Description

Technical Field

[0001] The invention relates to the technical field of tower mast structures, and in particular to a box-type tuned particle mass damping device and a tower mast structure. Background Art

[0002] For communication tower structures, in order to adapt to the increasing types and quantities of equipment, the conventional solution to wind loads is, on the one hand, to increase the number of tower mast structures or increase the appearance and steel usage of the main structure of a single tower, and on the other hand, to set up various structural vibration reduction measures.

[0003] Structural vibration reduction control measures can be divided into active control, semi-active control, passive control and hybrid control according to different control methods. Active control requires the optimal control force to be calculated through sensor monitoring parameters, which is directly output to the controlled structure by the actuator, but its technology is complex, expensive and requires high maintenance. Semi-active control eliminates the actuator that requires external high-power power supply. According to the sensor parameter feedback, the controller only needs a small current to adjust the damping or stiffness parameters in a small range to make the damper parameters in the optimal state, but it still requires complex control algorithm calculation. Hybrid control is a new control technology that combines active and passive control developed in recent years. It can give full play to the respective advantages of passive control and active control, but the coordination and auxiliary control combination of the two is not yet mature. Passive control is a relatively mature structural vibration reduction technology currently developed. It mainly achieves the purpose of controlling the harmful vibration response of engineering structures through reasonable damper parameter design and installation position distribution.

[0004] In passive control, the tuned mass damper (TMD) is a commonly used vibration reduction device. It is an inertial mass added to the top or upper part of a tall tower, and is connected to the main structure (tall tower) with springs and dampers. The vibration frequency of the tuned mass damper is close to the frequency of the main structure. The control strategy is to use the substructure and the main structure to control the vibration mode resonance to achieve the purpose of dynamic vibration absorption, and the damping structure is used to continuously consume the energy of the main structure and the substructure to reduce the dynamic response of the main structure. TMD is usually divided into three parts: stiffness system, mass system and damping system. These parts can be combined into different types of damping devices in different ways: there are many types of stiffness systems, the mass system can be divided into two categories: solid and liquid, and the damping system can be divided into three categories: rod damper, damping box, and eddy current damper. However, the existing TMD has a narrow vibration reduction frequency band, limited energy consumption capacity, and often requires a large space to match the movement of the mass system.

[0005] Particle damper technology is a new type of damper used in the field of civil engineering vibration control in recent years. As a tuned mass and energy-consuming vibration reduction control technology, it has the advantages of small changes to the original system, small additional mass, wide vibration reduction bandwidth, and good multi-dimensional control capabilities. However, in particle dampers, the collisions between particles and between particles and cavities after the damping particles are vibrated are mostly elastic collisions, and the ability of collisions to dissipate structural energy is limited.

[0006] Therefore, there is an urgent need to provide a new tuned particle damper that can overcome the narrow TMD vibration reduction band and unstable particle damper effect, has strong energy dissipation capacity and high space utilization. Summary of the invention

[0042] Example

[0043] See also Figure 1 As shown, a box-type tuned particle mass damping device combined with collision damping is provided.

[0044] The box-type tuned particle mass damping device 100 includes a housing 110 , and a mass assembly 120 , a spring 140 , and a damping box 150 disposed in the housing 110 .

[0045] The mass block assembly 120 at least includes a particle mass block, which includes a cavity formed by a shell, the cavity is filled with a particle group, and vibration energy is consumed through friction and / or collision between the particle group itself and between the particle group and the shell.

[0046] The mass block assembly 120 is installed in the housing 110 through the pulley 130 as the lower support, so that the mass block assembly 120 can vibrate in any direction in the plane. It is worth noting that there are many ways to achieve the mass block assembly 120 to vibrate in any direction in the plane, such as setting a roller, setting a sliding protrusion at the bottom, and the friction coefficient between the sliding protrusion and the housing is very small.

[0047] The spring 130 is horizontally disposed between the mass assembly 120 and the housing 110 to provide horizontal stiffness.

[0048] One end of the damping box 150 is connected to the housing 110 , and the other end is connected to the mass block assembly 120 . When the mass block assembly 120 vibrates, the damping box 150 generates a damping force.

[0049] A collision damping bracket 160 is also provided between the mass block assembly 120 and the housing 110. The collision damping bracket 160 is installed on the vibration stroke of the mass block assembly 120 and can horizontally limit the vibration of the mass block assembly 120. In this embodiment, the collision damping bracket 160 can be directly installed on the housing 110, for example Figure 1 The bottom of the collision damping bracket 160 is fixedly mounted on the bottom plate of the housing 110; it can also be installed by a separate mounting bracket 170, such as Figure 2 The collision damping bracket 160 is fixedly mounted on the side wall of the housing 110 through the transverse mounting frame 170.

