Abstract
The present invention presents a novel system and method of damping rolling, pitching, or yawing motions, or longitudinal oscillations superposed on their normal forward or backward velocity of a moving levitated system.
Claims23
A magnet rail damping system, comprising;
- a track circuit configured between one or more pair of Halbach arrays, wherein said track circuit further comprises a plurality of predetermined transverse cuts to periodically separate said track circuit at desired intervals so as to produce a plurality of short tracks;
- and
- one or more dampers, wherein each said damper comprises:
- a) a support shaft;
- b) a fixed friction disc coupled to said support shaft;
- and
- c) a movable friction disc coupled to said support shaft and additionally coupled to an inner edge of said short track.

A method for suppressing induced oscillations of a magnet rail system, comprising;
- positioning a track circuit between one or more pair of Halbach arrays, wherein said track circuit further comprises a plurality of predetermined transverse cuts to periodically separate said track circuit at desired intervals so as to produce a plurality of short tracks;
- coupling one or more dampers at each of said short tracks so as to suppress unwanted vertical, horizontal, and longitudinal induced oscillations in said magnet rail system, wherein each said damper comprises:
- a) a support shaft;
- b) a fixed friction disc coupled to said support shaft;
- and
- c) a movable friction disc coupled to said support shaft and additionally coupled to an inner edge of said short track.
