Description

Technical Field

[0001] This invention relates to the field of structural vibration reduction and isolation technology, and in particular to a torsional energy dissipation support device. Background Technology

[0002] In seismic-resistant steel structures, buckling-restrained braces (BRBs) are the most widely used components that provide both lateral support and energy dissipation. These components typically use a low-yield-strength ductile metal core, connected by restraints (usually mortar-filled steel tubes) and unbonded materials or gaps between them. The ductile metal core is connected to the main structure, providing lateral support during seismic loads and dissipating energy through plastic deformation. The restraints primarily prevent buckling instability of the metal core under compression, ensuring full-section yielding and enhancing its energy dissipation capacity. The unbonded material eliminates axial force transmission between the metal core and the restraints. These components are relatively complex, especially when filling the steel tubes with mortar, making construction quality difficult to guarantee. Furthermore, the aforementioned measures to prevent core buckling result in high steel consumption and cost for BRBs.

[0003] To address the aforementioned issues, existing technologies employ a seismic-resistant component design, using a mandrel as the core component connected to the main structure via support rods at both ends, as an alternative to the BRB component. However, this design, in addition to torsional yielding, frequently exhibits bending yielding along the load direction during vibration damping and energy dissipation. This means the mandrel is prone to deformation in directions other than torsional energy dissipation (such as bending deformation), affecting the component's energy dissipation performance and significantly reducing its fatigue life. Furthermore, this design lacks symmetrical force recovery characteristics during energy dissipation and vibration reduction; the mandrel experiences different torsional angles under the same tension / compression stroke. Consequently, the vibration energy consumed by the mandrel differs during tension / compression energy dissipation, increasing the risk of component failure and reducing its safety and reliability. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a torsional energy dissipation support device that improves the buckling strength and fatigue life of torsional tubes and has a compact structure.

[0005] To solve the above-mentioned technical problems, the technical solution proposed by this invention is as follows:

[0006] A torsional energy dissipation support device includes a torsion tube energy dissipation assembly and two sets of connecting rod assemblies. The torsion tube energy dissipation assembly is disposed between the two sets of connecting rod assemblies. The torsion tube energy dissipation assembly includes two torsion tubes connected to corresponding connecting rod assemblies, a bending moment resisting component that bears the shear force when the torsion tubes are torsionally twisted, and a fixing component that forms a torsion fixing point for the torsion tubes. The two torsion tubes are fixedly connected to each other through the fixing component. The bending moment resisting component is sleeved on the outside of the torsion tubes, and the torsion tubes are rotatable relative to the bending moment resisting component.

[0007] As a further improvement to the above technical solution:

[0008] The central axes of the two sets of connecting rod assemblies coincide, and the torsion tube is located on the outer side of the corresponding connecting rod assembly; both sets of connecting rod assemblies are connected to the torsion tube on the corresponding side through a force transmission assembly, and the two sets of force transmission assemblies are arranged symmetrically along the length direction of the connecting rod assembly.

[0009] The force transmission component includes a force transmission shaft and a force transmission plate. The connecting rod assembly, the force transmission shaft, and the force transmission plate are hinged in sequence. The force transmission plate is fixedly connected to the torsion tube. The force transmission plate is perpendicular to the fixed component.

[0010] The fixing component includes an end fixing plate, which is fixedly connected to the torsion tube; the bending moment resisting component includes a bending moment resisting plate, which is sleeved on the outside of the torsion tube and installed on the end fixing plate on the corresponding side.

[0011] The force transmission plate and the end fixing plate are respectively disposed at both ends of the torsion tube, and the bending moment resisting plate is disposed between the force transmission plate and the end fixing plate; or there are two end fixing plates, the two end fixing plates are respectively disposed at both ends of the torsion tube, the force transmission plate is disposed in the middle of the torsion tube, and the bending moment resisting plate is disposed between the force transmission plate and the end fixing plate.

[0012] It also includes a guide assembly, which includes two symmetrically arranged guide plates and a guide frame sleeved on the two guide plates; one end of the guide plate is fixed to one of the connecting rod assemblies, and the other end of the guide plate is connected to the other connecting rod assembly through the guide frame, and the guide frame is fixed to the corresponding connecting rod assembly.

[0013] The torsion tube energy dissipation components are in two sets, and the two sets of torsion tube energy dissipation components are arranged symmetrically perpendicular to the central axis of the connecting rod assembly.

