| 摘 要： | 利用梁单元模拟覆冰导线，通过动坐标迭代法和Newmark法进行静力、动力响应分析，给出了高压输电导线舞动的有限元分析方法，在此基础上编写了计算导线舞动的有限元程序，计算实例模拟了舞动的全过程，探讨了风速、攻角等对舞动的影响，其结果与文献算例能较好地符合，说明程序算法合理，对导线舞动的分析与预防有参考价值。

| Abstract: | A finite element method to analyzegalloping processes of iced transmission lines is presented. In this method,the iced powerlines are modeled by the beam element, and static and dynamic analyses are conductedby the iteration method with moving coordinates and Newmark method. A computerprogram based on the method is made to analyze the galloping of transmission lines.Anumerical example, in which the galloping process is analyzed and the effects of wind speeds and attacking angles are also discussed, is then given. The computational results agree well with the existing results, which shows that the propostdmethod in this program is reasonable and has some help to analyse and preventgalloping. |
