The vibration absorber comprises a mass, a drive and a control device. The mass is coupled without using a spring and through the drive to a fastening means for fastening the drive to the support structure, so that upon a movement of the mass relative to the fastening means an inertial force caused by this movement is directly transmitted through the drive to the fastening means. The control device comprising a motion sensor is adapted to control the drive in function of a signal from the motion sensor. The active vibration absorber is designed to damp especially low-frequency vibrating structures including more than one mass-spring element so that the vibration amplitude thereof is significantly reduced."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Active absorber for low-frequency vibrating structures","description":"An active vibration absorber is provided for damping vibrations of a cantilevered portion of a support structure.
