Abstract
A vibration absorber for attachment to suspended cables such as electrical transmission lines, to suppress vertical aeolian vibrations as well as horizontal subconductor oscillations. A clamp arm has one end attached to a suspended cable and a fulcrum adjacent the other end. The fulcrum is rotatably coupled to a frame, and the end of the clamp arm adjacent the fulcrum is coupled to the frame through two bellows elements which force air through small orifices to provide viscous friction when the clamp arm is caused to rotate relative to the frame as a result of said vibrations or oscillations. Each bellows includes a resilient pleated portion which acts to restore the initial orientation of the clamp arm.
