Description

Background
The three-dimensional vibration isolation device can play a vibration isolation role in the horizontal and vertical directions. The students at home and abroad strive to obtain certain research results for many years, and three-dimensional shock insulation devices such as disc springs-single friction pendulum three-dimensional shock insulation devices, inclined three-dimensional shock insulation supports and the like are developed.
A disc spring-single friction pendulum three-dimensional shock insulation device will be described with reference to fig. 1. Fig. 1 is a schematic structural view of a disc spring-single friction pendulum three-dimensional shock insulation device. As shown in figure 1, the device consists of two parts, wherein a disc spring vertical shock insulation unit is arranged above the device, the disc spring vertical shock insulation unit consists of a plurality of rows of disc spring groups with central symmetry, and a single friction pendulum horizontal shock insulation unit is connected in series below the disc spring vertical shock insulation unit. The single friction pendulum unit is used for realizing horizontal shock isolation, and the disc spring unit is used for realizing vertical shock isolation. However, the lower vertical rigidity of the three-dimensional shock insulation device enables the pre-compression deformation of the three-dimensional shock insulation device under the dead weight load of the upper structure to be larger, and the rigidity of the structure required under the static load cannot be well met.
Next, a description will be given of a three-dimensional shock-insulating mount of an oblique sliding type with reference to fig. 2. Fig. 2 is a schematic structural view of a three-dimensional shock-insulating support of an oblique sliding type. As shown in fig. 2, the support is mainly composed of a lead rubber support with the upper part for horizontal shock insulation, a sliding connecting piece in the middle, a sliding friction block and a lead rubber support with the lower part for vertical shock insulation. The vertical deformation and the vibration isolation effect are realized by obliquely placing the lead rubber support, converting the vertical deformation of the structure into the compression shear deformation of the lower support and the friction sliding of the friction block, and the vertical vibration isolation effect of the three-dimensional vibration isolation support is determined by the shear rigidity and the compression rigidity of the lower oblique lead rubber support. However, after the lead rubber support is obliquely placed, the creep problem of the rubber support is more remarkable under the state of pressure shear deformation, so that the lower oblique lead rubber support of the device is not deformed in coordination under the action of an earthquake, and the working performance of the device cannot be effectively exerted.

Referring to fig. 3, fig. 3 is a schematic structural diagram of an embodiment of a novel three-dimensional vibration isolation device according to the present invention. As shown in fig. 3, the device comprises an upper connecting steel plate 1, a connecting plate 2, a lower connecting steel plate 3, a molecular spring assembly and a lead rubber assembly. The upper connecting steel plate 1 and the lower connecting steel plate 3 are respectively connected with the upper buttress 5 and the lower buttress 6 through bolts.
In some embodiments, the molecular spring assembly is disposed between the upper connection steel plate 1 and the connection plate 2 for vertical shock insulation and vertical damping. Specifically, the molecular spring assembly includes an annular groove 21 connected to the above-described connection plate 2. The bottom of the upper connecting steel plate 1 is provided with an annular pressing plate 11 adapted to the annular groove 21. The annular groove 21 is filled with a viscous liquid and a molecular sieve material. Further, a molecular spring upper sealing plate 23 is further arranged on the annular groove 21, so that leakage of viscous liquid is avoided. In the assembled state, the annular pressing plate 11 is inserted into the annular groove 21 and engaged with the molecular spring upper seal plate 23.
When the load of the viscous liquid exceeds a threshold value, the viscous liquid intrudes into micropores of the molecular sieve material. During the pressure relief phase, mucus can spill out of the microwells. The energy can be stored and released in the process of leading a large amount of viscous liquid into and out of the micropores. In addition, the viscous liquid also has a damping effect.
Therefore, in the standing state, the viscous liquid is compressed, and high vertical bearing rigidity can be provided to bear the load of the upper buttress.
Under the action of vertical earthquake, the load of viscous liquid in the molecular spring component exceeds a critical value, and the viscous liquid invades into micropores of the molecular sieve material. The viscous liquid invades the micropores of the molecular sieve material, so that the molecular spring assembly not only generates damping, but also enters a low-rigidity stage, the self-vibration period of the structure can be effectively prolonged, and the functions of vibration isolation and vertical damping are realized.
