Bending Magnetic Levitation System of Flexible Steel Plate

(Fundamental Consideration on the Dynamic Behavior of Levitated Steel Plate under the Input of Sinusoidal Disturbance)

Abstract

　In recent years, demand for thin steel plate used in automobiles and home appliances has been increasing. In the steel plate manufacturing process, deterioration of surface quality due to contact between rollers and steel plate has become a problem. As a solution to this problem, research has been conducted on non-contact conveyance using magnetic levitation technology. However, when flexible thin steel plates are used for levitation, it is difficult to control levitation due to large deflection. Therefore, our research group has proposed a Bending magnetic levitation system using bending flexible steel plates and has confirmed that levitation is stable. However, the behavior of the steel plate during levitation has not yet been fully clarified. In this study, the vibration characteristics of flexible steel plates were investigated from the dynamic behavior of the steel plates by applying a disturbance to the plates during bending magnetic levitation.
