Abstract In this paper the authors present a theory of the action of friction dampers on systems in torsional resonance, with special application to gas- and Diesel-engine installations. Model tests carried out to check this theory are described. The effect of introducing springs in the Lanchester damper is also discussed.

A vibration damper for cables utilizing the frictional properties of a close-wound spiral spring, that is, a spring wound in spiral form from a flat strip and having contacting faces. Vibrational energy is dissipated in the spiral spring by the lateral motion of the turns of the spring relative to one another.
