Description

Technical Field

[0001] This invention relates to the field of damping wall technology, and in particular to a novel high-performance viscous damping wall. Background Technology

[0002] Damped walls, also known as damper walls or energy dissipation walls, are efficient passive control devices used in modern high-rise buildings, long-span bridges, and other important structures to resist wind loads and seismic forces. Their core function is to dissipate the energy input to the structure, reducing vibration and deformation, thereby improving structural comfort and safety.

[0003] In existing technologies, such as the multi-layer viscous damping wall disclosed on the Chinese patent website with publication number CN 113356663 B, although the multi-layer viscous effect can be achieved by utilizing the gap between the energy-dissipating plate and the clamping plate, it still has the following shortcomings:

[0004] 1. When multiple connecting plates and energy-dissipating plates are placed together to achieve a sticky effect, they must have strong compressive strength and toughness. This makes it possible to choose metal plates as the material for the plates. The adhesion between the metal plates and the viscous liquid directly affects the damping effect of the damping wall. In the existing technology, the metal plates are chosen to be planes that are parallel to the main damping direction. The damping force relies entirely on the adhesion between the viscous liquid and the energy-dissipating plates and clamps. However, when encountering moderate or large earthquakes, especially when the vibration is continuous for a long time, the temperature inside the viscous liquid will inevitably rise during the back-and-forth vibration, adhesion, and stretching deformation. If the temperature of the viscous liquid cannot be discharged in a short time and causes accumulation, it will inevitably weaken the adhesion between the viscous liquid and the surface of the metal plate, thus weakening the sticky effect of the sticky wall.

[0005] 2. The bottom of the multiple connecting plates is arranged in a fixed array. However, when the adhesive wall is actually used, the direction of the vibration force it receives is three-dimensional. This means that during vibration damping, the transverse direction will also generate a transverse force due to instantaneous acceleration. However, in the existing technology, the connecting plates and energy-consuming plates are fixed in the transverse direction. The transverse vibration generated will directly act on the surface of the plate after the viscous liquid is absorbed. At this time, the middle surface of the plate and the edge are fixed to the surface of the channel steel. Due to the different fixing positions with the channel steel, the deformation degree of the middle surface of the energy-consuming plate and the connecting plate is different from that of the edge. Finally, the energy-consuming plate and the connecting plate will deform. Summary of the Invention

[0006] Based on existing technical problems, this invention proposes a novel high-performance viscous damping wall.

[0007] The present invention proposes a novel high-performance viscous damping wall, comprising a channel steel box for loading viscous liquid and connected to a damper connecting wall pier, and a damping body placed vertically inside the channel steel box and connected to the damper connecting wall pier.

[0008] The channel steel box has multiple metal plates arranged in an array in the vertical direction. The inner bottom of the channel steel box has anti-deformation mechanisms that are movably sleeved with the bottom ends of the metal plates. When an earthquake occurs, the damping body moves back and forth along the length of the damper connecting wall pier through the viscous fluid and acts on the surface of the metal plate. At the same time, it is driven by the anti-deformation mechanism to perform a reciprocating elastic buffering action along the thickness direction of the damper connecting wall pier.

[0009] Both the damping body and the metal plate have an array of outwardly protruding adhesion-enhancing mechanisms on their surfaces to increase the bonding area. When vibration occurs, the viscous liquid adheres to the adhesion-enhancing mechanisms for damping.

[0010] Preferably, the damping body includes a mounting plate, the upper surface of which is fixedly connected to the embedded part at the bottom of the upper damper connecting wall pier, and the lower surface of the channel steel box is fixedly connected to the embedded part at the top of the lower damper connecting wall pier.

[0011] Preferably, the lower surface of the mounting plate is fixedly mounted with adhesive plates that are staggered and evenly spaced from the metal plate.

[0012] Preferably, the anti-deformation mechanism includes a support shaft installed on the inner bottom sides of the channel steel box, and the bottom ends of the plurality of metal plates are movably sleeved on the surface of the support shaft to realize the sliding action of the plurality of metal plates along the axial direction of the support shaft.

[0013] The above technical solution can achieve both evenly spaced metal plates and overall elastic sliding effect.

[0014] Preferably, the surface of the support shaft is movably sleeved with disc springs that are equally spaced from the side of the metal plate, and multiple sets of disc springs elastically clamp multiple metal plates.

