Higher modes of transmission lines with dampers

Journal of Sound and Vibration

Various forms of dampers are used to suppress vibrations in transmission lines. In the present paper a study has been made on vibrations of transmission lines having one or more dampers (Stockbridge type) near each end of the span for different cable lengths. An attempt is made here to study the effect of the location of dampers on maximum strains produced in the line. A comparative study of the maximum strains produced is also made for various wind power input assumptions. In addition, a finite difference method is used to find the natural frequency and a finite element method is used to find the natural frequency and mode shapes of the cable with and without a damper. © 1978 Academic Press Inc.

Transmission line vibrations

The aim of the present investigation is to establish a theoretical analysis of the response characteristics of Stockbridge dampers and to verify the theoretical predictions experimentally. Expressions have been derived for the response of the Stockbridge damper, by treating it as a two-degree-of-freedom system. The dynamic stresses introduced on the stranded cable are also theoretically determined. The experimental findings have been reported and explanations for discrepancies, where they occur, have been made. © 1973 Academic Press Inc. (London) Limited.
