ABSTRACT:
An apparatus for damping mechanical oscillations vibrations or pulstations with magnetic suspension railways having vehicles movable to float along elevated tracks using magnetic levitation or suspension technique as well as having supplemental suppression device suppression devices to eliminate oscillation. Each supplemental oscillation suppression device has an additional mass in the form of a hollow body or solid material, and is suspended by means of steel or rubber springs on the longitudinal vehicle support or on the longitudinal track beam. One end face of that supplemental oscillation suppression device associated with the vehicle is provided with a buffer in the horizontal plane of the longitudinal axis thereof, and respective stops are arranged on both longitudinal sides and are fastened to the longitudinal support, with the end face of the hollow body facing the buffer being closed by a base plate, the opposite end face being tightly closable with a screw cap. That supplemental oscillation suppression device associated with the track is fastened in a free-swinging manner within the box profile of the longitudinal track beam and on the top chord thereof. The web plates are provided with openings for inserting the supplemental oscillation suppression device.
