抄録

In the conveyance manufacturing process of thin steel plate, the quality of the plate surface deteriorates because the plate is usually in contact with the rollers. To solve this problem, electromagnetic levitation technologies have been studied. However, when an ultrathin and flexible steel plate is to be levitated, levitation control becomes difficult because the ultrathin steel plate undergoes increased flexure. We have proposed the levitation of an ultrathin steel plate that is bent to an extent which does not induce plastic deformation. In this study to elucidate the levitation stability under disturbance, random disturbance was input into the levitation system and bending levitation experiments were carried out using the ultrathin steel plate with a thickness of 0.18 mm.
