Description

Technical Field

[0001] The present invention relates to the technical field of building structure vibration control, in particular to a rolling passive tuned mass damper. Background Art

[0002] Passive tuned mass dampers (TMDs) are currently the primary method for controlling wind-induced vibrations in high-rise building structures. They require no external energy input and have a relatively simple structure. They have been used in real-world projects and have proven their effectiveness under conditions such as typhoons. Traditional TMDs are often pendulum-type. According to the formula for calculating the period of a pendulum-type TMD, its period is positively correlated with the rope length. However, high-rise buildings often have low first-order frequencies and long periods. Consequently, traditional pendulum-type TMDs require a longer pendulum length, which typically occupies a larger vertical space within the building, affecting building efficiency.

[0003] Therefore, some scholars have proposed a ball-rolling TMD device, which has more advantages in space utilization, structural installation, etc. When the natural vibration period of the TMD device is close to the natural vibration period of the building structure, it can achieve a good vibration reduction effect.

[0004] However, traditional rolling TMDs are mostly based on small-mass spheres, usually with a diameter of less than 0.2m. There are no large-scale centralized structures with each sphere exceeding 1m in diameter and weighing hundreds of tons. Traditional TMD devices based on small-mass spheres are insufficient to meet the requirements for controlling wind-induced vibrations in high-rise buildings due to their small total mass when placed in a centralized manner.

[0005] At the same time, the building's natural vibration period varies throughout its lifecycle. This can be caused by adjustments to the functional use of certain spaces or aging of structural components. Traditional rolling TMDs, however, have difficulty adjusting their natural vibration period to accommodate changes in the building's structural period. This can lead to "detuning" of the TMD, meaning the natural vibration period of the TMD differs significantly from that of the building structure, resulting in poor vibration reduction.

[0006] Therefore, there is an urgent need for a rolling passive tuned mass damper that can significantly improve the "detuning" of the traditional rolling TMD device and maintain the vibration reduction effect. At the same time, compared with the pendulum TMD, it occupies less vertical space in the building and can well meet the vibration reduction needs of high-rise buildings. Summary of the Invention

[0007] (1) Technical issues to be solved

[0008] In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides a rolling passive tuned mass damper, which solves the technical problem that the traditional rolling TMD is difficult to adjust the natural vibration period, which may cause the TMD device to be "detuned" and affect the vibration reduction effect.

[0012] The mass sphere is arranged to roll in a concave spherical track on the top of the first base;

[0019] The connecting device includes a cavity plate located in the middle and a telescopic rod arranged at the end of the cavity plate, and the protruding end of the telescopic rod is connected to the slider to enable the cavity plate to move relative to the slider.

[0020] A through hole for passing the mass sphere is provided in the middle of the cavity plate. The cavity plate is sleeved in the middle of at least one of the mass spheres. The cavity plate and the center of each mass sphere are located in the same horizontal plane.

[0021] The second base includes a concrete base and a slide rail support fixedly arranged on the top of the concrete base, and a slide rail is provided between the slide rail supports;

[0022] The two fixed blocks are fixed on the top of the concrete base and are located below the slide rail;

[0023] The slide rail passes through the slider and is slidably connected to the slider.

[0024] The bottom of the sliding block is provided with a protrusion for passing through the fixed stopper, and the middle of the fixed stopper is provided with a second through slot, and the protrusion matches the second through slot.

[0025] Second limiting plates are fixedly provided at both ends of the spring, and the second limiting plates cooperate with the fixed stoppers to keep the spring between the two fixed stoppers.

[0027] A first limiting plate is provided along the edge of the first base, and the first limiting plate is used to limit the displacement of the mass sphere.

[0028] (3) Beneficial effects

This achieves tuning of the rolling passive tuned mass damper, making the vibration reduction effect of the rolling passive tuned mass damper more stable. BRIEF DESCRIPTION OF THE DRAWINGS

[0050] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below with reference to the accompanying drawings and through specific embodiments. Figure 1 The orientation is referenced.

[0051] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. Instead, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0052] See attached Figure 1 As shown, the present invention provides a rolling passive tuned mass damper, comprising: a mass sphere 1, a first base 3, a second base 2, a force transmission assembly and a connecting device 7. The first base 3 is fixed on the plane of the building structure. A plurality of spherical concave tracks 31 are provided on the top of the first base 3. The mass sphere 1 can be rolled in the spherical concave tracks 31. The second base 2 is fixedly arranged in pairs on the outer edge of the first base 3 along the first direction and the second direction, respectively, wherein the first direction is perpendicular to the second direction. The bottom of the second base 2 is fixedly connected to the building structure. The connecting device 7 is horizontally sleeved on the middle part of the mass sphere 1, that is, the connecting device 7 is sleeved on the horizontal plane position at the center of the sphere when the mass sphere 1 is placed at the lowest point of the spherical concave track 31. The connecting device 7 is connected to the force transmission assembly. The force transmission assembly includes a spring 4, a damping member 5 and a slider 6. The slider 6 is slidably arranged on the top of the second base 2. A first through groove 61 is provided at the bottom of the slider 6. A detachable spring 4 is provided in the first through groove 61. A fixed stopper 24 for limiting the spring 4 is provided on the second base 2. The slider 6 cooperates with the fixed stopper 24 to squeeze the spring 4, thereby generating a spring restoring force.

