Abstract

The amplitude, frequency, and mode shape of a single galloping conductor are estimated. A finite element model of the line and supports based upon the weighted residual method is presented. The results produced by the analysis show good agreement with results obtained elsewhere. It is demonstrated that the fundamental galloping frequency can be aerodynamically dependent. Also included in the model are compliant line supports to represent the towers.
