基于ANSYS Workbench的插接式管塔抗震性能分析

Anti-Seismic Analysis of Plug-In Tube Towers Based on ANSYS Workbench

通讯管塔的使用安全问题对移动通信事业至关重要。目前对于大型通信铁塔抗震性能的研究尚较少,对插接式管塔的分析则更少。本文以江苏某地所使用的移动内爬插接景观塔(金轮)为研究对象,采用SolidWorks建立该插接式管的三维模型,结合有限元分析软件ANSYSWorkbench对该单插接式管塔抗震性能进行分析。得到了该单管塔在8级地震下的方向位移云图与应力响应云图,其中塔顶最大位移434 mm,小于高耸结构水平位移的极限值;单管塔在地震激励下最大应力值为131 MPa,发生位置为单管塔底部,且最大应力值小于管塔材料的极限应力值450MPa。本次研究分析证明了该单管塔的抗震可靠性,为管塔的优化与加强提供参考依据。

The safety of communication tower is very important to mobile communication. At present, there are few researches on large communication towers, especially on plug-in tubular towers. Therefore, this paper takes the mobile internal climbing plug-in landscape tower(Golden Wheel) in Jiangsu province as the research object, uses SolidWorks to establish the three-dimensional model of the plug-in pipe, and employs the finite element analysis software ANSYS Workbench to analyze the anti-seismic performance of the single pipe tower. Through the research, the direction displacement cloud map and stress response cloud map of the single tube tower under a 8 magnitude earthquake are obtained, and the maximum displacement of the tower top is 434 mm, which is less than the limit value of the horizontal displacement of the high-rise structure, and the maximum stress value of the tube tower under the earthquake is 131 MPa, which occurs at the bottom of the tube tower, and it is less than the limit stress value of the tube tower material. This study proves the anti-seismic reliability of the plug-in tube tower, and provides reference for the optimization and strengthening of the tube tower.
