| 摘 要： | 提出了输电导线在覆冰和大风激励条件下舞动的双向稳定模型,该模型从输电导线垂直与扭转两种舞动机理出发,应用相关动力学方程和控制论稳定判据,对输电导线的两种舞动方式进行了分析,并分别得出了风速与导线舞动的临界关系。该稳定模型的确立可以为分析舞动原因、判别舞动模式、选择和设计防舞装置提供一定的理论依据。

| Abstract: | This article puts forward a dual-orientation galloping preventing model for electric lines under conditions of gale and being ice-coated.The model describes electric lines galloping mechanism of vertical and torsional motions.Dynamics equation and stable criterion of automatic control theory are applied to analyze two types of galloping mechanisms.The critical stable relation between lines galloping and wind speed is given.The conclusion can provide a theoretical support for analyzing the cause and deciding the mode of galloping and selecting and designing its galloping-preventing apparatus. |