When the intensity of vertical earthquake makes the viscous liquid be full of the micropore of molecular sieve, the micropore is saturated, at this moment, receives outside load after, and the viscous liquid is compressed, and molecular spring assembly appears high rigidity this moment, and the vertical displacement of this molecular spring assembly can be restricted to the high bearing capacity that this kind of high rigidity brought, consequently can play spacing protection mechanism to this shock insulation device.
Therefore, the molecular spring assembly has three sections of rigidity of high, low and high, and the rigidity which can be changed meets the requirements of high bearing capacity and low vibration isolation rigidity of the three-dimensional vibration isolation support.
It should be noted that, the above critical value may be determined by the following formula:
P＝-2σ L cosθ/r；
wherein P is a critical value for critical pressure characterization;
σ L is the surface tension of the liquid;
θ is the solid-liquid contact angle;
r is the hydrophobic pore radius.
During the process of penetrating the mucus into the micropores of the molecular sieve material until saturation, the molecular spring assembly enters a low stiffness state, and the stiffness is related to the penetration amount of the mucus into the micropores.
In addition, after determining the viscosity and molecular sieve material, the critical values for the critical pressure characterization described above may be determined. Therefore, the bearing pressure of the viscous liquid can be determined as the critical value of the invasion of the viscous liquid into micropores of the molecular sieve material by changing the area of the annular groove 21, so that the requirement of rigidity of the molecular spring assembly under the action of static load can be met.
The viscous liquid may be silicone oil, hydraulic oil, or suspension. The molecular sieve material may be zeolite or silica gel particles. The determination of the above-mentioned viscous liquid and molecular sieve materials can be carried out by a person skilled in the art based on common general knowledge or prior art.
Further, the novel three-dimensional vibration isolation device also comprises a pulling-resistant mechanism, wherein the pulling-resistant mechanism comprises a connecting ring 12, a connecting ring baffle 13 and an annular groove baffle 22. The upper end (direction in fig. 3) of the connection ring 12 is fixedly connected to the upper connection steel plate 1. The ring baffle 13 is engaged with an inner wall of a lower end of the ring 12, and the ring groove baffle 22 is fitted over an outer wall of the ring groove 21. In a rest state, the lower end surface of the annular groove baffle 22 is engaged with the upper end surface of the connecting ring baffle 13. In this way, the connecting ring baffle 13 is clamped below the annular groove baffle 22, so that the annular groove 21 and the annular pressing plate 11 can be prevented from being separated, and the reliability of the shock insulation device is improved. The connecting ring 12 and the connecting ring baffle 13 may be integrally manufactured. The annular groove 21 may also be integrally formed with the annular groove shutter 22. In order to provide a compression space for the annular pressure plate 11 to compress the molecular spring assembly, the upper connecting steel plate 1 is disposed with a gap from the upper end surface of the annular groove 21.
The lead rubber component is arranged between the connecting plate 2 and the lower connecting steel plate 3 for horizontal shock insulation. Specifically, the lead rubber assembly includes a lead 43, a plurality of rubber layers, and a steel plate 42 disposed in the vertical direction. The rubber layers are alternately stacked with the steel plates. The steel plate 42 and the rubber layer are vulcanized to be connected and are fitted over the lead 43. The upper and lower ends of the lead core rubber assembly are also provided with an upper seal plate 41 and a lower seal plate 44. In a rest state, the upper seal plate 41 is joined to the connection plate 2, and the lower seal plate 44 is joined to the lower connection steel plate 3. The lead rubber assembly further includes a rubber protection layer 45 for protecting the steel plate from rust, and the rubber protection layer 45 is wrapped around the rubber layer, the upper sealing plate 41, the lower sealing plate 44, and the steel plate 42.
The lead core can absorb energy by plastic deformation when the rubber layer is in shear deformation, and automatically restores to the original position through dynamic restoration and recrystallization processes and the shearing tension action of the rubber layer after earthquake, thereby playing a role in limiting horizontal displacement.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present invention, and not for limiting the same; although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the invention.
