Description

Technical Field

[0001] This invention belongs to the field of damper technology, specifically relating to a modular torsional solid extrusion damper. Background Technology

[0002] In recent years, seismic isolation and energy dissipation technologies have developed rapidly and have been widely applied in practical engineering fields, especially in civil buildings such as schools and hospitals, and have withstood numerous earthquake tests. With the rapid development of seismic isolation and energy dissipation technologies, new concepts, technologies, and products are constantly emerging. Seismic isolation technologies such as laminated rubber bearings, friction pendulum bearings, and rubber sliding bearings, as well as various energy dissipation damping devices, are now more prevalent.

[0003] While oil dampers offer relatively good vibration reduction, their reliability, durability, and maintenance during service remain concerns. Eddy current damping technology provides an effective solution for energy dissipation, vibration reduction, and vibration control, and its application in critical infrastructure such as important buildings and bridges is increasing. However, its cost is currently still relatively high compared to other types of dampers. In contrast, non-metallic materials such as high-damping rubber and metallic materials such as lead have been widely used in lead-core rubber bearings and dampers due to their good plastic deformation capacity and fatigue resistance. Therefore, there is an urgent need to develop a damper that can reduce structural vibration response and improve structural energy dissipation capacity. Summary of the Invention

[0004] The purpose of this invention is to overcome the problem of how to develop dampers that can reduce the vibration response of a structure and increase its energy dissipation capacity, and proposes a modular torsional solid extrusion damper.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: In a first aspect, the present invention provides a modular torsional solid compression damper, comprising a first outer steel plate, a second outer steel plate, a first connecting plate, a second connecting plate, an inner steel plate assembly, and an anti-loosening fastening assembly arranged coaxially. The first outer steel plate and the second outer steel plate are axially separated at both ends along the central axis of the damper. The inner steel plate assembly is stacked between the first outer steel plate and the second outer steel plate. The first outer steel plate, the inner steel plate assembly, and the second outer steel plate are clamped and positioned by an axially penetrating anti-loosening fastening assembly. The first connecting plate is fixedly connected to both the first outer steel plate and the second outer steel plate. In the two adjacent steel plates, one steel plate has protrusions evenly distributed around the central axis of the damper on its opposite end face, and the other steel plate has grooves evenly distributed around the central axis of the damper on its opposite end face. The protrusions are embedded in the grooves, and the outer wall of the protrusions and the inner wall of the grooves enclose a closed filling cavity. The filling cavity is filled with an energy-dissipating medium. Each inner steel plate group has an axially penetrating material passage hole, which connects the filling cavities on both sides of the steel plate. The material passage hole is filled with an energy-dissipating medium. The inner steel plate assembly includes at least one second inner steel plate, and a first inner steel plate is provided between two adjacent second inner steel plates. The number of second inner steel plates is consistent with the number of energy dissipation module groups of the damper. The first outer steel plate, the second outer steel plate, and the inner steel plate assembly are all provided with bolt mounting holes for the installation of anti-loosening fastening components. The bolt mounting holes of the second inner steel plate are arc-shaped long slots that extend circumferentially with the central axis of the damper as the center. The first connecting plate is fixedly connected to the first inner steel plate, and the second connecting plate is fixedly connected to the second inner steel plate.

[0006] Furthermore, both the protrusions and grooves are fan-shaped structures, with the number of protrusions matching the number of grooves. Each protrusion and groove is evenly distributed circumferentially around the central axis of the damper.

[0007] Furthermore, one axial end face of the first inner steel plate is provided with a protrusion, and the other axial end face is provided with a groove. The bolt mounting holes of the first inner steel plate are circular through holes.

[0008] Furthermore, one axial end face of the second inner steel plate is provided with a protrusion, and the other axial end face is provided with a groove. The number of arc-shaped long slots in the second inner steel plate is the same as the number of bolt mounting holes in the first outer steel plate.

[0009] Furthermore, the first outer steel plate has a protrusion on its axial end face facing the inner steel plate assembly, and the second outer steel plate has a groove on its axial end face facing the inner steel plate assembly.

