| 摘 要： | 覆冰导线由于风载而造成的舞动，严重地威胁着输电线路的安全运行。本文建立了覆冰导线的运动方程，求出其数值解，拟合出空气动力系数曲线，得到比较完全的覆冰导线运动稳定性判据，讨论了失谐摆抑制舞动的可能性，并用Ｃ语言在ＰＣ机上开发出一套导线舞动的仿真系统，对我国跨越汉水的中山口大跨越输电线路作了具体的分析与计算。

| Abstract: | The galloping of iced conductor caused by wind load severely imperils the safe operation of the high voltage transmission line.In this paper,the equations of motion of the iced conductor are established and their numerical solutions are obtained, the experimental curves of aerodynamic coefficients are simulated and the criteria of stability of motion of the iced conductor are also gained.The possibility of using mismatching pendulum to prevent the galloping is studied.A dynamic simulating system programmed by C language is presented.The analyzing and calculating of the large span transmission lines across the Hanshui river'sZhongshankou are proceeded. |
