摘要

复杂的天气环境对垂直笼形天线的结构变形和电性能有重要影响。针对垂直笼形天线在多风向风荷载作用下的非线性响应,提出了一种机电耦合分析方法。采用非线性有限元法对垂直笼形天线在多风向风荷载作用下的结构进行了分析。基于变形垂直笼形天线的几何模型,采用矩量法对天线的电性能进行了分析。计算了垂直笼形天线在多风向风荷载作用下的输入阻抗和驻波比。

Mechanical-electrical Coupling Analysis of Vertical Cage Antenna Electrical Performance under Multi-wind Direction Wind Loads
The complex weather environment has an important influence on the structural deformation and electrical performance of the vertical cage antenna. In this paper, a mechanical-electrical coupling analysis method is proposed to analyze the nonlinear response of the vertical cage antenna under multi-wind direction wind loads. The nonlinear finite element method is used to analyze the structure of the vertical cage antenna under the multi-wind direction wind loads. Based on the geometric model of the deformed vertical cage antenna, the electrical performance of the antenna is analyzed by the method of moments. The import impedance and the VSWR of the vertical cage antenna under multi-wind direction wind loads are calculated.