[0015] The above technical solution enables all metal plates to move elastically in a coordinated manner, avoiding deformation problems caused by direct rigid contact.

[0016] Preferably, the adhesive-enhancing mechanism consists of a riveting adhesive-enhancing device or an elastic adhesive-enhancing device;

[0017] The riveting and adhesion enhancement device increases the contact area with the viscous liquid by riveting the metal plate and the adhesive plate to make them bulge outward.

[0018] The elastic thickening device uses lateral elastic deformation to cause the metal plate and the viscous plate to bulge outward elastically, thereby increasing the contact area with the viscous liquid.

[0019] Preferably, the riveting and bonding device includes an array of spherical shells fixed to both sides of the metal plate and the adhesive plate, wherein the edges of the spherical shells are fixed to the surfaces of the metal plate and the adhesive plate by welding;

[0020] After the inner wall of the spherical shell is fixed to one side of the metal plate and the adhesive plate by riveting, the riveting head extends to the other side to form a spherical shape.

[0021] Through the above technical solution, the spherical shape of the shell can increase the lateral contact area with the viscous liquid.

[0022] Preferably, the surface of the spherical shell is provided with a viscous hole, and the edges of both ends of the viscous hole are rounded.

[0023] By using the above technical solution, the rounded corners at both ends of the viscous hole can prevent burrs or right angles at the edge of the viscous hole from cutting the viscous liquid, thereby avoiding weakening the viscous effect of the viscous liquid.

[0024] Preferably, the elastic adhesion device includes two disc springs arranged in a rectangular array that penetrate the surfaces of the metal plate and the adhesive plate, and the end faces of the disc springs are attached to the side surfaces of the metal plate and the adhesive plate and elastically deform along the center line direction.

[0025] The axis of the disc spring 2 is connected to the surface of the metal plate and the adhesive plate through a tensile shaft, and the two ends of the tensile shaft are also fitted with anti-shear sleeves.

[0026] Through the above technical solution, the disc spring can be matched with a suitable size and model of elastic force according to the specific vibration magnitude, and the anti-shear sleeve can prevent excessive viscous fluid force from causing shear deformation against the pull shaft.

[0027] Preferably, the adaptive module includes a lifting hydraulic cylinder mounted on the upper surface of the damper connecting wall pier, and an electro-hydraulic servo valve for controlling flow and pressure is fixedly installed at the oil port of the lifting hydraulic cylinder. Vibration sensors electrically connected to the electro-hydraulic servo valve are also installed on the surfaces of the metal plate and the viscous plate.

[0028] The vibration sensor transmits the detected seismic data to the neural network to intelligently control the flow rate and pressure of the electro-hydraulic servo valve to the lifting hydraulic cylinder, thereby generating the target damping force and adjusting the viscosity depth.

[0029] The beneficial effects of this invention are as follows:

[0030] 1. By setting up an anti-deformation mechanism, when the damping wall is subjected to vibration in different directions or the instantaneous vibration deformation force is too large, the metal plate can be elastically displaced in the thickness direction of the channel steel box in time, so as to avoid the problem of deformation caused by the rigid contact between the metal plate and the damping body.

[0031] 2. By setting up a viscosity-enhancing mechanism, the viscous area and viscous force of the viscous liquid in the horizontal direction can be increased, preventing the viscous liquid from accumulating and weakening the viscous wall's adhesion effect due to its inability to dissipate quickly.

[0032] 3. By setting up a neural network to process seismic data and automatically adjusting the depth of the damper inserted into the viscous fluid, the viscous damper can achieve intelligent control to adapt to different seismic environments and also has the effect of fine-tuning the installation height.

Detailed Implementation

[0045] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0046] Reference Figures 1-11 A novel high-performance viscous damping wall, such as Figures 1-2 As shown, it includes a channel steel box 2 for loading viscous liquid 1 and disposed between the upper and lower damper connecting wall blocks 8, and a damping body 3 placed vertically inside the channel steel box 2 and connected to the damper connecting wall blocks 8.

[0047] The damping body 3 is installed as follows: Figure 3 As shown, the damping body 3 includes a mounting plate 31. The upper surface of the mounting plate 31 is fixedly connected to the embedded part at the bottom of the upper damper connecting wall pier 7, and the lower surface of the channel steel box 2 is fixedly connected to the embedded part at the top of the lower damper connecting wall pier 7.