[0010] Furthermore, the material passage hole is set within the radial coverage range of the groove, the material passage hole is set within the design torsional displacement range of the damper, and the material passage hole is located within the axial projection range of the filling cavity; The material passage hole can be any one or more combinations of circular holes and strip holes, and the number of material passage holes is at least one. Each material passage hole is evenly distributed around the central axis of the damper.

[0011] Furthermore, the energy-consuming medium is either lead or high-damping rubber.

[0012] Furthermore, the anti-loosening fastening assembly includes an anti-loosening high-strength bolt, a lock nut, and a flat washer. The anti-loosening high-strength bolt axially penetrates all bolt mounting holes, and the lock nut and flat washer are respectively located on the outer end faces of the first outer steel plate and the second outer steel plate.

[0013] Secondly, the present invention provides a diagonal brace node damping structure, including a modular torsional solid compression damper, and further including a first diagonal brace and a second diagonal brace. The first connecting plate of the modular torsional solid compression damper is fixedly connected to the first diagonal brace, and the second connecting plate of the modular torsional solid compression damper is fixedly connected to the second diagonal brace. The modular torsional solid compression damper serves as a torsional connection node between the first diagonal brace and the second diagonal brace.

[0014] Thirdly, the present invention provides an interlayer damping structure, including a modular torsional solid compression damper, a lower diagonal brace assembly, a top main structure, and a pin connector. The first connecting plate of the modular torsional solid compression damper is fixedly connected to the lower diagonal brace assembly. The second inner steel plate of the modular torsional solid compression damper has a slotted hole, and the pin connector passes through the slotted hole. The second inner steel plate is hinged to the top main structure through the pin connector.

[0015] Compared with the prior art, the present invention has the following beneficial technical effects: This invention proposes a modular torsional solid extrusion damper that utilizes high-damping rubber and other non-metallic materials, as well as lead and other metallic materials, to dissipate energy through extrusion. It can be used for structural energy dissipation, vibration reduction, and vibration control. The modular design allows for flexible performance adjustment and convenient application. Through a stackable structure of inner steel plates, the number of energy-dissipating modules is matched with the number of second inner steel plates, and a first inner steel plate is placed between adjacent second inner steel plates. The number of modules can be flexibly adjusted according to engineering vibration reduction requirements, achieving precise customization of the damper's mechanical performance. The standardized steel plate structure facilitates batch processing, on-site assembly, and subsequent maintenance, significantly reducing production and construction costs. A torsional limiting structure ensures stable and controllable force. Through the interlocking of protrusions and grooves in adjacent steel plates, the damper is strictly limited to torsional deformation only around its central axis, avoiding in-plane shear, offset, and other non-target deformations, ensuring a clear force path, stable force transmission, and consistency and controllability of the energy dissipation process. It is highly energy-efficient and has strong operational reliability. The material passage holes in the inner steel plate connect the two filling cavities. During torsional deformation, the energy-consuming medium is squeezed and reciprocates through the passage holes to dissipate vibration energy, resulting in good hysteresis performance. The closed filling cavities prevent the energy-consuming medium from overflowing, and the anti-loosening fastening components counteract the expansion force of the medium. The arc-shaped long slot hole adapts to torsional displacement without jamming, greatly improving the fatigue performance and long-term working stability of the damper.

[0016] Furthermore, the dual-connecting plate split force transmission structure can be directly adapted to various engineering scenarios such as diagonal bracing nodes and inter-story vibration reduction, with a wide range of applications and strong engineering promotion value.