[0050] The collision damping bracket 160 may include a bracket and a viscoelastic material layer, wherein the viscoelastic material layer is installed inside the bracket and vertically arranged in the housing to receive the collision of the mass block assembly. As a part of the damping system, the collision damping bracket can provide energy dissipation for the system.

[0051] When in use, the damping device 100 is installed on the building structure, and the outer shell 110 serves as the outer skeleton and protective structure of the entire damping device 100. When the mass block assembly 120 vibrates, the particle group inside the particle mass block 121 rubs and collides with the inside of the shell, between the partitions, and between the particle groups themselves, which can consume a large amount of vibration energy; at the same time, the viscoelastic material layer on the anti-collision bracket 160 consumes energy by colliding with the mass block assembly, reducing the structural response. The anti-collision bracket 160 can significantly damp the vibration time and vibration stroke of the device itself, and dissipate motion energy. Compared with the rod-type damper, the damping box is an open layout, which solves the problems of easy leakage, difficult internal heat dissipation, and difficult to guarantee long-term performance. See Figure 3 As shown, taking the communication tower 200 as an example, by adding one or more damping devices to the communication tower 200, when the main structure of the communication tower 200 is subjected to external dynamic forces (such as wind loads), the damping device provides a force with a frequency similar or equal to that in the opposite direction of the structural movement to partially or completely offset the structural response caused by the external excitation. Optionally, the plurality of damping devices are installed on the communication tower 200 in a centrally symmetrical form through the installation platform 210.

[0052] In this embodiment, the mass block assembly 120 may further include a fixed mass block 122, and the particle mass block 121 is fixedly mounted on the upper part and / or lower part of the fixed mass block 122. The stiffness and frequency of the damping device can be adjusted by adjusting the weight and weight ratio of the particle mass block 121 and the fixed mass block 122.

[0053] See also Figure 4 As shown, the particle mass 121 includes a cavity 121b formed by a shell 121a, and the cavity 121b is filled with a particle group 121c. Vibration energy is consumed by friction and / or collision between the particle group 121c itself and between the particle group 121c and the shell 121a.

[0054] Optionally, in this embodiment, one or more partitions 121d are provided in the cavity, and the partitions 121d can separate the cavity 121b into a plurality of sub-cavities, each of which can be filled with a particle group 121c, and the vibration energy is consumed by friction and / or collision between the particle group 121c itself and between the particle group 121c and the shell 121a and the partition 121d. The volume of the particle group can account for 20% to 80% of the volume of each sub-cavity, preferably 20% to 40%.

[0055] The cavity may be a cuboid, or may be other shapes such as a cylinder, a prism, a curved surface, etc. The shape of the cavity should not be used as a limitation to the present invention.

[0056] The particle group can be composed of multiple spheres with different diameters of 1 to 60 mm. On the one hand, the collision, friction, momentum exchange and plastic deformation of the tiny particles during the collision between the spheres can consume the energy of the vibration system and achieve the effect of vibration reduction; on the other hand, the collision and friction between the spheres and the container wall (including the shell and the partition) can also consume the energy of the vibration system.

[0057] The sphere can be a mixture of one or more of a steel sphere, a lead sphere, an aluminum sphere, a ceramic sphere, a glass sphere, a plastic sphere and an alloy sphere. Optionally, in this embodiment, the sphere is a steel sphere. Of course, those skilled in the art should know that spheres are preferred vibration-damping particles, and vibration-damping particles of other shapes can also be used in the above-mentioned particle damper, which should not be used as a limitation to the invention.

[0058] The weight ratio of the particle mass 121 to the total weight of the mass assembly is

[0059] The range is 5% to 90%. The collision damping bracket 160 can be arranged at any position on the vibration stroke (or sliding stroke) of the mass block assembly.

[0060] Optionally, the weight ratio of the weight of the particle mass block 121 to the total weight of the mass block assembly is 20% to 30%, and the installation position of the collision damping bracket 160 is located at 1 / 4 to 1 / 2 of the vibration stroke of the mass block assembly 120. Within the above-mentioned weight ratio and installation position range, the vibration reduction bandwidth and energy consumption effect of the damping device 100 are more superior, while ensuring space utilization.

[0061] Combination Figure 5 Description: Assuming that the vibration stroke of the mass block assembly 120 is L, the installation position of the collision damping bracket 160 is 1 / 4 to 1 / 2 of the vibration stroke of the mass block assembly 120, that is, D = 1 / 4L to 1 / 2L.

[0062] Furthermore, the horizontal distance d between the collision damping bracket 160 and the mass block assembly 120 ranges from 20 to 100 mm.

