Abstract The variation laws of lift, drag and torque coefficients of a quad-bundle conductor with typical crescent icing were obtained with wind tunnel tests. A numerical simulation method for iced conductor galloping considering effects of eccentric icing was proposed based on the FE software ABAQUS, and the correctness of the method was verified with examples. The user self-defined subroutine UEL in ABAQUS was used to program an aerodynamic load element, and realize the numerical simulation method for iced conductor galloping considering effects of eccentric icing. The proposed method and the traditional numerical simulation one were used to contrastively analyze galloping characteristics of a quad-bundle conductor with typical crescent icing. The results showed that the proposed method can be used to accurately describe the torsional feature of the iced conductor motion; after considering effects of eccentric icing, displacement and torsional angle amplitudes of the iced quad-bundle conductor obviously increase and its vibration mode is more complex; it is necessary to consider effects of eccentric icing when studying galloping of iced conductor.