[0042] Example 1 The modular torsional solid extrusion damper disclosed in this embodiment includes a first outer steel plate, a second outer steel plate, a first connecting plate, a second connecting plate, an inner steel plate assembly, an anti-loosening fastening component, and an energy-dissipating medium, all coaxially arranged. The first and second outer steel plates are axially positioned at both ends of the damper along its central axis. The inner steel plate assembly is coaxially stacked between the first and second outer steel plates. The first outer steel plate, the inner steel plate assembly, and the second outer steel plate are clamped and positioned axially by an axially penetrating anti-loosening fastening component. The first connecting plate is fixed to the end face of the first outer steel plate facing away from the inner steel plate assembly, and the second connecting plate is fixed to the end face of the second outer steel plate facing away from the inner steel plate assembly. The first connecting plate is also fixedly connected to the first inner steel plate in the inner steel plate assembly, and the second connecting plate is also fixedly connected to the second inner steel plate in the inner steel plate assembly, serving to connect the damper to both ends of the external main structure and transmit torsional deformation. In two axially adjacent steel plates, one steel plate has protrusions evenly distributed around the central axis of the damper on its opposite end face, and the other steel plate has grooves evenly distributed around the central axis of the damper on its opposite end face. The protrusions are fitted into the grooves one by one. The outer wall of the protrusion and the inner wall of the groove form a closed filling cavity, which is filled with an energy-dissipating medium.

[0043] In this embodiment, both the protrusions and grooves are fan-shaped structures. The number of protrusions is the same as the number of grooves, and each protrusion and groove is evenly distributed equidistantly around the central axis of the damper. The axial end face of the first outer steel plate facing the inner steel plate group has protrusions, and multiple circular bolt mounting holes evenly distributed around the central axis are provided on the first outer steel plate for inserting anti-loosening fastening components. The axial end face of the second outer steel plate facing the inner steel plate group has grooves, and multiple circular bolt mounting holes evenly distributed around the central axis are provided on the second outer steel plate. The bolt mounting holes of the second outer steel plate are coaxially corresponding to the bolt mounting holes of the first outer steel plate. The inner steel plate group includes at least one second inner steel plate, and a first inner steel plate is disposed between two adjacent second inner steel plates. The number of second inner steel plates is the same as the number of energy dissipation module groups of the damper. One axial end face of the first inner steel plate has a protrusion, and the other axial end face has a groove. The first inner steel plate has circular bolt mounting holes evenly distributed around its central axis, and these bolt mounting holes correspond coaxially with those of the first outer steel plate. One axial end face of the second inner steel plate has a protrusion, and the other axial end face has a groove. The second inner steel plate also has bolt mounting holes evenly distributed around its central axis. These bolt mounting holes are arc-shaped long slots, extending circumferentially with the central axis of the damper as the center. The number of these arc-shaped long slots is the same as the number of bolt mounting holes on the first outer steel plate, and the circumferential extension length of the arc-shaped long slots matches the design torsional deformation stroke of the damper. Both the first and second inner steel plates in the inner steel plate assembly have axially penetrating material passage holes. The material passage holes connect the filling cavities on both sides of the inner steel plate and are filled with energy-dissipating media. The material passage holes are located within the radial coverage area of ​​the groove. Within the design torsional displacement range of the damper, the entire opening area of ​​the material passage holes is always located within the axial projection range of the filling cavity. In this embodiment, the material passage holes are any one or more combinations of circular holes and strip holes. The number of material passage holes is at least one, and each material passage hole is evenly distributed circumferentially around the central axis of the damper.

[0044] In this embodiment, the energy-consuming medium is either lead or high-damping rubber, and the energy-consuming medium in the filling cavity and the energy-consuming medium in the material passage hole are made of the same material. The anti-loosening fastening assembly includes an anti-loosening high-strength bolt, a lock nut, and a flat washer; the anti-loosening high-strength bolt passes axially through the bolt mounting holes on all the first inner steel plates, second inner steel plates, and second outer steel plates in the first outer steel plate and inner steel plate group in a direction parallel to the central axis of the damper; the flat washer is respectively placed on the outer end face of the first outer steel plate away from the inner steel plate group and the outer end face of the second outer steel plate away from the inner steel plate group; the lock nut is threadedly engaged with the screw end of the anti-loosening high-strength bolt to clamp and fix all steel plates axially.

[0045] Optionally, the damper is equipped with a set of energy dissipation modules, including a second inner steel plate, which is stacked axially between the first outer steel plate and the second outer steel plate.

