| 摘 要： | 在对悬索式天线面的结构分析与计算中,若将悬挂线简单地视为直线,则难以保证天线施工后的成型良好。为此,本文提出一种工程实用的悬索式多模多馈天线的较为精确的结构分析与计算方法。首先根据各悬挂点高度保持不变的特点,应用悬垂线方程式计算各悬挂点半径,然后应用力矩公式修正以上计算结果,确定振子线各节段的长度。本方法适用于不等大小、不等间距集中荷载作用下的线天线悬索,可以保证天线施工后的成型良好,与传统的几何计算方法相比,本方法得出的解更为精确。

| Abstract: | In practical engineering,it is hard to ensure fine shape to the suspension structure antenna with the structural analysis and calculation method,which considers the suspended cable as straight line simply.In this paper,a new method is proposed to analyze and calculate the suspension structure of multimode multi-feed antenna.Firstly,the radii of suspension points can be obtained by the suspended-cable equations on the basis of the character that the heights of suspension points are of constancy,and their radii are verified by the moment equations.Then the lengths of antenna wire segments are determined.This method can be applied to the wire antenna ropes influenced by focus forces with different strength and distance,and ensures fine shape to the antenna.Compared with the result of conventional geometric calculation method,the result here is more accurate. |
