Summary: | The invention relates to a conductor galloping resistant method of the iron towers of overhead power transmission lines. The method comprises the following steps: building a iron tower model, setting conductor galloping parameters, building a coupling system model of iron towers and conductors, adding iron tower nodal loads, setting tower foot nodal constraints, defining a load curve; setting time parameters, using a core computing module for computing and solving; using a post-processing module to directly display the galloping animation of conductors and iron towers, and directly computing and outputting an internal force-time history curve of iron tower units; and checking the bearing capacity of iron tower units according to the computed and output internal force-time history curve ofiron tower units, and judging whether iron tower units are needed to reinforce. The conductor galloping resistant method considers the coupling effect of iron towers and conductors, has higher accuracy in the research of the |
