Description

Technical Field

[0001] This invention relates to the field of building structure vibration control technology, and in particular to a tuned mass damper with inertial capacitance. Background Technology

[0002] High-rise buildings have a large slenderness ratio and low stiffness and damping, thus exacerbating harmful vibrations caused by external forces such as earthquakes and wind. Traditional methods for wind and earthquake resistance in engineering structures, such as strengthening the structure's strength, stiffness, and damping or altering mass distribution, increase construction costs and may not achieve the desired results. To address this issue, vibration control technology for civil engineering structures has emerged and gradually become widespread, drawing inspiration from vibration reduction methods used in aerospace and mechanical engineering. In the field of vibration control, tuned mass dampers (TMDs) are a relatively mature control method and are widely used in wind load and seismic response control of various high-rise structures.

[0003] TMD systems absorb structural vibration energy through the resonance effect of inertial mass and the main vibration modes of the structure. To ensure control effectiveness, implementing TMD technology often requires a large inertial mass, places high demands on the space required for the structure, is inconvenient to install, and is costly. It may also increase the seismic response of the main structure. Summary of the Invention

The first spring assembly and the second spring assembly are detachably connected to the inner surfaces of the first end and the second end of the mounting bracket, respectively. The elastic force direction of the first spring assembly and the second spring assembly is parallel to the sliding direction of the mass block.

[0013] Optionally, the mounting bracket includes a base, a first partition, and a second partition;

[0031] The worm gear is located directly below the gear, and the weight of the mass block is mainly borne by the worm gear.

At the same time, it can also prevent the guide rail from bending under force and reduce the difficulty of maintenance of the guide rail.

[0032] The reciprocating motion of the mass block drives the first and second flywheels to rotate, providing apparent mass for the control system and significantly reducing the inertial mass requirement. The use of worm gear and gear transmission effectively improves the reliability and stability of the tuned mass damper, resulting in good control performance.

[0041] To better explain and facilitate understanding of the present invention, a detailed description of the invention is provided below with reference to the accompanying drawings and specific embodiments. In this document, directional terms such as "upper," "lower," etc., are used interchangeably with respect to... Figure 1 The orientation is used as a reference.

[0042] While exemplary embodiments of the invention are shown in the accompanying drawings, it should be understood that the invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the invention can be understood more clearly and thoroughly, and that the scope of the invention can be fully conveyed to those skilled in the art.

[0043] like Figures 1-5As shown, this invention provides a tuned mass damper with inertial capacitance, comprising a mounting frame, a mass block 1, a damping device, a gear 5, a worm gear 6, a first clutch device 8, a second clutch device, a first flywheel 7, a second flywheel, and an elastic device. The mass block 1 is linearly slidably mounted on the mounting frame. In a preferred embodiment, guide rails 2 are arranged in pairs on the mounting frame, and the mass block 1 is slidably connected to the guide rails. When a high-rise building sways, the mass block 1 reciprocates along the guide rails. The damping device and the elastic device are both connected between the mounting frame and the mass block 1, together forming the tuned mass damper. The gear 5 is fixedly mounted on the mass block 1, and the worm gear 6 is rotatably mounted on the mounting frame, with the central axis of the worm gear 6 parallel to the sliding direction of the mass block 1. When the mass block 1 reciprocates, it drives the gear 5 to move, which in turn drives the worm gear 6 to rotate back and forth. The worm gear 6 is located directly below the gear. The weight of the mass block 1 is mainly borne by the worm gear 6. The guide rail 2 only plays a guiding role and assists the movement of the mass block 1. It effectively avoids wear on the guide rail 2 and reduces noise caused by improper surface treatment of the guide rail 2. At the same time, it can also prevent the guide rail 2 from bending under force and reduce the difficulty of maintenance of the guide rail 2.

[0044] The first flywheel 7 is connected to the first end of the worm 6 via the first clutch device 8, and the second flywheel is connected to the second end of the worm 6 via the second clutch device. Both ends are fixed to the gear 5 below the mass block 1. The worm 6 meshing with the gear 5, the two flywheels connected to the two ends of the worm 6, and the two clutch devices constitute the inertia container. First, the vibration energy of the upper structure is transferred to the mass block 1. Then, the reciprocating motion of the mass block 1 drives the two flywheels to rotate, thereby transferring most of the vibration energy in the mass block 1 to the flywheels and dissipating it by the inherent damping of the flywheels. When the mass block 1 slides in the first direction, the mass block 1 drives the first flywheel 7 to rotate in one direction via the first clutch device 8. When the mass block 1 moves in the second direction, the mass block 1 drives the second flywheel to rotate in one direction via the second clutch device, preventing the vibration energy stored in the first flywheel 7 and the second flywheel from being not dissipated in time and being transmitted back to the worm 6.

