摘要: 利用ABAQUS软件建立覆冰四分裂导线线路的有限元模型,模拟不同线路在不同风速下的舞动过程.基于线路动力特性和舞动数值模拟结果,分析不同档距和档数连续档线路在不同风速下的舞动模式、频率特性和振动幅值,并与孤立档线路的舞动特征进行比较.结果表明,连续档线路两边档的舞动模式和频率特性可能与中间各档不同,连续档线路的舞动特征与孤立档差别明显,在进行舞动防治技术研究时应考虑这些差异.Abstract: Finite element models of iced quad bundle conductor lines were set up and galloping processes of these lines were numerically simulated by means of ABAQUS software. Based on the analysis of the dynamic characteristics of the conductor lines and the galloping responses, the galloping vibration modes, frequencies and amplitudes of the continuous multi-span lines with different span lengths and span numbers were investigated and compared with those of the single-span dead-end lines. It is shown that the galloping modes and frequencies of the two end-spans of the multi-span lines are different from those of the intermediate spans, and the galloping characteristics of the multi-span lines are different from those of the single-span lines, which have to be taken into account in the development of anti-galloping technology.
