On flow-induced vibrations of overhead transmission lines

Abstract

The history of flow-induced vibrations dates back to the ancient Greek and their aeolian harp with wind driven strings. Indeed, one technically important type of vibration of overhead transmission lines is exactly due to this very effect of a Von Karman street of shed vortices coupled to elastic vibrations of the cable. Other aeroelastic phenomena associated with overhead transmission lines are galloping, wake-induced flutter, and buffeting.