[0053] When the building structure vibrates, the mass sphere 1 is displaced in a certain direction with the vibration. The connecting device 7 constrains the mass sphere 1 during the rolling process of the mass sphere 1, so that multiple mass spheres 1 act in coordination. At the same time, the mass sphere 1 rolls and drives the connecting device 7, which pushes the slider 6 to produce horizontal displacement. The spring 4 and the damping element 5 give the slider 6 a reverse force and transmit the force to the second base 2. The second base 2 then transmits the corresponding force to the building structure to achieve the effect of vibration reduction.

[0054] Thanks to the connection device 7 that constrains the sphere's motion, the sphere's vertical displacement is eliminated, and the horizontal displacement of the slider 6 is consistent with that of the mass sphere 1. By providing the slider 6 as a force transmission carrier, the mass sphere 1 is subjected to the forces of the spring 4 and the damper 5 during rolling. The spring 4 is removable and replaceable, allowing the rolling damper to adjust its spring stiffness by replacing the spring 4 according to changes in the building structure's usage, thereby achieving tuning of the rolling passive tuned mass damper. By connecting the damper 5 between the slider 6 and the second base 2, the vibration damping effect of the rolling passive tuned mass damper is further stabilized.

[0055] See attached Figure 3 As shown, the first base 3 serves as the middle base of the rolling passive tuned mass damper, which is used to cooperate with the mass sphere 1 to provide a rolling track for the mass sphere 1. A first limit plate 32 is provided along the edge of the first base 3 to prevent the mass sphere 1 from rolling out of the concave ball track 31 due to excessive travel.

[0056] The mass spheres 1 are arrayed on the spherical concave track 31 , and the mass spheres 1 correspond to the spherical concave track 31 one by one. The mass spheres 1 are mass spheres with a spherical appearance after assembly.

[0057] The number of spherical concave tracks 31 can be determined according to the horizontal space of the building, and can be 1, 2×2, or 2×3. However, the distribution pattern must be a rectangular array. Figure 3 , attached Figure 3 The first base 3 uses four ball concave tracks 31. When the number of mass balls 1 arrayed along the first direction and along the second direction is different, the sizes of the second base 2, the force transmission component and the cavity plate 72 can be adjusted accordingly.

[0058] See attached Figure 7 As shown, the connecting device 7 has a frame structure and is used to constrain the mass spheres 1. When there are multiple mass spheres 1, the connecting device 7 can constrain multiple mass spheres 1 while ensuring that the individual mass sphere components move in coordination and function together. The connecting device 7 includes a cavity plate 72 located in the middle and a telescopic rod 71 disposed at the end of the cavity plate 72. The cavity plate 72 has a through hole in the middle for the mass spheres 1 to pass through, and the number of through holes is set according to the number of mass spheres 1. The size of the through hole matches the diameter of the mass spheres 1; in this embodiment, rectangular through holes are used. The cavity plate 72 is mounted in the middle of at least one mass sphere 1, and the center of each mass sphere 1 is located in the same horizontal plane. One end of the telescopic rod 71 is connected to the cavity plate 72, and the other end is connected to the side of the slider 6. The telescopic rod 71 is extended and retracted, allowing the cavity plate 72 to move relative to the slider 6, ensuring that the cavity plate 72 can move in the horizontal plane under the influence of the mass spheres 1.

[0059] When mass sphere 1 rolls within concave spherical track 31, its center of mass undergoes not only horizontal displacement but also vertical up-and-down displacement. However, as mass sphere 1 rolls and drives cavity plate 72, it only pushes it horizontally, while simultaneously producing a vertical relative displacement with the cavity plate 72. This means that the sphere only transmits the horizontal displacement of its center of mass to cavity plate 72, not the vertical displacement. Consequently, as mass sphere 1 rolls and pushes cavity plate 72, the vertical displacement of the sphere is eliminated, causing the horizontal displacement of slider 6 to align with that of mass sphere 1.

[0060] In addition, by setting up a structural form in which the mass sphere 1 acts in coordination, the traditional pendulum-type TMD device is replaced, so that the building space occupied by the entire device is smaller, thereby improving space utilization.

[0061] See attached Figure 2 As shown, the second base 2 is used to transmit the force of the spring 4 and the damping member 5 to the building structure, and the second base 2 is arranged corresponding to the four sides of the first base 3. There are four second bases 2 in this embodiment, one is placed on each side of the first base 3. The second base 2 includes a concrete base 23, a slide rail 21 fixedly arranged on the top of the concrete base 23, and a fixed stopper 24. The bottom of the concrete base 23 is fixedly connected to the building structure so that the force of the spring 4 and the damping member 5 can be transmitted to the building structure through the second base 2. The two ends of the slide rail 21 are fixedly connected to the concrete base 23 through the slide rail supports 22 respectively. The slide rail 21 passes through the slider 6 and is slidably connected to the slider 6. The two fixed stops 24 are symmetrically arranged relative to the center line of the concrete base 23.

