  • Patent number: 6102379
    Abstract: A metal spring with embedded constrained layer damping provides effective damping of a supported load. A continuous load bearing tube is provided with an inner diameter and an outer diameter with a plurality of constraining layer tube sections concentric with the load bearing tube and spaced along the load bearing tube. A damping layer of a viscoelastic material contacts facing surfaces of the continuous load bearing tube and the constraining layer tube sections so that shear strains are induced in the viscoelastic material from relative rotation of the load bearing tube and the constraining layer sections to provide damping of an applied load. In one embodiment, the constraining layer tube sections and damping are within the load bearing continuous tube and the continuous tube is sealed at each end to permit use of the spring in a vacuum environment.
