COULOMB-TYPE VIBRATION ABSORBER FOR SUSPENDED CABLES AND SINGLE SUSPENDED CABLE COMBINED THEREWITH

摘要

COULOMB TYPE VIBRATION ABSORBER FOR SUSPENDED CABLES AND SINGLE SUSPENDED CABLE COMBINED THEREWITH A vibration absorber for attachment to a single conductor suspended transmission line, to suppress vertical aeolian vibrations. A clamp arm has one end attached to a suspended cable and another end rotatably coupled to a housing having a weight extending therefrom, through two frictionally-engaged elements which provide coulomb friction when the clamp arm is caused to rotate relative to the housing as a result of said vibrations. A separate resilient member couples the clamp arm to the housing to restore the initial orientation of the clamp arm.