[0014] The central axes of the two sets of connecting rod assemblies are parallel to each other and do not coincide. The middle part of the torsion tube is vertically fixed to one end of the corresponding connecting rod assembly. The fixing component and the bending moment resisting component are integrated on the same component, which includes two bending moment resisting tubes sleeved outside the corresponding torsion tubes and a tube body fixing plate that fixes the two bending moment resisting tubes. The two ends of the torsion tube are fixedly connected to the bending moment resisting tubes, and the middle part of the bending moment resisting tubes can rotate relative to the bending moment resisting tubes. The tube body fixing plate is perpendicular to the connecting rod assembly.

[0015] There are two tube fixing plates. The middle part of the twisted tube is connected to the corresponding connecting rod assembly through a horizontal connecting rod. The two tube fixing plates are symmetrically arranged at both ends of the horizontal connecting rod along the axial direction of the twisted tube. Each bending moment tube includes two bending moment sections, which are symmetrically arranged on the outside of the tube fixing plate.

[0016] The torsion tube includes a plastic deformation zone and a fixed connection zone. The connection positions of the connecting rod assembly and the fixed component with the torsion tube are located in the fixed connection zone. The diameter of the plastic deformation zone is smaller than the diameter of the fixed connection zone.

[0017] Compared with the prior art, the advantages of the present invention are as follows:

[0018] This invention includes a moment-resisting component and a fixing component. The moment-resisting component is sleeved around the torsion tube, and the torsion tube can rotate relative to the moment-resisting component. The moment-resisting component restricts the bending freedom of the torsion tube and can withstand the shear force during torsion, thus ensuring that the torsion tube only undergoes torsional deformation and not bending deformation. This improves the buckling strength and fatigue life of the torsion tube, thereby increasing the energy dissipation, vibration reduction, and reliability of the component, and extending its service life. Simultaneously, the two torsion tubes are fixedly connected to each other by the fixing component, forming a torsion fixing point to ensure effective torsional energy dissipation. Furthermore, the two torsion tubes are fixed by the same fixing component, resulting in a simple, compact, and low-cost structure. Attached Figure Description

Detailed Implementation

[0034] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments, but this does not limit the scope of protection of the present invention.

[0035] Example 1

[0036] Figures 1 to 6 An embodiment of the torsional energy dissipation support device of the present invention is shown, which can be applied to vibration reduction and energy dissipation in structures such as bridges and buildings, for example, for use in Figure 7 and Figure 11The frame structure shown may be either two relatively independently arranged structures 4 to be vibration-damped, or similar. The torsional energy-dissipating support device of the present invention includes a torsion tube energy-dissipating component 1 and two sets of connecting rod assemblies 2. The two sets of connecting rod assemblies 2 are respectively connected to the structures 4 to be vibration-damped. The centerline of the connecting rod assembly 2 is arranged according to the load direction of the structure 4 to be vibration-damped, that is, ensuring that the connecting rod assembly 2 is arranged along the load direction of the structure 4 to be vibration-damped. The torsion tube energy-dissipating component 1 is disposed between the two sets of connecting rod assemblies 2 to transfer the vibration energy of the structure 4 to be vibration-damped to the torsion tube energy-dissipating component 1 for vibration damping and energy dissipation.

[0037] In this embodiment, the torsion tube energy dissipation component 1 includes two torsion tubes 11, a bending moment resisting component 12, and a fixing component 13. The two torsion tubes 11 are respectively connected to corresponding connecting rod assemblies 2. The bending moment resisting component 12 is sleeved on the outside of the torsion tubes 11, and the torsion tubes 11 can rotate relative to the bending moment resisting component 12. The setting of the bending moment resisting component 12 restricts the degrees of freedom of the torsion tubes 11 except for rotation, and can withstand the shear load when the torsion tubes 11 are torsional, thus causing the torsion tubes 11 to only undergo torsional deformation and not bending deformation. This improves the buckling strength and fatigue life of the torsion tubes 11, thereby improving the energy dissipation and vibration reduction effect and reliability of the component, and also increasing the service life of the component. Meanwhile,

[0038] The two torsion tubes 11 are fixedly connected to each other by the fixing component 13. That is, the fixing component 13 is simultaneously fixedly connected to the outer side wall of the two torsion tubes 11, which forms the torsion fixing point of the torsion tubes 11 to ensure the effective torsion energy dissipation of the torsion tubes 11. Moreover, the two torsion tubes 11 are fixed by the same fixing component 13, which makes the structure simple, compact and low in cost.

