Aeolian vibration of a single conductor with a Stockbridge damper

Abstract

The planar vibrational response of a single conductor with an attached Stockbridge damper is investigated. The mathematical model accounts for the two-way coupling between the conductor and the damper, the flexural rigidity of both the damper and the conductor, and the mass of the two counterweights of the damper. Hence, the dynamic behaviors of the damper and conductor are simultaneously assessed. Both free and forced vibration analyses are implemented via the use of a finite element code developed in MATLAB. The results of the force vibration analyses show that the effectiveness of Stockbridge dampers depends on their location, mass, and excitation frequency.