[0062] See attached Figure 6 , Attachment Figure 8 As shown, the bottom of the slider 6 is provided with a first through slot 61, and a detachable spring 4 is provided in the first through slot 61. The spring 4 is provided between the two fixed blocks 24. Figure 4 As shown, second limiting plates 41 are fixedly provided at both ends of the spring 4. The second limiting plates 41 cooperate with the fixed stoppers 24 to retain the spring 4 between the fixed stoppers 24. A protrusion 62 is provided at the bottom of the slider 6 for passing through the fixed stoppers 24. A second through-slot is provided in the middle of the fixed stoppers 24, through which the protrusion 62 can pass, so that the fixed stoppers 24 limit the spring 4 without affecting the sliding of the slider 6.

[0063] In this embodiment, the distance between the two fixed blocks 24 is consistent with the length of the first through slot 61 .

[0064] One side of the slider 6 is fixed to the protruding end of the telescopic rod 71. When the telescopic rod 71 drives the slider 6 to move to one side, the second limit plate 41 on the side of the movement direction is blocked by the fixed stopper 24 and cannot move. The end of the slider 6 opposite to the movement direction squeezes the second limit plate 41 on the same side. At this time, the spring 4 is located between the side wall of the through groove of the slider 6 and the fixed stopper 24, thereby squeezing the spring 4, thereby generating a spring restoring force; when the slider 6 moves in the opposite direction, the second limit plate 41 on this side disengages from the slider 6, squeezing the second limit plate 41 at the other end, and so on.

[0065] In order to prevent the spring 4 from falling out of the first through slot 61 , a baffle may be optionally provided in the first through slot 61 .

[0066] The damping member 5 is arranged on one side of the slider 6. Figure 5 As shown, the damping element 5 includes a cylinder 51 and a piston 52. The piston 52 is retractably disposed within the cylinder 51. The fixed end of the cylinder 51 is fixedly connected to the slide rail support 22, and the extended end of the piston 52 is fixedly connected to the slider 6. The damping element 5 transmits the damping force to the mass sphere 1 through the slider 6, and simultaneously transmits it to the building structure through the second base 2, achieving a vibration reduction effect.

[0067] The upper portion of the slider 6 is connected to the telescopic rod 71, and the lower portion is provided with a slot that allows the fixed block 24 to pass through, while also driving the second limit plate 41 to compress the spring 4 to transmit the spring restoring force. The outer surface of the slider 6 is also connected to the damping element 5 to transmit the damping force. The slider 6 acts as a force transmission carrier, working in conjunction with the second base 2 and the connecting device 7 to transmit the damping force and the spring restoring force, achieving a vibration reduction effect.

[0068] like Figure 9 As shown in the figure, a 70-story shear wall structure subjected to a 50-year return period fluctuating wind load was used as an example. The acceleration response of the top floor of the structure was simulated using numerical simulation, and the corresponding time history curve was obtained. It was found that the device of the present invention significantly reduced the peak value of the acceleration response of the top floor of the structure, demonstrating the excellent vibration reduction performance of the device of the present invention.

[0069] like Figure 10 As shown in the figure, using the operating conditions of a 70-story shear wall structure subjected to fluctuating wind loads with a 50-year return period as an example, numerical simulations were conducted to simulate the acceleration response of the top floor of the structure under the control of the present invention's device and a conventional pendulum-type TMD of the same mass. The corresponding time history curves were compared and found to be very similar in terms of acceleration response and vibration reduction. Furthermore, the present invention's device occupies less than 3 meters of vertical space, while the conventional pendulum-type TMD occupies more than 7 meters of vertical space. Therefore, the present invention's device occupies even less vertical space in the building.

[0070] The present invention provides a rolling passive tuned mass damper, which replaces the traditional pendulum TMD device by arranging a structure in which multiple mass spheres 1 are matched with each other, saves vertical building space, improves space utilization, and solves the problem that the natural vibration period of the traditional rolling damper cannot be adjusted, thereby achieving the use requirement of controlling the peak vibration impact of high-rise building structures.

[0071] By providing a connection device 7 to constrain the mass spheres 1, it is possible to ensure that the multiple mass spheres 1 move in coordination and function together. As the mass spheres 1 roll and push the cavity plate 72, the vertical displacement of the mass spheres 1 is eliminated, so that the horizontal displacement of the slider 6 is consistent with the horizontal displacement of the mass spheres 1.

[0072] By providing a slider 6 as a force transmission carrier, the mass sphere 1 is subjected to the forces of the spring 4 and the damper 5 during rolling. By providing a removable spring 4 within the through-slot 61 at the bottom of the slider 6, the rolling damper can be tuned by replacing the spring 4 to adjust the spring stiffness according to changes in the use of the building structure, thereby achieving a more stable vibration damping effect of the rolling passive tuned mass damper.
