Fundamental Analysis of Suppression Effect of Elastic Vibrations with Magnetic Force of Permanent Magnets Applied Horizontally to the Edge of Magnetically Levitated Steel Plates

摘要

We have proposed a magnetic levitation control system for a steel plate and confirmed experimentally the feasibility. However, the case in which only the levitation control is applied for the steel plate, it has no horizontal restraining force in travelling. And so, the electromagnetic actuators are installed in order to control the horizontal position of the levitated steel plate. The electromagnetic attractive forces are given to the faced two edges of the plate. In this paper, the suppression effect of elastic vibration of the plate in the horizontal noncontact positioning control is reported. The results of experiment show that the elastic vibration of the levitated steel plate can be sufficiently suppressed.
