A new method is presented for determining the effectiveness of dampers used to suppress aeolian vibration on overhead lines. The method is applied to a Stockbridge damper and a simple picture is presented of the way in which this damper works. A second type of vibration damper is also considered, to demonstrate the way in which the performance of different dampers can be evaluated and compared using the new method.read more

On the computation of damped wind-excited vibrations of overhead transmission lines
TL;DR: In this article, the dampers are characterized by means of a 2×2 complex impedance matrix which can be experimentally determined in the laboratory and which includes the effects of the rotatory motion of the clamp.

Ein einfaches Rechenmodell zur Berechnung winderregter Schwingungen an Hochspannungsleitungen mit Dämpfern
TL;DR: In this article, the authors present a Weg eingeschlagen: Dampfungs-and Windleistung werden fur das halbunendlich bzw. unendlich lange Seil berechnet, was infolge des sehr dichten Spektrums der Eigenfrequenzcn des endlichen Seiles zu guten Ergebnissen fuhrt.