[0039] Furthermore, the central axes of the two sets of connecting rod assemblies 2 coincide, and the torsion tube 11 is located on the outside of the corresponding connecting rod assembly 2; both sets of connecting rod assemblies 2 are connected to the torsion tube 11 on the corresponding side through a force transmission assembly 14, and the two sets of force transmission assemblies 14 are symmetrically arranged along the length direction of the connecting rod assembly 2. The symmetrical arrangement can increase the stability of the component structure itself, and while ensuring the effective transmission and dissipation of vibration energy, the structure is simple, compact, and low in cost.

[0040] Furthermore, such as Figures 2 to 6As shown, the force transmission assembly 14 includes a force transmission shaft 141 and a force transmission plate 142. The connecting rod assembly 2, the force transmission shaft 141, and the force transmission plate 142 are hinged in sequence, and the force transmission plate 142 is fixedly connected to the torsion tube 11. When the structure 4 to be damped vibrates, it starts to drive the connecting rod assembly 2, the force transmission shaft 141, and the force transmission plate 142 to rotate in sequence. At this time, the two torsion tubes 11 can rotate outward or inward synchronously. At this time, even when only one set of connecting rod assemblies 2 vibrates, it can also drive the two torsion tubes 11 to twist simultaneously, which greatly improves the vibration damping and energy dissipation effect. Meanwhile, since the end fixing plate 131 is fixed to the torsion tube 11, the torsional deformation zone of the torsion tube 11 undergoes torsional deformation under the force of the force transmission plate 142, thereby dissipating vibration energy. Simultaneously, the force transmission plate 142 and the fixing component 13 are perpendicular to each other to ensure consistent tensile and compressive forces on the component. This gives the component symmetrical force recovery characteristics, meaning that the torsion angle generated by the torsion tube 11 is the same when the tensile and compressive strokes are the same. Therefore, the vibration energy consumed by the torsion tube 11 during tensile and compressive energy dissipation is the same, reducing the risk of component failure and improving the component's safety and reliability. Specifically:

[0041] like Figure 12 As shown, l is the length of the connecting rod assembly 2; L is the distance from the center of the component to the end point in the initial working condition; h is the distance from the center of the torsion tube 11 to the center of the component; H is the torsional arm of the torsion tube 11 in the initial working condition; H1 is the torsional arm of the torsion tube 11 in the compression condition; H2 is the torsional arm of the torsion tube in the tension condition; θ is the distance between the connecting rod assembly 2 and the torsion tube connector in the initial working condition. Figure 1 Force transmission plate 142 or Figure 9 The included angle of the tube fixing plate 17); θ1 is the included angle between the connecting rod assembly 2 and the torsion tube connector under compression conditions; θ2 is the included angle between the connecting rod assembly 2 and the torsion tube connector under tension conditions; Δx is the compression or tension stroke of the two ends of the component.

[0042] When the force transmission plate 142 and the fixed component 13 are perpendicular to each other, h is half the center distance of the corresponding torsion tubes 11 of the two sets of connecting rod assemblies 2, and the torsional arm H is perpendicular to the connecting rod assembly 14. At this time, θ = 90°; H = 2h·sinθ; 2h = H. When θ = 90°, the torsional arm H of the torsion tube 1 is the largest. The torsional arm H decreases under compression and tension conditions, which constitutes the prerequisite for tension-compression symmetry.

[0043] During compression:

[0044]

[0045]

[0046]

[0047] Under tensile conditions:

[0048]

[0049]

[0050]

[0051] Since the force transmission plate 142 and the fixed component 13 are perpendicular to each other, the tension and compression conditions are symmetrical. At this time:

[0052] H1=H2=2h·sinθ1=2h·sinθ2

[0053] sinθ1=sinθ2

[0054] cosθ1=-cosθ2

[0055]

[0056]

[0057] Δx, as the stroke of the component, is very small compared to the total length of the 2L component, thus... Approximately equal to -1, the value of θ is also basically equal under the same tension and compression stroke. Therefore, the component exhibits tension-compression symmetry characteristics in actual working conditions.

[0058] like Figure 1 and Figure 5 As shown, the fixing component 13 includes an end fixing plate 131, which is fixedly connected to the torsion tube 11; the bending moment resisting component 12 includes a bending moment resisting plate 121, which is sleeved on the outside of the torsion tube 11, and the torsion tube 11 can rotate relative to the bending moment resisting plate 121. The bending moment resisting plate 121 bears the shear force when the torsion tube 11 is torsioned; the bending moment resisting plate 121 is installed on the end fixing plate 131 on the corresponding side through the connecting plate 15, which can form an integral torsion resisting fixing structure. While realizing the bending and torsional deformation resistance function of the torsion tube 11, it has the advantages of simple and compact structure and no need to occupy extra space.

