Abstract
Description
Technical Field
[0001] The invention relates to the field of vibration control, in particular to a vertical vibration damping device introducing a particle damper. Background Art
[0002] At present, in the field of civil engineering, structural vibration control technology plays an important role in earthquake and wind resistance. Among them, passive control technology has developed relatively maturely and is widely used in engineering practice due to its advantages such as simple concept, clear mechanism, and no need for external energy input.
[0003] Viscous dampers are excellent vibration reduction devices. Their simple structure, stable performance, and exceptional ability to absorb and dissipate earthquake impact energy on building structures have led to their widespread use in numerous projects, primarily in high-rise buildings, towering structures, stadiums, bridges, and railways. The control mechanism of a viscous damper is to dissipate a portion of the structure's vibration energy as heat through the viscous effect of the damping material, thereby alleviating the impact of external loads, reducing structural vibration, and protecting the structure's safety.
[0004] Particle damping is an added-mass passive damping technology. It involves filling a limited, enclosed space within a vibrating body or an additional cavity outside the vibrating body with a certain number of particles. Friction and collision between the particles and between the particles and the cavity walls dissipate the vibration energy input to the system, thereby providing damping for the main structure and reducing its response. Particle damping technology offers advantages such as minimal modification to the original system, wide vibration reduction bandwidth, high reliability, and strong environmental adaptability.
[0005] However, particle dampers lack vertical vibration damping capabilities. Seismic records from major earthquakes show that vertical vibrations contribute significantly to the total seismic energy. Therefore, incorporating particle dampers into vertical vibration damping, combining multiple energy dissipation methods, is of great significance for vibration control in practical engineering projects. Summary of the Invention

[0010] a central threaded rod secured to the interior centerline of the device housing; and,
[0011] The particle damping unit includes threads that are connected to a central threaded rod by rotation and lifting of the threads. When vertical vibration of the external building structure is transmitted to the particle damping unit, the threaded connection converts the vertical vibration into rotation of the particle damping unit, thereby utilizing the rotational damping effect of the particle damping unit to produce a vertical vibration damping effect on the external building structure. Furthermore, a ball bearing is provided between the threads and the threads on the central threaded rod.

[0023] Furthermore, the viscous damping unit includes a rectangular shell that is lifted and sleeved outside the central threaded rod, a viscous liquid disposed in the rectangular shell, a fan-shaped partition that is rotated in the viscous liquid, and a damping channel that penetrates the fan-shaped partition along the rotation direction;
[0024] The rotation limit of the rectangular parallelepiped shell is located within the device shell.
[0025] In some preferred embodiments, the rectangular housing and the device housing are rotationally limited by their housing shapes. For example, the device housing is a rectangular cavity, and the viscous damping housing is a rectangular housing. Furthermore, the outer circle of the horizontal cross-section of the annular column housing is an inscribed circle of the horizontal cross-section of the device housing. This means that during device operation, the annular column housing undergoes vertical motion along the central threaded rod and rotation around the central threaded rod.
[0026] Furthermore, the outer circle of the horizontal cross section of the rectangular shell is an inscribed square of the horizontal cross section of the device shell. When the device is in operation, the rectangular shell only moves vertically along the central threaded rod.
[0027] Furthermore, the viscous liquid can be added as needed, and the sector-shaped partitions can rotate relatively freely when there is no viscous liquid inside the rectangular parallelepiped shell.

The sector-shaped partition is fixedly connected to the annular cylindrical outer shell via the partition connection portion, thereby providing a transmission connection between the sector-shaped partition and the particle damping unit. The partition connection portion is an annular structure extending in the direction of rotation. Accordingly, the opening in the rectangular outer shell is an annular opening, and the sealing rubber is filled between the annular structure and the annular opening.

[0036] Furthermore, the first particle group, the second particle group and the viscous damping particle group are composed of spherical particles of different sizes, and are made of one or more of steel, glass or ceramic.
[0037] Compared with the prior art, the present invention has the following advantages and beneficial effects:
[0038] (1) The present invention has multiple energy dissipation mechanisms: Through meshing threads, the present invention converts the vertical vibration of the device into the rotation of the particle damping unit around the axis of the central threaded rod, successfully introducing the energy dissipation function of the particle damping device into vertical shock absorption, thereby enabling the particle damping unit and the viscous damping unit to achieve a combined energy dissipation and control effect, achieving good shock absorption effects for different levels of earthquake action. At the same time, the horizontal control force is converted into vertical control force, and the balls in the device can effectively reduce the tangential friction between the two relatively rotating units, resulting in only normal interaction force between the two units.
[0039] (2) The particle damping unit can automatically adjust according to the intensity of the vertical earthquake: As the vertical earthquake becomes more intense, the angular velocity of the particle damping unit will increase, so the elastic telescopic partition and the particle box in the particle damping unit will undergo radial centrifugal motion, thereby further improving the collision energy dissipation efficiency of the particles at higher linear speeds. The volume of the small chamber in the first particle device will continue to change during the movement, and the particle box in the second particle device is connected to the spring, further widening the vibration reduction frequency band of the device. After the vibration ends, each component will return to its initial position driven by the spring.
[0040] (3) Good shock absorption effect: The present invention uses the form of particles accumulated in the damping channel to replace the straight-through hole form of the traditional viscous damper. The number of capillary channels is large, and a larger damping force can be obtained at a smaller angular velocity. Moreover, the growth rate of the damping force will gradually become slower as the angular velocity increases. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0050] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0051] Example 1
[0052] This embodiment provides a vertical vibration reduction device that introduces a particle damper, such as Figure 1 As shown, it comprises: a device housing 1, a central threaded rod 4 and a particle damping unit.