[0045] Specifically, when mass block 1 moves towards the second flywheel, it drives worm gear 6 to rotate counterclockwise, which in turn drives the first flywheel 7 to rotate counterclockwise via worm gear 6 and the first clutch device 8. At this time, the second clutch device cannot drive the second flywheel to rotate. When mass block 1 moves towards the first flywheel 7, it drives worm gear 6 to rotate clockwise, which in turn drives the second flywheel to rotate clockwise via worm gear 6 and the second clutch device. At this time, the first clutch device 8 cannot drive the first flywheel 7 to rotate, and the first flywheel 7 continues to rotate due to inertia. The first and second flywheels are preferably made of steel, and their moment of inertia depends on their physical mass. The apparent mass generated by the inertia container depends on the moment of inertia and rotational speed of the two flywheels. Excessive moment of inertia will prevent the flywheels from being driven. Therefore, the parameters of the inertia container must be selected appropriately according to the vibration control objectives of the main structure.

[0046] The reciprocating motion of mass block 1 drives the first flywheel 7 and the second flywheel to rotate, providing apparent mass for the control system and significantly reducing the inertial mass requirement; the use of worm gear 6 and gear 5 transmission effectively improves the reliability and stability of the tuned mass damper and has a good control effect; the tuned mass damper occupies little space and can adapt to the vibration control requirements of various high-rise buildings by adjusting the damping parameters.

[0047] See Figure 1 and Figure 2 The damping device includes a first viscous damper 4 and a second viscous damper. The first viscous damper 4, the mass block 1, and the second viscous damper are detachably connected in sequence. The first viscous damper 4 and the second viscous damper are detachably connected to the inner surfaces of the first and second ends of the mounting frame, respectively. The extension and contraction directions of the first viscous damper 4 and the second viscous damper are parallel to the sliding direction of the mass block 1. The elastic device includes a first spring assembly and a second spring assembly 3. The first spring assembly, the mass block 1, and the second spring assembly 3 are detachably connected in sequence. The first spring assembly and the second spring assembly 3 are detachably connected to the inner surfaces of the first and second ends of the mounting frame, respectively. The elastic force direction of the first spring assembly and the second spring assembly 3 is parallel to the sliding direction of the mass block 1. In one embodiment, the first spring assembly and the second spring assembly 3 each include two parallel helical steel springs, using a total of four detachable helical steel springs and two viscous dampers to provide stiffness and damping for the device.

[0048] See Figure 1The mounting bracket includes a base 12, a first partition plate, and a second partition plate 10. Both the first and second partition plates 10 are vertically mounted on the base 12, facing each other and located at the left and right ends of the base 12, respectively. The two ends of a worm gear 6 are rotatably connected to the first and second partition plates 10, respectively, and pass through both partition plates 10. A first flywheel 7 and a second flywheel are respectively arranged on the outer sides of the first and second partition plates 10. The first flywheel 7 is connected to the end of the worm gear 6 extending from the first partition plate via a first clutch device 8, and the second flywheel is connected to the end of the worm gear 6 extending from the second partition plate 10 via a second clutch device. A first viscous damper 4 and a first spring assembly are both connected to the first partition plate, and a second viscous damper and a second spring assembly 3 are both connected to the second partition plate 10.

[0049] When mass block 1 moves in the first direction, the first clutch device 8 is engaged and the second clutch device is disengaged. When mass block 1 moves in the second direction, the first clutch device 8 is disengaged and the second clutch device is engaged, thus preventing the two flywheels from constantly stopping and reversing during operation, which would affect energy efficiency.

