Ouantitative Relationships in Conductor Vibration Damping
(1956)
Abstract
Impedance matching relationships,
based on electrical-mechanical analogies,
are used to determine how the characteristics
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 aeolian vibration. Methods of
determining power dissipated in vibrating
conductors and dampers are developed.
Data on such power dissipation and on
power input from wind to vibrating conductors
are combined to obtain estimates of
vibration amplitude. The results of the
estimates are checked by comparison of
records of vibration of outdoor spans exposed
to wind.
