采用ABAQUS有限元软件建立真型试验线路塔线耦合体系有限元模型，对安装人工D形覆冰模型的六分裂导线的舞动进行数值模拟，得到导线舞动过程中的位移响应、舞动轨迹、舞动形态和频率以及导线的张力变化等。数值模拟与现场实测结果较吻合，验证了数值模型和舞动模拟方法的正确性。所建立的数值模型可进一步用于舞动特征及防舞装置的评估及优化研究，为试验方案的确定提供依据。

The tower-line coupled finite element model of a transmission test line was set up by means of ABAQUS software.Galloping of six-bundle conductors with D-shaped ice model in the line was numerically simulated,the dynamic displacement responses,galloping orbits,galloping modes and frequencies were obtained.The numerical simulation results were consistent with those measured on the transmission test line,they verifies the correctness of the numerical model and the simulation method.The established finite element model and the numerical method could be employed to investigate galloping behaviors and assess anti-galloping techniques.