[0048] Furthermore, an adhesive plate 32 is fixedly installed on the lower surface of the mounting plate 31, which is staggered and equally spaced from the metal plate 4.

[0049] In order to avoid the problem of damping walls easily deforming under lateral forces during moderate or large earthquakes, such as Figure 3 As shown, multiple metal plates 4 are arranged in an array in the vertical direction of the channel steel box 2. The inner bottom ends of the channel steel box 2 are provided with anti-deformation mechanisms that are movably sleeved with the bottom ends of the metal plates 4. When an earthquake occurs, the damping body 3 moves back and forth along the length direction of the damper connecting wall pier 8 through the viscous fluid and acts on the surface of the metal plate 4. At the same time, it is driven by the anti-deformation mechanism to perform a reciprocating elastic buffering action along the thickness direction of the damper connecting wall pier 8.

[0050] The anti-deformation mechanism specifically prevents the damping wall from deforming in the following way: Figures 3-4 As shown, the anti-deformation mechanism includes support shafts 7 installed on the inner bottom sides of the channel steel box 2. The bottom ends of multiple metal plates 4 are movably sleeved on the surface of the support shafts 7, enabling the multiple metal plates 4 to slide along the axial direction of the support shafts 7. This achieves both equidistant spacing of the metal plates 4 and overall elastic sliding.

[0051] Furthermore, disc springs 71, evenly spaced from the sides of the metal plates 4, are movably sleeved on the surface of the support shaft 7. Multiple sets of disc springs 71 elastically clamp multiple metal plates 4. This allows all metal plates 4 to move elastically in a coordinated manner, avoiding deformation problems caused by direct rigid contact.

[0052] By setting up an anti-deformation mechanism, when the damping wall is subjected to vibration in different directions or the instantaneous vibration deformation force is too large, the metal plate 4 can be elastically displaced along the thickness direction of the channel steel box 2 in a timely manner, thus avoiding the problem of deformation caused by rigid contact between the metal plate 4 and the damping body 3.

[0053] To prevent the viscous fluid from overheating and weakening its damping effect during moderate or large earthquakes, such as... Figure 4 As shown, the surfaces of the damping body 3 and the metal plate 4 are arrayed with outwardly protruding adhesion-enhancing mechanisms to increase the adhesion area. When vibrating, the viscous liquid 1 adheres to the adhesion-enhancing mechanisms for damping.

[0054] Specifically, this is how viscosity enhancement is achieved: (e.g.) Figure 4 , Figure 5 as well as Figure 7 As shown, the adhesive enhancement mechanism consists of a riveting adhesive enhancement device or an elastic adhesive enhancement device;

[0055] The riveting and adhesion enhancement device increases the contact area with the viscous liquid 1 by riveting the metal plate 4 and the adhesive plate 32 to make them protrude outward.

[0056] The elastic thickening device uses lateral elastic deformation to make the metal plate 4 and the adhesive plate 32 bulge outward elastically, thereby increasing the contact area with the viscous liquid 1.

[0057] Among them, such as Figures 5-6 As shown, the riveting and bonding device includes an array of spherical shells 5 fixed to the two sides of the metal plate 4 and the adhesive plate 32. The edges of the spherical shells 5 are fixed to the surfaces of the metal plate 4 and the adhesive plate 32 by welding.

[0058] The inner wall of the spherical shell 5 is fixed to one side of the metal plate 4 and the viscous plate 32 by riveting, and the riveting head extends to the other side to form a spherical shape. The spherical shape of the spherical shell 5 can increase the lateral contact area with the viscous liquid.

[0059] Preferably, the surface of the spherical shell 5 is provided with a viscosity hole 51, and both ends of the viscosity hole 51 are rounded. The rounded edges at both ends of the viscosity hole 51 can prevent burrs or right angles at the edges of the viscosity hole 51 from cutting the viscous liquid, thereby avoiding weakening the viscosity effect of the viscous liquid.

[0060] When the viscous liquid is pulled upwards, a portion of the viscous liquid inside the spherical shell 5 is blocked by the inner wall of the spherical shell 51, and adheres to the viscous liquid inside the viscous pore 51, resulting in a pulling effect and achieving the thickening effect on the inner wall of the spherical shell 5 in one step. At the same time, when the outer surface of the spherical shell 5 is pulled while adhering to the viscous liquid, the original shape of the spherical shell 5 also increases the adhesion area with the viscous liquid, further enhancing the thickening effect.

