Method of controlling legs of superconductively magnetically floating vehicle

Abstract

Abstract PURPOSE: To improve the vibration characteristics of a superconductively magnetically floating vehicle by detecting the angular displacement of the vehicle and so controlling the vehicle as to take off or land it by the leg moving speed corresponding to the intrinsic period of the vehicle vibration when the angular displacement of the vehicle is small. CONSTITUTION: When the running speed is decelerated at a superconductively magnetically floating vehicle, its magnetic attenuating characteristics becoms worse to cause the yawing angular displacement 4 of the vehicle to gradually largely vibrate at its intrinsic period T. When the running speed becoms V 1 and a leg movement start signal A becomes ON, the vehicle awaits until the angular displacement 4 becomes small and then starts lowering its legs. Since the leg moving speed is so set as to land the legs at half time of the period T, the vehicle lands at the running speed V 3 of small yawing angular displacement 4 and completes lowering of the legs at the running speed V 4 . Accordingly, the four legs do not collide irregularly at landing time so as to reduce the yawing vibration acted on the vehicle through the legs. COPYRIGHT: (C)1979,JPO&Japio
