[0039] Civil engineering structures must meet safety requirements; failure to do so can lead to serious accidents, such as earthquake-induced building collapse. A key factor influencing civil structural safety is the performance of the vibration reduction system. Designing a vibration reduction system with simple structure and high vibration reduction energy efficiency has long been a goal in the field of engineering vibration reduction technology.

[0040] In order to solve the above technical problems, the cross-shaped inertia damping vibration reduction device provided in this application is not only simple in structure, but also can effectively eliminate vibration energy and improve vibration reduction efficiency.

[0041] The embodiment of the present application provides a cross-shaped inertia damping vibration reduction device, such as Figure 1 As shown, the vibration reduction device provided in this embodiment includes a vibration reduction component and two groups of support components.

[0042] The vibration damping assembly includes a diamond frame 5, a cross-shaped four-way connector 4, two hydraulic dampers 3 and two inertia containers 6. The diamond frame 5 can be extended and retracted along the diagonal direction of the diamond frame 5. The two corners of the diamond frame 5 located on one diagonal are respectively connected to one end of the two hydraulic dampers 3, and the two corners of the diamond frame 5 located on the other diagonal are respectively connected to one end of the two inertia containers 6. The four ends of the cross-shaped four-way connector 4 are respectively connected to the other ends of the two hydraulic dampers 3 and the other ends of the two inertia containers 6.

[0043] Each support assembly includes two bases 1 and a support structure 2. The support structure 2 includes a support plate 201, a connecting rod 202 fixed on one side of the support plate 201, and two support legs 203 fixed on the other side of the support plate 201. The two support legs 203 are respectively connected to the two bases 1, and the two support legs 203 are symmetrical along the straight line where the connecting rod 202 is located.

[0044] The support rods in the two support assemblies are connected to the two corners of the diamond frame 5 located on the same diagonal line. The base 1 in one group of support assemblies is fixed on the first structure 8, and the base 1 in the other group of support assemblies is fixed on the second structure 7. The side of the first structure 8 where the base 1 is fixed is parallel to the side of the second structure 7 where the base 1 is fixed.

[0045] The cross-shaped inertia damping vibration reduction device provided in this embodiment cleverly integrates the hydraulic damper 3 and the ball screw inertia container 6 through the cross-shaped four-way connector 4 and the diamond frame 5, significantly improving the vibration reduction device's ability to eliminate nonlinear vibrations. When subjected to external excitation, the vibration reduction device can effectively dissipate more vibration energy, significantly reducing the transmission of vibration to the building structure, thereby improving the energy consumption and vibration reduction efficiency; and can significantly reduce the actual mass and volume of the vibration reduction device, saving space, greatly simplifying construction operations, and improving the convenience of engineering construction, thus having extremely high application value.

[0046] like Figure 1 As shown, in the vibration reduction device provided in this embodiment, the diamond frame 5 is formed by four strip rods 501 hinged by a hinge shaft 502. Therefore, under the action of external force, two adjacent strip rods 501 of the diamond frame 5 can rotate along the hinge shaft 502 used for hinge connection, thereby realizing that the diamond frame 5 can be extended and retracted along the diagonal direction of the diamond frame 5.

[0047] Specifically, when the hydraulic damper 3 is subjected to pressure, the diamond frame 5 is driven to contract in the diagonal direction of the hydraulic damper 3 and to expand in the diagonal direction of the inertia container 6. As a result, part of the energy applied to the hydraulic damper 3 is transferred to and consumed by the inertia container 6, which can significantly improve the energy consumption and vibration reduction efficiency.

[0048] Similarly, when the hydraulic damper 3 is subjected to pressure, it drives the diamond frame 5 to expand in the diagonal direction of the hydraulic damper 3 and contract in the diagonal direction of the inertia container 6. As a result, part of the energy applied to the hydraulic damper 3 is transferred to and consumed by the inertia container 6, which can significantly improve the energy consumption and vibration reduction efficiency.

[0049] Similarly, when the inertia container 6 contracts or expands due to external force, part of the energy will be transferred to the hydraulic damper 3, which also plays a role in improving the energy consumption and vibration reduction efficiency.

[0050] like Figure 1 As shown, in the vibration damping device provided by this embodiment, the diagonal lines of the diamond-shaped frame 5 where the two hydraulic dampers 3 are located are parallel to the connecting rod 202, while the diagonal lines of the diamond-shaped frame 5 where the two ball screw-type inertia chambers 6 are located are perpendicular to the connecting rod 202. That is, in building applications, the two hydraulic dampers 3 are arranged longitudinally and the two inertia chambers 6 are arranged transversely. The hydraulic dampers 3 can not only dissipate some of the energy of the building's longitudinal vibrations but also transfer some of this energy to the inertia chambers 6, where it is dissipated by the inertia chambers 6. Similarly, the inertia chambers 6 can not only dissipate some of the energy of the building's transverse vibrations but also transfer some of this energy to the hydraulic dampers 3, where it is dissipated by the hydraulic dampers 3.

