  • Auxiliary mass damper for slender flexible element subject to vibration
    Patent number: 5020644
    Abstract: Structures subject to seismic or other vibrations, such as structurally flexible elements of electrical and mechanical power plants, are effectively damped to reduce stresses resulting from such vibrations, by a system of auxiliary mass dampers. The dampers are advantageously connected to the regions of greater expected oscillation in response to such vibrations, to reduce structural stresses. A preferred auxiliary mass damper takes the form of a receptacle containing a fluent or granular material such as lead birdshot in mineral oil.
    Type: Grant
