一体化通信塔风振响应分析

The Wind Vibration Response Analysis of the Integrated Communication Tower

针对传统基站建设需要进行地勘和土建基础施工的问题,设计一种新型的一体化通信基站,其塔体和机房连为一体,塔体自身、塔体和机房之间可以通过叠及展开实现运输及运行两种方式。采用线性滤波法的ARMA模型,借助MATLAB软件对通信塔的脉动风速时程进行模拟,模拟得到的脉动风速时程功率谱与Von Karman目标谱在峰值以及平稳性方面吻合良好,并在此基础上进行风荷载时程模拟。在ANSYS中实施加载,得到通信塔在脉动风场中的动力响应,结果表明一体化通信塔的结构是可行的。

Considering geological exploration and civil foundation construction of the traditional communication station,a new type of integrated communication tower is designed.The tower body and engine room of new type of integrated communication station is integrated basing on the analysis of the demand for functional design,the tower body itself,the tower body and engine room can be folded and unfolded itself with transportation and operation in two ways.By use of linear filter ARMA model and MATLAB,the fluctuating wind velocity time history is simulated,and the peak value and stationeries of the simulated result and the target spectrum Von Karman are in good agreement.The wind load is simulated on this basis.The wind load is imported to ANSYS,and the fluctuating wind vibration response of the communication tower is carried out.The result shows that the structure of the integrated communication tower is feasible.
