Description

Multi-dimensional vibration-resistant communication tower and antenna assembly
Technical Field
The invention relates to the technical field of damping vibration attenuation, in particular to a multi-dimensional vibration-resistant communication tower and an antenna assembly.
Background
A communication tower (also called a signal tower) belongs to one type of signal transmitting towers, mainly functions in supporting signals, supports a signal transmitting antenna, and is mainly used for transmitting and transmitting microwave, ultrashort wave and wireless network signals. In order to ensure the normal operation of the wireless communication system, the communication antenna is usually disposed at the highest point to increase the service radius so as to achieve the desired communication effect, and the communication antenna must have a communication tower to increase the height (so the communication tower plays an important role in the communication network system).
With the development of communication technology, people have higher and higher requirements on the coverage of communication networks. The common types of communication iron towers are angle steel towers, single-pipe towers, landscape towers, guyed towers, bionic towers, beautified towers, holding poles and the like. The antenna of communication tower is usually located the communication tower upper end, and the antenna is aluminium mostly, operates at the high altitude for a long time, under strong wind interference, because lack effectual vibration canceling measure, arouse great vibration frequency and amplitude easily, then influence signal reception performance light, then lead to the antenna to warp, appear buckling and rupture phenomenon by weight.
At present, for a 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 tuned mass damping device is generally divided into three parts, namely a stiffness system, a mass system and a damping system, from the aspect of component composition, and the parts can form damping devices of different types through different combination modes.
In the prior art, a few damping devices are used for damping the vibration of the antenna on the communication tower, and the vibration damping effect is difficult to achieve. Therefore, a damping device for a communication tower antenna is needed.