[0061] Among them, such as Figures 7-9 As shown, the elastic adhesion-enhancing device includes disc springs 6 arranged in a rectangular array penetrating the surfaces of the metal plate 4 and the adhesive plate 32. The end faces of the disc springs 6 are attached to the side surfaces of the metal plate 4 and the adhesive plate 32, and elastically deform along the centerline. The size and model of the disc springs 6 can be selected according to the specific vibration magnitude to provide appropriate elasticity.

[0062] Furthermore, the axis of the disc spring 6 is connected to the surface of the metal plate 4 and the adhesive plate 32 through a tensile shaft 61. Shear sleeves 62 are fitted onto both ends of the tensile shaft 61. The shear sleeves 62 prevent excessive viscous fluid force from causing shear deformation of the tensile shaft 61. In particular, the gap between the bottom of the disc spring 6 and the metal plate 4 will shear the tensile shaft 61 upwards.

[0063] When the viscous liquid is squeezed, it will simultaneously squeeze the disc spring 6, causing compression deformation and preventing deformation of the side surface of the metal plate 4 or the viscous plate 32.

[0064] When the viscous liquid is stretched, it will simultaneously stick to the disc spring 6, causing it to stretch outward and preventing deformation of the side surface of the metal plate 4 or the viscous plate 32.

[0065] By setting up a viscosity-enhancing mechanism, the viscous area and viscous force of the viscous liquid in the horizontal direction can be increased, preventing the viscous liquid from accumulating and weakening the viscous effect of the viscous wall due to its inability to dissipate quickly.

[0066] like Figures 2-4 as well as Figures 10-11As shown, the lower surface of the channel steel box 2 is provided with an adaptive module for adjusting the viscous depth. The adaptive module automatically adjusts the depth of the damping body 3 inserted into the viscous fluid after processing the collected seismic data through a neural network, so as to adapt to different seismic environments.

[0067] Specifically, it is implemented as follows: the adaptive module includes a lifting hydraulic cylinder 21 installed on the upper surface of the damper connecting wall pier 8, and an electro-hydraulic servo valve 22 for controlling flow and pressure is fixedly installed at the oil port of the lifting hydraulic cylinder 21. Vibration sensors 23 electrically connected to the electro-hydraulic servo valve 22 are also installed on the surfaces of the metal plate 4 and the adhesive plate 32.

[0068] The vibration sensor 23 transmits the detected earthquake data to the neural network to intelligently control the flow rate and pressure of the electro-hydraulic servo valve 22 to the lifting hydraulic cylinder 21, thereby generating the target damping force and adjusting the viscosity depth.

[0069] Specifically, the neural network intelligently controls the lifting hydraulic cylinder 21 as follows:

[0070] S1. Constructing vibration sensing data control signals Damping force Mathematical model of structural response

[0071] The mathematical model is based on the clipped-optimal algorithm: first, an ideal optimal damping force is designed. Then, based on the physical characteristics of the lifting hydraulic cylinder 21, the control signal is adjusted. This causes the actual force generated by the lifting hydraulic cylinder 21 to... as close as possible .

[0085] Performance evaluation: Evaluate the accuracy of the predictive control signal on the test set. More importantly, conduct numerical simulations: Connect the trained neural network controller to the system model (or a higher fidelity simulation model, such as a Simulink model) established in the second step, run a completely new seismic wave, and observe whether its control effect (such as top displacement and acceleration reduction rate) is superior to that of the lifting hydraulic cylinder 21.

[0094] e. Output and execution: The control signal is sent to the electro-hydraulic servo valve 22 to drive the lifting hydraulic cylinder 21, thereby changing the damping force of the viscous damper.

[0095] f. Wait for the next control cycle.

[0096] S6, Continuous Monitoring and Learning

[0097] After deployment on a real system, runtime data is continuously recorded.

[0098] If the control effect is found to be unsatisfactory or fails in new vibration modes, this new data can be collected to fine-tune the neural network, making it adaptable to a wider range of situations.

[0099] By setting up a neural network to process seismic data and automatically adjust the depth of the damper 3 inserted into the viscous fluid, the viscous damper can achieve intelligent control to adapt to different seismic environments and also has the ability to fine-tune the installation height.

[0100] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
