摘　　要：讨论一种工程实用的扇锥天线较为精确的结构分析与计算方法。在二维平面内应用悬垂线方程式计算边吊索上各悬挂点的坐标,应用力矩公式修正以上计算结果,确定各振子线的长度。方法适用于不等大小、不等间距、不同方向集中荷载作用下的线天线悬吊索,可以保证天线施工后的成型良好。在工程实用上,与传统的几何方法计算的结果相比,本方法得出的解更为精确。In practical engineering, a new method is proposed for structural analysis and calculation on fanshaped antenna. Firstly, the coordinates of suspension points on the side rope sling can be obtained in two dimensional plane by the suspended-cable equations, and their ordinates are corrected by the moment equations, then the lengths of antenna wire segments are determined. This method applies to the wire antenna＇s rope slings influenced by focus forces with different strength, distance and direction, and it ensures fine shape to the antenna. Compared with the calculating result of conventional geometric method in practical engineering, the result here is more accurate.
