| 摘 要： | 讨论一种工程实用的线天线大吊索悬挂点几何位置的较为精确的近似解答方法。首先应用悬垂线方程式求出各悬挂点的坐标,然后根据吊索自重沿其轴线全长均匀分布的假定,应用力矩公式修正各点纵坐标。本方法适用于相等大小、相等间距集中荷载作用下的线天线大吊索,最大偏差可控制在10mm以内。在工程实用上,本方法较假定吊索自重沿弦长均匀分布的计算方法,得出的解更为精确。

| Abstract: | A new method in practical engineering is proposed to determine the approximate geometric positions of suspension points on the rope sling of wire antenna.Firstly,the coordinates of suspension points can be obtained by the suspended-cable equations,and then their ordinates are verified by the moment equations on the basis of the assumption that the dead weight of rope sling is evenly distributed along its whole axis.This method can be applied to the rope sling of wire antenna influenced by focus forces with uniform strength and distance,and its maximum error can be within 10mm.Compared with the method assuming that the dead weight of rope sling is evenly distributed along its whole chord,the result here is more accurate. |
