| Outline of Final Research Achievements |
This research subject includes two topics: A maglev system using magnetic fluid (MF) as a levitated object and a maglev vehicle that can respond to changes in the shapes and properties of the opposing surface. In the former, we established a levitation procedure for a placed MF droplet. Also, we derived the relationship between the levitated droplet's volume, viscosity, deformation state, and the magnetic force equation. Moreover, we have shown that a positioning-controlled MF cone can be manipulated vertically or horizontally and reciprocated at high speed. In the latter, we fabricated a device that can handle various opposing surfaces. It was demonstrated that the device could float stably under flat plates, cylinders, and straight and curved rails. In addition, we proposed a method to remove the influence of non-uniform conductivity and magnetism on the opposing surface. As a result, our device successfully passed through the non-uniform area while keeping contactless levitation.
