Description
Aeolian vibrations are one of the main sources of wear damage and fatigue failures of overhead conductors and guard wires. Stockbridge dampers are often installed along the spans of electrical transmission lines to mitigate aeolian vibrations. The dynamic response of Stockbridge dampers is typically affected by a significant degree of variability, mainly due to the manufacturing process, which determines uncertainties in the identification of the mechanical parameters of a damper model. The present paper discusses the impact of these uncertainties on the prediction of the severity of aeolian vibrations within the framework of Monte Carlo simulations.

On the assessment of aeolian vibrations of damped electrical conductors

Aeolian vibrations are one of the main sources of wear damage and fatigue failures of overhead conductors and guard wires.
