Abstract: Thin steel plates are widely used in various industrial
products. However, there are problems where deterioration of surface quality
and metal plating occurred by transporting. As a solution to these problems,
a noncontact transport of steel plate using electromagnetic force has been
proposed. However, there is a risk that side slipping or the dropping of the
plate may occur. Therefore we have proposed the addition of electromagnetic
actuators to control the horizontal motion of levitated steel plate. In this
study, a thin steel plate (0.24 mm thickness) was magnetically levitated,
and we carried out transport experiments to discuss the effect of a magnetic
field from horizontal direction applied to the levitated steel plate on its
elastic vibration. As a result, it is confirmed that the application of a
magnetic field in the horizontal direction improves the levitation stability
of transported thin steel plate.