[0050] Furthermore, a turntable 9 is fixedly mounted on both the first and second ends of the worm 6, and the first flywheel 7 and the second flywheel are rotatably connected to the turntable 9 on the first and second ends of the worm 6, respectively. A first clutch device 8 is mounted on the turntable 9 located at the first end of the worm 6, and a second clutch device is mounted on the turntable 9 located at the second end of the worm 6. Further, see... Figure 5 Both the first clutch device 8 and the second clutch device include a locking block 81 and an elastic element 83. A radially arranged groove 82 is provided on the turntable 9, and the locking block 81 is slidably connected to the groove 82. When the turntable 9 rotates with the worm gear 6, it drives the locking block 81 to rotate synchronously. The locking block 81 moves radially along the turntable 9. The elastic element 83 is preferably a steel spring, connected between the locking block 81 and the worm gear 6. Both the first flywheel 7 and the second flywheel have annular toothed grooves. The locking block 81 of the first clutch device 8 can be inserted into the toothed groove on the first flywheel 7 to drive the toothed groove on the first flywheel 7 to rotate, and the locking block 81 of the second clutch device can be inserted into the toothed groove on the second flywheel to drive the toothed groove on the second flywheel to rotate. Taking the first flywheel 7 as an example, only when the worm 6 rotates in a single direction and the rotational speed of the worm 6 is greater than that of the first flywheel 7 can the locking block 81 tightly mesh with the tooth groove of the inner ring of the first flywheel 7 and drive the first flywheel 7 to rotate, preventing the vibration energy stored in the first flywheel 7 from being dissipated in time and being transmitted back to the worm 6; when the worm 6 rotates in reverse, or when the rotational speed of the worm 6 is less than that of the first flywheel 7, the locking block 81 cannot mesh with the tooth groove, and the first flywheel 7 is isolated from the system and rotates to dissipate energy alone; the rotation of the second flywheel is similar.

[0051] See Figure 1The mass block 1 includes a mounting base and at least one counterweight plate. The mounting base is linearly slidably mounted on a mounting frame. Both a damping device and an elastic device are connected to the mounting base. The first flywheel 7 and the second flywheel are both connected to the mounting base via a connecting device. The counterweight plate is mounted on the mounting base, or multiple counterweight plates are stacked sequentially on the mounting base. Specifically, the mass of the mass block 1 is mainly composed of the stacked counterweight plates. Holes are drilled at the four corners of each layer of counterweight plates. Four connecting rods passing through these holes connect each layer of counterweight plates in series, and bolts are used to secure the tops of the connecting rods. Users can freely adjust the number of counterweight plates according to different application scenarios, improving application flexibility.

[0052] Preferably, the worm 6 is rotatably connected to the mounting bracket via a bearing 11. Specifically, the first and second partition plates 10 have holes with a diameter slightly larger than the root circle diameter of the worm 6. Both ends of the worm 6 pass through the holes, and rolling bearings 11 are provided at the connection to ensure the smooth rotation of the worm 6.

[0053] like Figure 3 and Figure 4 As shown, gear 5 is a helical gear. Both ends of the helical gear are welded to the mass block 1 to form a whole and participate in the reciprocating motion. During this process, the helical gear does not rotate. The axis of the worm 6 is perpendicular to the axis of the helical gear but does not intersect. The helical teeth of the worm 6 mesh with the teeth of the helical gear and can rotate in both directions under the drive of the helical gear. Specifically, the parameters such as the addendum, dedendum, and pitch circle radius of the worm 6, as well as the parameters such as the helix angle, pressure angle, and module of the helical gear, are all calculated and selected according to actual needs. The introduced worm gear 6 and helical gear inertial-compressive configuration leverage the advantages of worm gear 6's stable, smooth, low-noise transmission and simple, easy-to-implement structure. The inertial mass requirement of the tuned mass inertial-compressive damping system is significantly reduced, the device is simple and compact in construction, and the space required for implementing the control system is small. It can be distributed in multiple locations on high-rise structures to control higher-order vibration modes excited by seismic forces. The spring, damper, and flywheel are all detachable and replaceable components to adjust the frequency, damping, and apparent mass of the tuned mass inertial-compressive damping system. The overrunning clutch device, which works in conjunction with the flywheel, ensures that the flywheel always rotates in one direction and that the vibration energy absorbed by the flywheel is not transmitted back to the worm gear 6, effectively improving the energy efficiency of the device.

[0054] This invention introduces a worm gear 6 and gear transmission as a new inertial container implementation method, improving the stability and smoothness of the tuned mass inertial capacitive damping system and enhancing overall energy efficiency. For wind-induced vibrations or seismic events affecting high-rise structures, the operating frequency of the tuned mass inertial capacitive damping system is tuned to the fundamental frequency of the main structure. Based on the resonance principle, the vibration energy of the main structure is transferred to the mass block 1, causing it to reciprocate. Energy is dissipated using a viscous damper, reducing the stroke of the mass block 1. Simultaneously, the mass block 1 drives the worm gear 6 and the flywheels at both ends to rotate via gears, providing an apparent mass tens or even hundreds of times greater than the physical mass of the flywheels themselves. This reduces the inertial mass requirement of the tuned mass inertial capacitive damping system, achieving the goals of lightweighting and miniaturization.