[0059] Meanwhile, the end fixing plate 131 and the bending moment plate 121 ensure that the center distance between the two torsion tubes remains constant during vibration reduction and energy dissipation, thereby eliminating the tendency of the torsion tube 11 to move in other directions as much as possible and maintaining the state of full cross-section yielding, which improves the buckling strength and fatigue life of the torsion tube 11.

[0060] like Figure 3As shown, the force transmission plate 142 and the end fixing plate 131 are respectively disposed at both ends of the torsion tube 11, and the bending moment plate 121 is disposed between the force transmission plate 142 and the end fixing plate 131. This forms a fixed connection area 112 at both ends of the torsion tube 11 and a plastic deformation area 111 in the middle of the torsion tube 11. At this time, the middle of the torsion tube 11 can rotate freely when the structure 4 to be damped vibrates, while the two ends of the torsion tube 11 are fixed to form a torsion, which has high torsional reliability and ensures energy dissipation effect.

[0061] In other embodiments, such as Figure 8 As shown, the end fixing plate 131 can be configured as two, with the two end fixing plates 131 respectively disposed at both ends of the torsion tube 11, the force transmission plate 142 disposed in the middle of the torsion tube 11, and the bending moment plate 121 disposed between the force transmission plate 142 and the end fixing plate 131, which forms a fixed connection area 112 at both ends and the middle of the torsion tube 11, and a plastic deformation area 111 between adjacent fixed connection areas 112 of the torsion tube 11.

[0062] In this embodiment, there are two sets of torsion tube energy dissipation components 1, which are symmetrically arranged perpendicular to the central axis of the connecting rod assembly 2. This allows each connecting rod assembly 2 to connect two torsion tubes 11 for torsional energy dissipation, further improving the vibration reduction and energy dissipation effect of the structure 4 to be vibration-damped. Simultaneously, the symmetrical arrangement of the two sets of torsion tube energy dissipation components 1 perpendicular to the central axis of the connecting rod assembly 2 ensures high stability and reliability of the components. In other embodiments, the torsion tube energy dissipation components 1 can also be configured as a single set.

[0063] like Figure 1 and Figure 2 As shown, the torsional energy dissipation support device also includes a guide assembly 3, which includes a guide frame 32 and two guide plates 31. The two guide plates 31 are symmetrically arranged on the outer wall of the connecting rod assembly 2, with one end of each guide plate 31 fixed to one of the connecting rod assemblies 2, and the other end connected to the other connecting rod assembly 2 via the guide frame 32. The guide frame 32 is sleeved on the two guide plates 31, and can slide relative to the guide plates 31. The guide frame 32 is fixed to the corresponding connecting rod assembly 2. This arrangement of the guide plates 31 and guide frames 32 allows the connecting rods of the two sets of connecting rod assemblies 2 to move relative to each other and always remain on the same straight line, increasing the component's resistance to instability and ensuring reliable and safe operation. In other embodiments, such as... Figure 5 and Figure 6 As shown, the torsional energy dissipation support device may not need to be equipped with guide component 3, as long as the vibration energy can be reliably and stably transmitted.

[0064] Furthermore, the drive shafts corresponding to the two sets of connecting rod assemblies 2 pass through the guide plate 31, which has a circular hole and an oblong hole. One drive shaft passes through the circular hole to facilitate its installation and ensure effective vibration transmission. The oblong hole is arranged along the axial movement direction of the connecting rod assembly 2, and its length is the preset axial distance of the corresponding connecting rod assembly 2. The other drive shaft passes through the oblong hole to facilitate its installation, ensure effective vibration transmission, and prevent motion interference between the two sets of connecting rod assemblies 2.

[0065] In this embodiment, the torsion tube 11 includes a plastic deformation zone 111 and a fixed connection zone 112. The connection points of the connecting rod assembly 2 and the fixing component 13 with the torsion tube 11 are located in the fixed connection zone 112. The diameter of the plastic deformation zone 111 is smaller than the diameter of the fixed connection zone 112, so that the plastic deformation zone 111 of the torsion tube 11 undergoes plastic deformation under the force of the connecting rod assembly 2, dissipating vibration energy. The connecting rod assembly 2 and the fixing component 13 are connected to the fixed connection zone 112 by means of welding, bonding, or spline connection.

[0066] In this embodiment, the torsion tube 11 is a hollow shaft. Since the area where the torsion tube 11 undergoes plastic deformation is mainly the outer periphery of the torsion tube 11, the hollow shaft design saves costs. In other embodiments, the torsion tube 11 can also be a solid shaft.

