  • Patent number: 10605326
    Abstract: A mass damper system with a damper mass carrier having guide paths for receiving damper masses. The guide paths initiate swiveling movement at the damper masses around a center of mass during deflection of the damper masses. String lengths of imaginary string pendulums predetermine a position of respective coupling element configure the guide paths and the path curve is based on a first radial portion that extends from a central axis of the damper mass carrier to a connection point of a second radial portion and the second radial portion extends from the first radial portion to the center of mass. A ratio value is formed from a swiveling angle of the damper mass and its oscillation angle. A coupling element position in relation to the string length is determined by this ratio value.