[0046] Optionally, the damper is equipped with two sets of energy dissipation modules. The inner steel plate group includes two second inner steel plates and one first inner steel plate. The first inner steel plate is disposed between the two second inner steel plates, and the two second inner steel plates are respectively disposed close to the first outer steel plate and the second outer steel plate.

[0047] Optionally, the damper is equipped with three or more energy dissipation modules, and the inner steel plate group is equipped with a second inner steel plate with the same number of energy dissipation module groups. A first inner steel plate is set between each adjacent second inner steel plate.

[0048] The following description, in conjunction with the accompanying drawings, further explains and illustrates a modular torsional solid compression damper of the present invention: The damper's adjacent steel plates are fitted with grooves and protrusions to ensure that the damper can only deform around its center. At the initial position, a protrusion on one side of the steel plate embeds into a groove in the adjacent steel plate. The protrusion fills a portion of the groove, with the remaining space filled by energy-dissipating solids. When the damper deforms, the energy-dissipating solids are forced through a material passage in the inner steel plate to the other side. Two adjacent sets of energy-dissipating solids and their adjacent steel plates form an energy-dissipating module. One or more energy-dissipating modules can be configured according to the damper's performance requirements.

[0049] The novel form of the damper in this invention allows for modular assembly based on its performance. Space for placing energy-dissipating solids 5 can be formed between every two adjacent steel plates; every three adjacent steel plates and their internal energy-dissipating solids 5 and 6 can form a set of energy-dissipating modules. A set of energy-dissipating modules refers to modules where energy-dissipating solids 5 are located on both sides of the inner steel plate, and the material passage holes 6 of the inner steel plate are filled with energy-dissipating solids. When relative torsional deformation occurs between the steel plates in the module, the energy-dissipating solids 5 on one side of the inner steel plate can be squeezed into the other side through the material passage holes 6.

[0050] A modular torsional solid extrusion damper includes two connecting plates 8, a first outer steel plate 1, a second outer steel plate 2, multiple first inner steel plates 3 and second inner steel plates 4, and energy-dissipating solids 5 and material passage holes 6 arranged on both sides of the inner steel plates, with the material passage holes filled with energy-dissipating solids. The first inner steel plates 3 and second inner steel plates 4 are modularly arranged in groups between the first outer steel plates 1 and second outer steel plates 2, and the outer steel plates and inner steel plates are clamped together by anti-loosening fastening components 7.

[0051] When the damper undergoes torsional deformation, the space between adjacent steel plates increases on one side and decreases on the other. The space between adjacent steel plates is filled with energy-dissipating solids. As the size of the space changes with the torsional deformation of the damper, the volume of the energy-dissipating solids on one side of the inner steel plate decreases under pressure and enters the larger space on the other side through the material passage in the inner steel plate within the range of energy-dissipating solids.

[0052] When the damper undergoes torsional deformation, the internal energy-dissipating solid is compressed, which generates a lateral expansion force on the inner and outer steel plates. The damper resists the expansion force generated by the internal energy-dissipating solid during torsional deformation through the anti-loosening fastening component 7 that passes through the outer and inner steel plates, so that the inner and outer steel plates fit tightly together.

[0053] The adjacent steel plates are torsionally deformed only around the center of the damper by setting a groove on one side of the steel plate and a protrusion on the other side of the steel plate that fits tightly with the groove.

[0054] The steel plate configuration allows multiple sets of first and second inner steel plates to be stacked to form a modular assembly. The energy-dissipating solids filling the spaces between adjacent steel plates are also modularly assembled. This allows the damper to be configured with the number of inner steel plates and energy-dissipating solids according to performance requirements, and the damper's performance parameters can be flexibly adjusted through modular assembly.

[0055] Space for placing energy-dissipating solids can be formed between every two adjacent steel plates; every three adjacent steel plates and the energy-dissipating solids between them can form an energy-dissipating module. An energy-dissipating module means that there are energy-dissipating solids on both sides of the inner steel plate within the module. When relative torsional deformation occurs between the steel plates in the module, the energy-dissipating solid material on one side of the inner steel plate can be squeezed into the other side through the material passage holes in the inner steel plate. The material passage holes in the inner steel plate are always within the area where the energy-dissipating solids of the adjacent steel plates are located within the design displacement of the damper.

