摘　　要：使用ABAQUS/CAE建立连续五档导线-绝缘子塔线体系有限元模型,采用驻波法模拟导线舞动激励,通过在模型右侧施加驻波,左侧不施加驻波,模拟舞动分界点环境。通过简化导线张力比计算公式,分析舞动分界点两侧导线应力情况。通过某时刻杆塔Mises应力分布图,分析舞动分界点杆塔受力情况。结合分析结论和现场实际情况,得出针对舞动分界点杆塔的过渡防舞措施。ABAQUS/CAE is used to establish the limited meta-model of the tower-wire system with five sections of wire-insulator. Stationary wave method is employed to simulate the wire waving. In order to simulate the circumstances of demarcation point of the wire waving range, the standing wave is applied to the right of the model and none to the left. The paper also analyzes the stress of the wire on both sides of the galloping demarcation point by simplifying the calculation formula of the tension ratio of the wire. Finally the paper combines the analysis conclusion and the actual situation at the scene to obtain the antigalloping approaches for the wire galloping demarcation point.