[0067] In this embodiment, the working process of the torsional energy dissipation support device is as follows: When the structure 4 to be vibration damped is relatively close, the two sets of connecting rod assemblies 2 are also relatively close. At this time, the torsion tubes 11 corresponding to the two sets of connecting rod assemblies 2 are relatively far apart under the action of the force transmission component 14, and each torsion tube 11 is forced to generate plastic torsion, dissipating the vibration energy of the structure, thereby achieving the purpose of suppressing structural vibration. When the structure 4 to be vibration damped is relatively far apart, the two sets of connecting rod assemblies 2 are also relatively far apart, and the torsion tubes 11 corresponding to the two sets of connecting rod assemblies 2 are relatively close, and energy can also be dissipated through the plastic torsion of the torsion tubes 11.

[0068] Example 2

[0069] Figures 8 to 11 Another embodiment of the torsional energy dissipation support device of the present invention is shown. This embodiment is basically the same as the previous embodiment, except that the central axes of the two sets of connecting rod assemblies 2 are parallel to each other and do not coincide. The middle part of the torsion tube 11 is directly and vertically fixed to one end of the corresponding connecting rod assembly 2. The fixing component 13 and the bending moment resisting component 12 are integrated on the same component, which includes two bending moment resisting tubes 16 and a tube body fixing plate 17. The two bending moment resisting tubes 16 are sleeved on the corresponding torsion tubes 11. The two ends of the torsion tube 11 are fixedly connected to the bending moment resisting tubes 16. The middle part of the bending moment resisting tube 16 can rotate relative to the bending moment resisting tube 16. At this time, when the structure 4 to be damped vibrates, the middle part of the torsion tube 11 can rotate freely, while the two ends are fixed to form torsional energy dissipation.

[0070] In this embodiment, the moment-resisting tube 16 restricts the bending freedom of the torsion tube 11 and can withstand the shear force when the torsion tube 11 is torn, so that the torsion tube 11 only undergoes torsional deformation and does not undergo bending deformation. At the same time, when the connecting rod assembly 2 drives the torsion tube 11 to twist, the force will also be transmitted to the moment-resisting tube 16 fixedly connected to both ends of the torsion tube 11. At this time, the moment-resisting tube 16 will rotate with the torsion tube 11 to a certain extent, which has a certain auxiliary energy dissipation effect.

[0071] In this embodiment, two moment-resisting tubes 16 are fixedly connected by a tube body fixing plate 17. At this time, the two torsion tubes 11 are finally fixed by the same tube body fixing plate 17, which ensures that the center distance between the two torsion tubes 11 remains unchanged when the torsion energy is dissipated. This allows the torsion tubes 11 to eliminate the tendency of movement in other directions as much as possible and maintain the state of full cross-section yielding, which improves the buckling strength and fatigue life of the torsion tubes 11. Moreover, the structure is simple, compact and low in cost.

[0072] Meanwhile, the tube fixing plate 17 and the connecting rod assembly 2 are perpendicular to each other, which makes the component have symmetrical force recovery characteristics under tension and compression. That is, the torsion angle generated by the torsion tube 11 is the same when the tension and compression strokes are the same. At this time, the vibration energy consumed by the torsion tube 11 under tension and compression is the same, which reduces the risk of component failure and improves the safety and reliability of the component.

[0073] Furthermore, there are two tube fixing plates 17. The middle part of the torsion tube 11 is connected to the corresponding connecting rod assembly 2 through a horizontal connecting rod 18. The two tube fixing plates 17 are symmetrically arranged at both ends of the horizontal connecting rod 18 along the axial direction of the torsion tube 11. Each moment-resisting tube 16 includes two moment-resisting sections, which are symmetrically arranged on the outside of the tube fixing plate 17. This achieves reliable torsional energy dissipation of the components, and the structure is simple, compact, and occupies little space.

[0074] In this embodiment, the working process of the torsional energy dissipation support device is as follows: When the structure 4 to be vibration-damped is relatively close, the two sets of connecting rod assemblies 2 drive the torsion tubes 11 to be relatively close. At this time, the torsion tubes 11 corresponding to the two sets of connecting rod assemblies 2 generate plastic torsion under the action of the cross link 18, dissipating the vibration energy of the structure and achieving the purpose of suppressing structural vibration. When the structure 4 to be vibration-damped is relatively far away, the two sets of connecting rod assemblies 2 drive the torsion tubes 11 to be relatively far away, and energy can also be dissipated through the plastic torsion of the torsion tubes 11.

[0075] Although the invention has been described with reference to preferred embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the invention. In particular, the technical features mentioned in the various embodiments can be combined in any manner as long as there is no structural conflict. The invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
