| 摘 要： | 利用三维有限元方法，分析了风速、攻角、导线分裂、磁场力和防舞装置等各种因素对导线舞动的影响．结果表明：风速、攻角和导线分裂等对导线舞动的影响很大；磁场力的影响很小．为减轻和防止导线舞动，在导线距离杆塔1／3和2／3处施加压重，可以获得明显的防舞效果．

| Abstract: | The effects of wind speed, attack angle, bundle, magnetic force and weight hammer on galloping were analyzed by utilizing the 3D finite element method. The results showed that the effects of wind speed, attack angle and bundle were great, but the effect of magnetic force was very small. The results also showed that to fix weight hammers at the 1/3 and 2/3 span of the line is effective for guarding against galloping. |