[0051] In the vibration reduction device provided in this embodiment, Figure 2 As shown, the hydraulic damper 3 includes a connecting earring 301, a cap 309, a cylinder 310, an oil seal 302, a piston rod 303, a working piston 305, a floating piston 306 and a first stud 308; the earring is fixed to the outer surface of the top of the cap 309, the piston rod 303 is fixed to the inner surface of the top of the cap, the cap is sleeved on the cylinder 310, the top of the cylinder 310 is sealed by the oil seal 302, the piston rod 303 passes through the oil seal 302 and extends into the hydraulic cylinder, and the piston rod 303 extends into A working piston 305 is provided at the end of the hydraulic cylinder. The working piston 305 divides the cylinder 304 into the hydraulic cylinder 304 and the air chamber 307. The hydraulic cylinder 304 is located between the oil seal 302 and the working piston 305. The air chamber 307 is located between the working piston 305 and the bottom of the cylinder 304. The floating piston 306 is located in the air chamber 307. The first stud 308 is screwed to the bottom of the cylinder 304; the earring is hinged to a corner of the diamond frame 5, and the first stud 308 is screwed to the cross-shaped four-way threaded tube 401.

[0052] Specifically, if Figure 2 As shown, when the connecting earring 301 is subjected to an external force, it drives the cap to move axially along the cylinder 304, thereby driving the piston rod 303 to move axially along the cylinder 304. In a specific embodiment, the piston rod 303 moves toward the first stud 308, and the working piston 305 also moves toward the first stud 308. This reduces the volume of the gas chamber 307, compressing the gas within the gas chamber 307 and causing the floating piston 306 to move toward the first stud 308. During this process, the gas compression consumes some energy, and the movement of the floating piston 306 also consumes some energy. The connecting earring 301 drives the diamond-shaped frame 5 to contract in the diagonal direction of the hydraulic damper 3 and to expand in the diagonal direction of the inertia container 6, transferring some energy to and consuming the inertia container 6.

[0053] In the vibration reduction device provided in this embodiment, Figure 3As shown, the inertia container 6 is a ball screw type inertia container 6. The ball screw type inertia container includes a connecting member 601, a first housing 602, a nut 603, a ball screw, a rolling bearing 605, a tightening nut 606, the nut 603, a second stud 607, a flywheel 608, and a second housing 609. The first housing 602 is fixedly sleeved on the nut 603, and the outer surface of the top of the first housing 602 is fixed to one end of the connecting member 601; the second housing 609 is fixedly sleeved on the rolling bearing 605, and the bottom of the second housing 609 A second stud 607 is screwed on; the external thread on the ball screw 604 is engaged with the internal thread on the nut 603 and one end of the ball screw 604 extends into the first shell, the external thread on the ball screw 604 is engaged with the rolling bearing 605 and the other end of the ball screw 604 is input into the second shell, and the flywheel 608 is fixed to the end of the ball screw 604 extending into the second shell by tightening the nut 606; one end of the connecting piece 601 is hinged to a corner of the diamond frame 5, and the second stud 607 is screwed on the cross-shaped four-way threaded tube 401.

[0054] Specifically, there are two tightening nuts 606 , the internal threads of the tightening nuts 606 are threadedly engaged with the external threads of the second stud 607 , and the two tightening nuts 606 are respectively located on both sides of the flywheel 608 to prevent the flywheel 608 from flying out during operation.

[0055] Specifically, an axis hole is opened at one end of the connecting member 601 for hinged connection with the diamond-shaped frame 5 , and the connecting member 601 can rotate along the hinge axis 502 at a corner connected to the diamond-shaped frame 5 .

[0056] Specifically, rolling bearing 605 ensures transmission between second housing 609 and ball screw 604. Ball screw 604, nut 603, and flywheel 608 work together to convert translational motion into rotational motion, achieving an inertial synergy. Furthermore, using a ball screw-type inertial element instead of a traditional mass element allows for a greater inertial force to be generated with a smaller physical mass, significantly reducing the mass and volume of the vibration reduction system, thereby saving space and greatly facilitating construction operations.

[0057] In the vibration reduction device provided in this embodiment, Figure 4 As shown, the cross-shaped four-way connector 6014 of the connector 601 includes four threaded tubes 401 and four oblique ribs 402. The four threaded tubes 401 are welded into a cross shape. The oblique ribs 402 are isosceles right-angled triangular plates welded to the outer walls of two adjacent threaded tubes 401. The two right-angled sides of the oblique ribs 402 are parallel to the axial directions of the two threaded rods to which the oblique ribs 402 are welded. The oblique ribs 402 help improve the stability of the cross-shaped four-way connector 6014 of the connector 601, ensuring the normal operation of the cross-shaped four-way connector 6014 of the connector 601.

[0058] The above is the structure of the cross-shaped inertia-capacitor damping vibration reduction device provided in this embodiment. The specific application scenario of the cross-shaped inertia-capacitor damping vibration reduction device provided in this embodiment is described below.
