suppressing above-mentioned allotropic transformation, add bismuth, cadmium, gold, silver, antimony in the oriented tin and make the method for alloy, yet affix reduces the purity of tin, the problem that ductility reduces or recrystallization temperature rises occurred.
On the other hand, up to now, following patent documentation 1,2 discloses for example as the energy absorbing device that reduces the vibrational energy that is passed to building and civil construction when earthquake takes place.Figure 15 has shown an example of this device, the energy absorbing device A structure of this example is as follows: form lamination body 3 at elastomers 2 such as hard plates such as steel plate 1 and rubber mutual laminated multi-layer on above-below direction, central part at this lamination body 3, be arranged on the hollow space 3a that connects on the above-below direction, in this hollow space 3a, hold being provided with the energy absorber 4 that constitutes by elastoplastic materials such as lead that absorbs vibrational energies such as earthquake.In addition, in last Figure 15, for avoiding intricate, hard plate 1 is omitted with the hatching (oblique line of expression section) of elastomer 2 and energy absorber 4.
As shown in figure 15, in two ends up and down of above-mentioned lamination body 3 and energy absorber 4, be installed together by substrate 5 and mounting plate 6 respectively, this mounting plate 6 is to be installed in structure on building and the civil construction by not shown bolt etc.Specifically, for example for as shown in figure 16 buildings such as building, between substructure body C such as the upper structure B of this building etc. and its ground, or for as shown in figure 17 civil construction such as bridge, between substructure body C such as upper structure B such as bridge girder and bridge pier, be provided with one or more above-mentioned energy absorbing device A respectively, by inserting bolt in the above-mentioned mounting hole (not shown) that forms in the lower installation board 6 on this each energy absorbing device A etc., it is installed on said structure body B, the C.
Aforesaidly be arranged on energy absorbing device A between up-down structure body B, the C when stably supporting building etc., can also when earthquake takes place, be out of shape in the horizontal direction and seismic energy is reduced, have existing what is called simultaneously and exempt to shake isolator and exempt to shake two kinds of functions of vibration damper.The result compares with the situation that above-mentioned isolator and vibration damper are set respectively, has following advantage: the space is set can reducing, simultaneously, has also improved operability.
In addition, in above-mentioned patent documentation 2, disclose when making above-mentioned energy absorbing device, applied identical or greater than the hydrostatic pressing of this stress with this shear yield stress to the energy absorber that constitutes by elastoplastic material.This is processing energy absorber and lamination body is integrated and that must carry out, like this, energy absorber and lamination body is deformed into one, promptly can absorb the vibrational energy of earthquake etc.That is to say, if energy absorber is because earthquake etc. deforms, and energy absorber is flexible in the longitudinal direction, by with the direction of length direction quadrature on produce diameter the plastic deformation of dwindling, increasing absorb vibrational energy.
Yet, near the outer peripheral portion of energy absorber, because pressing, the frictional force on lamination rubber hollow space surface or energy absorber be absorbed in lamination body, we can say in order to form stationary state, actual conditions are, if energy absorber, will cause the angle of collapsing, bight in the corner of energy absorber because earthquake etc. and produce distortion repeatedly, near the end of energy absorber, cause the expansion of diameter, near the middle body of energy absorber, cause the contraction of diameter.This is considered near the end owing to energy absorber, and energy absorber state of changing with the central part vicinity is different to be caused, mainly thinks owing to be subjected to that the difference of the outer peripheral portion of energy absorber of the sunken influence of frictional force or energy absorber pressure and energy absorber internal modification produces.
The result, since near two ends of energy absorber with middle body near, the deformation direction of energy absorber is different with amount of deformation, and except the expansion of the collapse angle and the diameter in above-mentioned bight was shunk, the poorest situation was to cause the problem that produces crack etc. in energy absorber.In addition,, there is the energy not only can't stably absorb regulation if energy absorber is in above-mentioned state, and the also problem of variation of durability.
On the other hand, for obtaining having the energy absorbing device of more high attenuation power, must further increase the diameter of the energy absorber in the lamination body, perhaps increase the number that is provided with of energy absorbing device, if the diameter of energization absorber, then when making, must use bigger power energy absorber to be inserted the hollow space of lamination body with press machine etc., not only must use huge equipment, and because the frictional force of the hollow space inner face of energy absorber and lamination body and pressure fall into increase, the problems referred to above can be more serious.In addition, blindly increase energy absorbing device number is set the time, bigger space and the more construction cost of being provided with must be arranged when building, this is always unpractical.

Embodiment
Below, energy absorbing material of the present invention and its energy absorbing device of use are carried out specific description.
Usually, in the energy absorbing device that absorbs vibrations such as earthquake because buildings etc. are because of the location variation of earthquake etc., usually preferably with respect to exempt from blanket roughly can servo-actuated 20% or more than, preferred 40% or more than.At that rate, energy absorbing material is also wished naturally to have and can be guaranteed 20% or above, preferred 40% or the performance of above specific elongation.
