ABSTRACT OF THE DISCLOSURE A coulomb-type vibration absorber for suspended cables, comprising a frame, a first annular member secured to said frame and having an exposed frictional surface; a clamp body having a first portion for engaging a cable in a predetermined position and a second portion rotatably mounted to said frame for rotation of said clamp body about an axis generally parallel to said predetermined position of said cable; a second annular member secured to said second portion of said clamp body, and having an exposed frictional surface in rotating frictional engagement with said exposed frictional surface of said first annular member; resilient means for coupling said clamp body to said frame; and means for adjusting the coulomb frictional force between said exposed frictional surfaces, said frictional force generating frictional losses upon vibration of said cable which substantially exceed any hysteresis losses within said annular members, so that the coulomb frictional force between said first and second annular members provides dissipative damping for both said cable and said resilient annular members.
