(2) Under the working condition of normal use load, the three-dimensional shock insulation structure system has enough rigidity in the horizontal/vertical/swinging/twisting directions, so that the three-dimensional shock insulation structure can bear the normal use load of the structure without large deformation.
(3) When the dynamic load is small (subway vibration, wind vibration or earthquake is met more), the negative stiffness connecting device provides negative stiffness, and the three-dimensional shock insulation structural system provided by the invention has small stiffness in the horizontal/vertical/swinging/torsion directions, so that the novel three-dimensional shock insulation structure can isolate subway vibration and earthquake vibration in a wide frequency range, and is greatly superior to the traditional three-dimensional shock insulation/vibration structural system.
(4) When the dynamic load is large (rare earthquakes), the negative stiffness connecting device provides positive stiffness, the three-dimensional shock isolation structure system has large stiffness in the horizontal/vertical/swinging/torsion directions, and the anti-torsion/anti-swinging/anti-overturning capacity is correspondingly good, so that the overall displacement of the three-dimensional shock isolation structure under the rare earthquakes is reduced.

According to the three-dimensional shock insulation structure system, the rigidity and the damping of the horizontal shock insulation support are mainly determined by the mass and the rigidity of the upper structure and the frequency spectrum characteristic of the horizontal component of seismic motion, and the rigidity and the damping of the vertical shock insulation support are mainly determined by the mass and the rigidity of the upper structure and the frequency spectrum characteristic of the vertical component of the seismic motion. The pre-pressure, the compression rigidity and the damping of the negative rigidity connecting device are mainly determined by the frequency spectrum characteristics of horizontal and vertical subway vibration. The tensile stiffness and damping of the negative stiffness connection device are mainly determined by the spectral characteristics of the sway and torsion components of seismic motion.

The specific implementation mode is as follows:
in order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in fig. 1, 2 and 3, the three-dimensional seismic isolation structure system of the invention comprises a foundation 7, wherein a plurality of horizontal seismic isolation devices 4, vertical seismic isolation devices 3, a rigid floor 5 and an upper structure 8 are sequentially and fixedly stacked on the foundation 7; and a plurality of lateral baffles 6 are fixedly arranged on a foundation 7 for isolating the periphery of the horizontal shock isolation devices 4, and the lateral baffles 6 are connected with the rigid floor 5 through negative rigidity connecting devices 2.
The number and arrangement of the horizontal shock insulation devices 4 correspond to the number and arrangement of the columns arranged on the upper structure 8.
The number and arrangement mode of the vertical shock insulation devices 3 are the same as those of the horizontal shock insulation devices 4.
The negative stiffness connecting device 2 comprises a belleville spring 9, an outer sleeve 10, an inner guide rod 11, a middle baffle plate 12, a universal hinge 13 and an end flange 14, wherein the outer sleeve 10 is a cylinder body with one end connected with the end flange 14 provided with a central hole and the other end connected with the end flange 14 smaller than a small cylinder of the outer sleeve 10, the inner guide rod 11 is inserted into the outer sleeve 10, and the inner guide rod 11 is sequentially sleeved with the belleville spring 9 and the middle baffle plate 12; an inner guide rod 11 at one end of the outer sleeve 10 is connected with the lateral baffle 6 through the universal hinge 13, and a small cylinder at the other end is connected with the rigid floor 5 through the universal hinge 13.
A sealing ring 15 is further arranged between the end flange 14 and the inner guide rod 11. The outer sleeve 10 is also filled with silicone oil 16. The disk springs 9 are arranged in a pairwise mirror image manner.
The vertical shock insulation device 3 is a disc spring vertical shock insulation support; the horizontal shock isolation device 4 is a high-damping rubber support.
And the lateral baffle 6 and the rigid floor 5 are both made of concrete plates.
The upper structure 8 is a frame structure; the foundation 7 is a raft foundation.
The action principle is as follows:
the horizontal shock insulation device 4 in the three-dimensional shock insulation system 1 mainly isolates subway vibration and earthquake vibration in the horizontal direction, and the vertical shock insulation device 3 mainly isolates vertical subway vibration and earthquake vibration. Negative stiffness connection means 2 provide negative stiffness when in compression and positive stiffness when negative stiffness connection means 2 are in tension. When the three-dimensional shock insulation system 1 is in an initial state, the negative stiffness connecting device 2 is under the action of pre-pressing force and in a pressed state, so that negative stiffness is provided, the natural vibration frequency of the structure is reduced, and subway vibration and earthquake vibration in a wider frequency range can be isolated. When the three-dimensional shock insulation system 1 is subjected to a large load, the compressive pre-pressure of the negative stiffness connecting device 2 is released and is in a tension state, and positive stiffness is provided, so that the displacement of the structure under a limit load (strong shock) can be limited.
The negative stiffness connection means 2 has a good load bearing capacity in tension/compression and energy dissipation capacity. When the negative rate linkage 2 is in tension/compression limit, the compressed belleville springs 9 in the negative rate linkage 2 are in a flattened condition, preventing greater deformation. Under the action of an external load, when the negative stiffness connecting device deforms, the silicone oil flows in the outer sleeve to provide certain viscous damping energy consumption; in addition, mutual friction occurs between adjacent disk springs, and certain friction damping energy consumption is provided.
The three-dimensional shock insulation structure system has the three-dimensional six-direction rigidity self-adaption characteristic, namely the structure system can realize rigidity self-adaption to a certain degree in six directions: (1) under the working condition of normal use load, the three-dimensional shock insulation structure system has enough rigidity in the horizontal/vertical/swinging/twisting directions, so that the three-dimensional shock insulation structure can bear the normal use load of the structure without large deformation. (2) When the dynamic load is small (subway vibration, wind vibration or multiple earthquakes), the negative stiffness connecting device 2 provides negative stiffness, and the stiffness of the three-dimensional shock insulation structure system in the horizontal/vertical/swinging/torsion directions is small, so that the three-dimensional shock insulation structure can isolate subway vibration and earthquake vibration in a wide frequency range. (3) When the dynamic load is large (rare earthquakes), the negative stiffness connecting device 2 provides positive stiffness, the three-dimensional shock isolation structure system has large stiffness in the horizontal/vertical/swinging/twisting directions, and the anti-torsion/anti-swinging/anti-overturning capacity of the three-dimensional shock isolation structure system is correspondingly good, so that the overall displacement of the three-dimensional shock isolation structure under the rare earthquakes is reduced.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and all modifications, equivalents and improvements that are within the spirit and principle of the present invention are deemed to be within the scope of the present invention.
