Fundamental Considerations on the Changes in the Vibration Characteristics of a Flexible Steel Plate under a Magnetic Field Applied from the Edge Direction

Abstract

Thin steel plates are used in various industrial products such as automobiles. We proposed a magnetic levitation control system, and its realization has been confirmed through a digital control experiment. However, when only levitation control is applied to the steel plate, it has no horizontal restraining force on the direction of travel. Therefore, we installed electromagnetic actuators in order to control the horizontal movement of the levitated sheet steel. Electromagnetic control forces of the actuators are applied horizontally to the levitated sheet steel. This paper aims at reporting the effect of suppressing the elastic vibration of the steel beam in the electromagnetic field.
