Ouantitative Relationships In Conductor Vibration Damping
(1955)
Abstract
Impedance matching relationships,
based on electrical-mechanical analogies,
are used to determine how the charac'
teristics of vibration dampers should be
related to the tension, weight per foot, and
diameter of conductors on which the
dampers are mounted, for optimum damping
of aenlia.n vibration. Methods of
detem1ining power dissipated in vibrating
conductors and dampers are developed.
Data on such power dissipation and on
nower input from wind to vibrating con):
turs are combined to obtain estimates of
' . .i:1ration amvlitude. The results of the
estimates are checked by comparison of
I'ecords of vibration of outdoor spans exposed
to wind.