[0056] The following description uses a damper comprising two sets of energy-dissipating modules as an example to illustrate the modular torsional solid compression damper of the present invention: The outer contour of the first outer steel plate 1 is composed of arcs and polygons, such as Figure 1 As shown. A central circular hole is formed, and fan-shaped protrusions are evenly distributed around the center on one side. A circular hole is provided near one side of the fan-shaped protrusions for the bolt to pass through.

[0057] The outer contour of the second outer steel plate 2 is composed of arcs and polygons, such as Figure 2 As shown. A central circular hole is formed, and a fan-shaped groove is evenly distributed around the center on one side. A circular hole is provided near one side of the fan-shaped groove for the bolt to pass through.

[0058] The outer contour of the first inner steel plate 3 is composed of arcs and polygons, such as Figure 3As shown. A central circular hole is formed, and fan-shaped protrusions are evenly distributed around the center on one side, while fan-shaped grooves are evenly distributed around the center on the other side. A circular hole is provided near one side of the fan-shaped protrusions for bolts to pass through, and a material passage hole 6 is provided on the other side for energy-consuming solids to be compressed and pass through to enter from one side to the other when the damper deforms. There can be one or more material passage holes 6, and their shape can be circular, strip-shaped, etc., depending on the performance requirements of the damper. Within the design deformation range of the damper, the material passage hole is always within the range of energy-consuming solids in the adjacent steel plate grooves.

[0059] The outer contour of the second inner steel plate 4 is composed of arcs and polygons, such as Figure 4 As shown. A central circular hole is formed, and fan-shaped protrusions are evenly distributed around the center on one side, while fan-shaped grooves are evenly distributed around the center on the other side. An arc-shaped slot is provided near one side of the fan-shaped protrusions for bolts to pass through, and a material passage hole is provided on the other side for energy-consuming solids to pass through and enter from one side to the other when the damper deforms. There can be one or more material passage holes, and their shape can be circular, strip-shaped, etc., determined according to the damper's performance requirements. Within the damper's designed deformation range, this material passage hole is always within the range of energy-consuming solids in the adjacent steel plate grooves.

[0060] When the outer and inner steel plates of the damper are assembled in their initial positions for use, the fan-shaped protrusions of the outer and inner steel plates are embedded into the fan-shaped grooves of the adjacent steel plates. That is, a portion of the space in the fan-shaped grooves is filled by the fan-shaped protrusions, while the remaining space in the grooves is filled by energy-dissipating solids, such as... Figure 7 and Figure 8 As shown.

[0061] The inner steel plate has circumferential through-holes 6, which allow the energy-dissipating solid material 5 to be compressed and transferred from one side of the inner steel plate to the other when the damper deforms. The through-holes 6 are filled with energy-dissipating solid material. An example of filling the through-holes 6 with energy-dissipating solid material when they are circular is shown below. Figure 6 As shown.

[0062] When the dampers of two sets of energy dissipation modules are in the initial design position, such as Figure 7 As shown, the cross-sectional view of the energy-consuming solid 5 and the material passage hole 6 of the inner steel plate is as follows. Figure 8 As shown, the energy-dissipating solid volumes on both sides of the inner steel plate are the same in the initial position. When the damper undergoes a clockwise twist and deforms to its maximum position, as... Figure 9 As shown, the volume of energy-consuming solid on one side of the inner steel plate decreases due to compression, and it enters the other side of the inner steel plate through the material passage, causing the volume of energy-consuming solid on the other side to increase. Figure 10 As shown. When the damper undergoes counterclockwise torsion and deforms to its maximum position, as... Figure 11 As shown, the deformation trend of the energy-consuming solid 5 is opposite to that of clockwise torsion, as... Figure 12As shown. When the damper is applied to structural vibration control, the energy-dissipating solids 5 on both sides of the inner steel plate undergo volume reciprocating changes as the damper deforms and is squeezed. During this process, the structural vibration energy is dissipated, thereby realizing the energy dissipation, vibration reduction and vibration control functions of the damper of this invention.

