| Summary: | 碩士 === 國立高雄海洋科技大學 === 輪機工程研究所 === 100 === This research has developed a magnet levitation device, which forms magnet repulsive forces between two opposite poles of two pairs of floating rectangular magnet sets.
A high speed motion platform is used to produce desired foundation acceleration and to study the acceleration reduction properties of the magnet levitation device. Comparisons with the acceleration reduction rates of a driver seat designed for high speed boats (a dual acceleration- reduction device of hydraulic damper and double-cantilever plates) and with that of a hybrid devices were made.
The tendency of the magnet levitation devices in lateral rotation, in terms of rolling angle, due to an unbalanced weight distribution or external forces has also been studied/simulated using Ansoft Maxwell 3D software package.
The experiment and analysis results indicates that (1) the acceleration reduction rate of the magnet levitation devices is higher than that of the dual acceleration-reduction device; (2) the hybrid device of the magnet levitation device and the dual acceleration-reduction device provides the highest acceleration reduction ratio; (3) the rolling angle of the floating magnet levitation will be small when lateral rotation occurs due to unbalanced weight distribution or external forces; and (4) the magnitude of the magnet forces of the levitation device will be influenced by the geometry and arrangement of the magnets.
