Description
Technical Field
The invention relates to the technical field of tower mast structures, in particular to a box type tuning particle mass damping device and a tower mast structure.
Background
For the communication tower structure, in order to adapt to more and more equipment types and quantities, the conventional solution of wind load is to increase the number of tower mast structures or increase the appearance of a single tower main body structure and the steel consumption on one hand, and to set various structural vibration reduction measures on the other hand.
The structural vibration damping control measures are different according to control modes and can be divided into active control, semi-active control, passive control and hybrid control. The optimal control force needs to be calculated through monitoring parameters of a sensor in the active control mode, and is directly output to a controlled structure through an actuator, but the active control method is complex in technology, high in manufacturing cost and high in maintenance requirement. The semi-active control eliminates an actuator which needs external high-power supply, and only needs a controller with small current to adjust damping or rigidity parameters within a small range according to sensor parameter feedback, so that the damper parameters are in an optimal state, but the damper parameters still need complicated control algorithm calculation. Hybrid control is a new control technology developed in recent years and combining active control with passive control, and can exert respective advantages of passive control and active control, but the combination mode of cooperation and auxiliary control of the two is not mature. The passive control is a structure vibration reduction technology which is developed more mature at present, and achieves the purpose of controlling the harmful vibration response of the engineering structure mainly through reasonable damper parameter design and installation position distribution.
In passive control, a Tuned Mass Damper (TMD) is a common damping device, and is formed by adding an inertial Mass to a top or upper portion of a tower, and connecting the Mass to a main structure (tower) with a spring and a Damper. The vibration frequency of the tuned mass damper is close to the frequency of the main structure, the control strategy is to apply the vibration mode resonance of the sub-structure and the main structure to achieve the purpose of dynamic vibration absorption, and the application of the damping structure continuously consumes the energy of the main structure and the sub-structure to reduce the dynamic response of the main structure. The TMD is generally divided into three parts, namely a rigidity system, a mass system and a damping system from the component composition, and the three parts can form damping devices of different types through different combination modes, wherein the rigidity system has more types, the mass system can be divided into two types of solid and liquid, and the damping system can be divided into three types of rod type dampers, damping boxes and eddy current dampers. However, the damping frequency band of existing TMDs is narrow, the energy dissipation capability is limited, and it often requires a large space to match the motion of the mass system.
The particle damper technology is a novel damper applied to the field of civil engineering vibration control in recent years, and has the advantages of small change to an original system, small additional mass, wide vibration damping frequency band, good multi-dimensional control capability and the like as a tuned mass and energy consumption vibration damping control technology. However, in the particle damper, the collisions between particles and cavities after the damping particles start to vibrate are mostly elastic collisions, and the energy dissipation capability of the collision structure is limited.
Therefore, it is desirable to provide a novel tuned particle damper which can overcome the defects of too narrow damping frequency band of TMD, unstable effect of the particle damper, strong energy consumption capability and high space utilization rate.

Examples
Referring to fig. 1, a box-type tuned particle mass damping device incorporating impact damping is provided.

The mass assembly 120 is mounted in the housing 110 as a lower support through pulleys 130 so that the mass assembly 120 can vibrate in any direction in a plane. It should be noted that there are many ways to achieve the vibration of the mass assembly 120 in any direction in a plane, such as providing rollers, providing sliding protrusions at the bottom, providing a very small coefficient of friction between the sliding protrusions and the housing, etc.
The spring 130 is horizontally disposed between the mass assembly 120 and the housing 110 for providing horizontal stiffness.
The damping case 150 has one end connected to the housing 110 and the other end connected to the mass assembly 120, and the damping case 150 generates a damping force when the mass assembly 120 vibrates.
A crash damping mount 160 is also provided between the mass assembly 120 and the housing 110. The impact damping support 160 is installed on a vibration stroke of the mass assembly 120 and can horizontally limit vibration of the mass assembly 120. In this embodiment, the impact damping bracket 160 may be directly mounted on the housing 110, for example, the bottom of the impact damping bracket 160 is fixedly mounted on the bottom plate of the housing 110 in fig. 1; the mounting may also be performed by a separate mounting bracket 170, such as the impact damping bracket 160 fixedly mounted to the side wall of the outer shell 110 by a lateral mounting bracket 170 in fig. 2.
In use, the damping device 100 is installed on a building structure, and the housing 110 serves as a peripheral skeleton and a protective structure of the entire damping device 100. When the mass block assembly 120 vibrates, the particle groups in the particle mass block 121 rub and collide with the inside of the shell, the partition plates and the particle groups, so that a large amount of vibration energy can be consumed; meanwhile, the energy consumed by the collision between the viscoelastic material layer on the anti-collision support 160 and the mass block assembly is reduced, the structural response is reduced, and the anti-collision support 160 can remarkably reduce the vibration time and the vibration stroke of the damping device and dissipate the motion energy. Compared with a rod-type damper, the damping box is arranged in an open manner, so that the problems of easy leakage, difficult dissipation of internal heat and difficult guarantee of long-term performance are solved, as shown in fig. 3, for example, by adding one or more damping devices to the communication tower 200, when a main structure of the communication tower 200 is subjected to external dynamic force (such as wind load), the damping devices provide a force with a frequency close to or equal to and opposite to the moving direction of the structure, so as to partially or completely counteract structural response caused by external excitation.

The volume of the population of particles may be from 20% to 80%, preferably from 20% to 40%, of the volume of the chamber of each subchamber.
The cavity may be a rectangular parallelepiped, or may be in other shapes such as a cylinder, a prism, a curved surface, etc., and the shape of the cavity should not be construed as limiting the present invention.
The particle group can be optionally composed of a plurality of spheres with different diameters of 1-60 mm. On one hand, collision, friction and momentum exchange among the spheres and plastic deformation of the tiny particles during mutual collision can consume the energy of a vibration system, so that the effect of vibration reduction is realized; on the other hand, the collision, friction, and the interaction between the sphere and the vessel wall (including the housing and the baffle) can also dissipate the energy of the vibration system.
The ball body can be formed by mixing one or more of a steel ball body, a lead ball body, an aluminum ball body, a ceramic ball body, a glass ball body, a plastic ball body and an alloy ball body. Optionally, in this embodiment, the ball is a steel ball. Of course, those skilled in the art will recognize spheres as the preferred vibration damping particles, and other shapes of vibration damping particles may be used in the above-described particle damper, which should not be construed as limiting the invention.