[0062] In this embodiment, the elastic expansion spacer 9 in the first particle device has a structure as follows: Figure 5 As shown, it includes an arc-shaped partition body 29, a fourth spring receiving groove opened on the side of the arc-shaped partition body 29, a side sliding sleeve 30 slidingly sleeved outside the side of the arc-shaped partition body 29, and a fourth spring 28 elastically arranged between the fourth spring receiving groove and the side sliding sleeve 30; the elastic telescopic partition 9 is an arc-shaped telescopic plate, which can be extended or shortened as the device reciprocates, and the first particle group cavity is always kept as a closed space.
[0063] In this embodiment, the vertical vibration damping device further includes a viscous damping unit that is transmission-connected to the particle damping unit, such as Figure 6As shown, the viscous damping unit includes a rectangular shell 20 that is lifted and sleeved outside the central threaded rod 4, a viscous liquid 26 disposed in the rectangular shell 20, a fan-shaped partition 22 that is rotated in the viscous liquid 26, and a damping channel 23 that penetrates and is opened on the fan-shaped partition 22 along the rotation direction.
[0064] The fan-shaped partitions 22 are evenly arranged at intervals of 60° along the circumferential direction, and the viscous liquid 26 can be added as needed. When there is no viscous liquid 26 inside the rectangular shell 20, the fan-shaped partitions 22 can rotate relatively freely.
[0065] The damping channel 23 is filled with a group of viscous damping particles 24. The two end plates of the damping channel 23 are provided with small holes with a diameter smaller than that of the particles to prevent the particles from leaking out or becoming blocked.
[0066] An opening is provided on the rectangular shell 20 for the fan-shaped partition 22 to pass through, and a sealing rubber 25 is filled between the opening and the fan-shaped partition 22 to prevent leakage of the viscous liquid 26. The viscous damping unit is transmission-connected to the particle damping unit through the fan-shaped partition 22; at the same time, an I-shaped second directional connecting member 21 is also provided between the circular column shell 8 and the rectangular shell 20, and the two ends of the second directional connecting member 21 are respectively slidably embedded in the annular grooves on the circular column shell 8 and the rectangular shell 20, so that the circular column shell 8 and the rectangular shell 20 are connected by the second directional connecting member 21 to realize the lifting and lowering transmission connection.
[0067] In this embodiment, the structure of the second directional connector 21 is as follows: Figure 7 As shown, the second directional connecting member 21 includes an I-shaped ring 27 , and balls 5 are evenly arranged at the upper and lower ends of the I-shaped ring 27 along the circumferential direction.
[0068] In this embodiment, the outer circle of the horizontal cross-section of the circular column housing 8 is the inscribed circle of the horizontal cross-section of the device housing 1, and the outer circle of the horizontal cross-section of the rectangular housing 20 is the inscribed square of the horizontal cross-section of the device housing 1. There is no friction between the contact surfaces, that is, when the device is operating, the circular column housing 8 will move vertically along the central threaded rod 4 and rotate around the central threaded rod 4, while the rectangular housing 20 will only move vertically along the central threaded rod 4.
[0069] In this embodiment, the first particle group 14 , the second particle group 19 and the viscous damping particle group 24 are composed of spherical particles of different sizes, and are made of one or more of steel, glass or ceramic.
[0070] In this embodiment, the device housing 1, the annular column housing 8, the second particle box 18 and the rectangular parallelepiped housing 20 are welded together by 5-10 mm steel plates.
[0071] The shock absorbing device described in this embodiment is mainly used for earthquake shock absorption.
[0072] When the shock absorption device provided in this embodiment is in use, when a vertical earthquake vibration is input, the entire device begins to vibrate vertically, driving the particle damping unit and the viscous damping unit to generate vertical reciprocating motion. Due to the meshing of the internal threads 6 with ball bearings 5 and the central threaded rod 4, the particle damping unit rotates about the axis of the central threaded rod 4. Consequently, the first particle group 14 consumes energy input to the system through friction and collision between particles and between particles and the cavity wall. Simultaneously, the fan-shaped baffle 22 within the viscous damping unit, welded and fixed to the annular cylindrical housing 8 of the particle damping unit, also rotates about the axis of the central threaded rod 4, causing viscous liquid 26 to pass through the damping channel 23 filled with the viscous damping particle group 24, consuming energy input to the system. Furthermore, the meshing threads convert the horizontal control force generated by the particle damping unit and the viscous damping unit during operation into vertical control force. Furthermore, the particle damping unit automatically adjusts to the intensity of vertical seismic motion. As the vertical seismic motion increases, the particle damping unit's angular velocity increases. Consequently, the elastically retractable baffles 9 and the second particle housing 18 within the particle damping unit undergo radial centrifugal motion, further improving the particle collision energy dissipation efficiency at higher linear velocities. The volume of the small chamber within the first particle device continuously changes during motion, and the second particle housing 18 within the second particle device is connected to an external spring, further widening the device's vibration damping frequency band. After the seismic motion subsides, the components, driven by the springs, return to their initial positions.
[0073] The above description of the embodiments is intended to facilitate understanding and use of the invention by those skilled in the art. It will be apparent that those skilled in the art can readily make various modifications to these embodiments and apply the general principles described herein to other embodiments without requiring inventive effort. Therefore, the present invention is not limited to the above-described embodiments.