[0063] A side view of the modular application of the damper of this invention is shown below. Figure 13 , Figure 14 , Figure 15 As shown, there are one, two, and three sets of energy dissipation modules, respectively. In practical applications, multiple sets of energy dissipation modules can be assembled according to the performance requirements of the damper. The form, size, number, and arrangement of the material passage holes 6 set in the energy dissipation solid 5 of the inner steel plate will affect the hysteretic energy dissipation characteristics of the damper. These parameters can be changed according to actual needs to adjust the mechanical performance of the damper.

[0064] like Figure 18 and 19 This invention discloses a modular torsional solid extrusion damper, a vibration reduction device that utilizes a solid with good deformability at room temperature to dissipate energy during extrusion deformation. It can be applied to buildings to reduce the vibration response of structures or equipment. The damper comprises two connecting plates 8, two outer steel plates, multiple sets of inner steel plates, an energy-dissipating solid 5, and anti-loosening fastening components 7 (anti-loosening high-strength bolts). The connecting plates 8 connect the damper to the main structure or base requiring vibration reduction; an outer steel plate is provided on each side of the damper, and multiple sets of inner steel plates are provided in the middle; the outer and inner steel plates are clamped together by the anti-loosening fasteners 7; the inner and outer steel plates are respectively connected to the connecting plates 8. The energy-dissipating solid in this invention can be made of non-metallic materials such as high-damping rubber or metallic materials such as lead, filling the gaps between adjacent steel plates. The novel construction allows the connecting plates 8 to rotate only around the center of the damper. When the connecting plates 8 at both ends of the damper undergo relative torsional deformation, the space on one side between the inner steel plate and the adjacent steel plate increases while the space on the other side decreases. This causes the lead block on the side with the reduced space to be compressed and enter the side with the increased space through the pre-set opening in the inner steel plate. During this process, the damper dissipates energy through the compression deformation of the energy-dissipating solid, thereby suppressing structural vibration. The special structural form of the inner steel plate allows for modular assembly, with multiple energy-dissipating modules set according to the performance requirements of the damper. This invention utilizes the deformability and fatigue resistance of the energy-dissipating solid, and through a novel structural form, it possesses excellent energy dissipation performance, flexible modular assembly, and broad application prospects.

[0065] Example 2 A diagonal brace node damping structure includes the modular torsional solid compression damper of Embodiment 1, and also includes a first diagonal brace and a second diagonal brace. The first connecting plate of the modular torsional solid compression damper is fixedly connected to the first diagonal brace, and the second connecting plate of the modular torsional solid compression damper is fixedly connected to the second diagonal brace. The modular torsional solid compression damper serves as a torsional connection node between the first diagonal brace and the second diagonal brace.

[0066] Specifically, the modular torsional solid compression damper of this invention can be used as a connection node between two diagonal braces in a structure, such as... Figure 16 As shown, when the two diagonal braces undergo torsional deformation, the adjacent steel plates inside the damper also undergo torsional deformation, thereby playing an energy dissipation role and suppressing structural deformation.

[0067] Example 3 An interlayer damping structure includes a modular torsional solid compression damper as described in Embodiment 1, and further includes a lower diagonal brace assembly, a top main structure, and a pin connector. The first connecting plate of the modular torsional solid compression damper is fixedly connected to the lower diagonal brace assembly. The second inner steel plate of the modular torsional solid compression damper has a slotted hole, and the pin connector passes through the slotted hole. The second inner steel plate is hinged to the top main structure through the pin connector.

[0068] Specifically, the modular torsional solid compression damper of this invention can utilize interlayer deformation of the structure for energy dissipation and vibration reduction, such as... Figure 17 As shown, the lower part of the damper is connected to two diagonal braces, and the upper part is connected to the top main structure via a pin joint.