[0063] See also Figure 6As shown, in this embodiment, considering the energy consumption effect and manufacturing cost caused by the collision, the thickness t of the viscoelastic material layer 162 is optionally in the range of 3 to 10 mm. The viscoelastic material layer 162 is installed through the bracket 161, and the bracket 161 is optionally made of rigid material to provide rigid support when receiving a collision.

[0064] See also Figure 7 As shown, in this embodiment, the spring 140 as the stiffness system can be arranged in multiple on the same horizontal plane (the multiple springs 140 can be installed around the mass block assembly 120 in a symmetrical or asymmetrical manner, and optionally, they can be installed in a symmetrical manner. The multiple springs 140 and the collision damping bracket 160 are both located between the housing 110 and the mass block assembly 120. Figure 7 In the embodiment, the collision damping bracket 160 may be configured in a ring shape corresponding to the shapes of the housing and the mass block.

[0065] It should be noted that although Figure 1 to Figure 2 The installation height of the spring in the examples is located above the collision damping bracket. It should be known to those skilled in the art that the installation height of the spring can also be located below the collision damping bracket, see Figure 8 Or in an optional embodiment, the spring can also be installed after passing through the through hole 163 on the collision damping bracket 160, see Fig. 9 shown.

[0066] In this embodiment, the damping box 150 is optionally installed on the upper part of the mass block assembly 120. For a typical damping box structure, see Fig.10 As shown: the damping box 150 includes a box body 151, and the lower part of the box body 151 is mounted on the mass block assembly. As an example and not a limitation, the bottom of the box body 151 can be mounted on the mass block assembly by fasteners such as bolts, clamps and / or adhesives.

[0067] The box 151 forms a receiving chamber 152 for containing a viscous body 154, and the viscous body 154 is a fluid or semi-fluid structure. Corresponding to the receiving chamber 152, an upper member 153 inserted into the viscous body 154 is provided. The lower end of the upper member 153 is inserted into the viscous body 154, and the upper end of the upper member 153 is connected to the housing 110. When vibrating, the upper member 153 moves in the viscous body 154 in the box 151 to generate a damping force, thereby absorbing vibration energy and reducing vibration response.

[0068] Optionally, the upper member is a vertical rod, and the vertical rod inserted in the viscous body can be set to one or more as needed. In specific implementation, the vertical rod can be made of metal material, wood material or composite material; the total length, insertion length ratio (ratio of the length located in the viscous body 154 to the total length), and cross-sectional form of the vertical rod can be flexibly arranged as needed to adjust the magnitude of the damping force.

[0069] The top of the box body may be provided with a top cover, or may be arranged in an open manner. Optionally, the top of the box body may be arranged in an open manner to solve the problem that the internal heat is not easily dissipated. Of course, considering the loss of the viscous body 154 caused by the open arrangement, a liquid level alarm may be provided to monitor the amount of the viscous body 154. When the amount of the viscous body 154 is lower than the preset scale line, a reminder message is issued through the hydraulic alarm to remind the maintenance personnel to check and replenish the viscous body.

[0070] For a damping box structure with multiple uprights, optionally, an independent compartment is provided in the box body 151 corresponding to each upright, and each upright is inserted into the compartment equipped with the viscous body 154 .

[0071] See also Fig.11 As shown, the receiving chamber 152 formed by the box 151 is divided into three compartments 156 by a partition plate 155, and a vertical rod is provided in each compartment 156. The upper end of the vertical rod is fixed by the housing 110, and the lower end of the vertical rod is inserted into the viscous body 154. Under the action of earthquake or wind load, the box swings with the mass block, and the vertical rod moves in the viscous body 154 to generate damping force, providing anti-vibration energy dissipation function for the structure.

[0072] The number of compartments 156 in the box 151 can also be adjusted as needed to adjust the magnitude of the damping force, thereby realizing the adjustable damping force function of the viscous damping box. At the same time, the movement of multiple uprights in any direction in the viscous body can generate damping force, which can realize the multi-directional viscous energy dissipation effect of the structure.

[0073] The fixed mass block 122 may be a mixture of one or more of steel, lead, concrete, grouting material and liquid.

[0074] The embodiment of the present invention further provides a tower mast structure, which includes the above-mentioned box-type tuned particle mass damping device. The structure of the box-type tuned particle mass damping device can refer to the above-mentioned embodiment, and the details are not repeated here. Since the box-type tuned particle mass damping device in the above-mentioned embodiment is adopted in this embodiment, the tower mast structure provided by the embodiment of the present invention has the same beneficial effects as the box-type tuned particle mass damping device in the above-mentioned embodiment.

[0075] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention.
