Based on the differences aerodynamic characteristics between each sub-conductor of iced bundled conductors, a two-node cable element with three translational and one torsional degrees of freedom at each node is utilized to imitate the bundled conductor and the two-node space beam elements are used to simulated the spacers. Established nonlinear finite element equations of bundled conductors based on the principle of virtual work and solved these equations using Newmark-β method. Numerical example was employed to demonstrate the reliable and efficient of the presented method and program.