Therefore, in the present invention, relate to a kind of energy absorbing material that is used to absorb vibrational energies such as earthquake, be made up of the following elastoplastic material that forms: based on purity is 99 weight % or above tin, to wherein adding any a kind or 2 kinds be selected from bismuth, cadmium, gold, silver, the antimony or above metal as adding metal, and make alloy, with respect to this elastoplastic material, the ratio of above-mentioned interpolation metal is 40 weight % or following, and the specific elongation of above-mentioned elastoplastic material be 20% or more than.
The purity that is to use that Fig. 1 shows is the main body of the tin of 99 weight % as elastoplastic material, ratio of mixture (weight %) when wherein mixing as the bismuth that adds metal and making alloy, and use the elastoplastic material test film that forms by this alloy, carry out in the tension test maximum tension specific elongation (%) when rupturing according to JIS Z 2201.Wherein, use the above-mentioned alloy test film made by size shape shown in Figure 2 test film, under 20 ℃ temperature, carry out with the speed of 500mm/min as above-mentioned tension test.The unit of size is mm among Fig. 2.In addition, consider the deviation of sample, N=3 tests by sample number.Test described later also is like this.In addition, the combined amount of above-mentioned bismuth suitably changes in the scope of 0.2 weight %～50 weight %.In addition, as a reference, also in the situation that only contains the tin that purity is 99 weight % (combined amount of bismuth is 0 weight %) shown in the same figure.
Found that, as elastoplastic material, blending bismuth and making under the situation of alloy in the tin that to purity is 99 weight %, if the combined amount of bismuth progressively increases, then maximum specific elongation can reduce.Yet it reduces ratio and sharply reduces when combined amount is 0～10 weight % left and right sides, and after this when combined amount is the 40 weight % left and right sides, specific elongation is reduced to 20% from 40% more lentamente, if combined amount surpasses 40 weight %, specific elongation sharply reduces again.
In addition, by above-mentioned Fig. 1 as can be seen, if the adding quantity of bismuth (combined amount) is 10 weight % or following, then specific elongation be 40% or more than, if the adding quantity of bismuth is 1 weight % or following, then obtain 60% or above specific elongation.
Fig. 3 has shown the tension test of carrying out in above-mentioned Fig. 1 tensile strength (to the tensile strength of fracture) is with respect to only being the ratio (tensile strength than) of the tin of the 99 weight % tensile strength when forming test film same as described above and carrying out tension test by purity.Found that if increase the combined amount of metal, tensile strength increases.Yet, under its increment rate reduces when combined amount reaches boundary about 40 weight %.That is to say, be to improve tensile strength efficient good mixing scope below being controlled at combined amount about 40 weight %.
In addition, The above results shows the combined amount by metal, can change tensile strength arbitrarily.That is to say, for example when needs obtain to have the lamination rubber laminate of about 3 Pirellis, use the elastoplastic material of the interpolation metal formation of in the elastoplastic material main body, adding about 10 weight % to get final product as energy absorber (core body).In sum, as seen combined amount is controlled at about 40 weight % below, the equilibrium of specific elongation, tensile strength falls in the best scope.
Then, be that the test of the tin of 99.9 weight % describes to using purity.Use the sample shown in the following table 1, confirm influence and the effect of affix mechanical property and recrystallization temperature.As affix, use bismuth as typical example.In addition, for comparing, be that the lead of 99.99 weight % also carries out same test to purity.And to use purity be the tin of 99.99 weight %～99 weight %, confirms influence and effect that purity produces mechanical property.

Fig. 6 has shown the tensile strength in the affix dependence test.That is, will show that promptly purity is to add the tin alloy that the bismuth of established amount forms as affix in the tin of 99.9 weight %, carries out the result's of tension test figure according to the main points identical with above-mentioned Fig. 4 to above-mentioned table 1 sample tin alloy (1).In this test, along with the increase of affix amount, tensile strength increases thereupon.Under adding quantity arbitrarily, all can confirm to have the tensile strength higher than lead.
Fig. 7 has shown the specific elongation in the affix dependence test.That is, will show that the bismuth to adding established amount in the above-mentioned table 1 sample tin alloy (1) forms tin alloy, the figure of the specific elongation (%) when stretching according to the main points identical with above-mentioned Fig. 5 as affix.In this test, increase along with the affix amount, specific elongation reduces thereupon, the approximate curve that obtains by this test, can find that affix is in the 5.0 weight % time, identical with the specific elongation of 99.99 weight % lead, affix is in the 4.0 weight % time, and is also bigger than the specific elongation of 99.99 weight % lead.
Next, for confirming near the normal temperature whether recrystallization is arranged, subtend purity is to add the sample that the bismuth of 5.0 weight % obtains in the tin of 99.9 weight %, the section tissue before and after stretching with microscopic examination.Wherein, under the situation that does not produce recrystallization, crystalline particle is because tension test forms the shape that axially stretches, and if cause that recrystallization, crystalline particle diminish, the shape of formation sub-circular.In addition, by observation, can confirm under 20 ℃, how many adding quantitys can cause recrystallization until to section tissue before and after stretching.
