The invention discloses an iced conductor galloping ANSYS numerical simulation method based on a beam element, comprising the following steps: establishing a conductor static model; the static model of conductor being extended to the transmission line, and the static model of transmission line being obtained; establishing a split spacer bar model; solving the lifting force, damping force and torque of any conductor; loading the lifting force, damping force and torque wire model to obtain the wire force model; solving a transformation matrix to obtain the motion displacement value and the velocity value of all nodes of the local coordinate unit of the traverse; transforming the overall coordinate system of the traverse displacement into a local element coordinate system; the nodal forces attwo nodes of each local element of a single wire being solved, and the overall force of the wire being obtained by using the transformation matrix. The ice galloping model of conductor is obtained bytransforming the whole force of conductor into the whole coordinate system. Then the ice galloping model of transmission line is obtained. The utility model has the advantages that the anti-gallopingeffect of the split spacer rod is tested by changing the installation mode of the split spacer rod so as to improve the reliability of the transmission line.
