Research was conducted on non-contact transfer technology for applying magnetic levitation technology that uses electromagnets to thin steel plates. We previously succeeded in improving the levitation performance by bending a thin steel plate within a range that did not plastically deform it. In this study, to clarify the vibration mechanism of the steel plate during levitation, we performed a modal analysis, a frequency response analysis on a plate, and a bending and levitation experiment with a type of disturbance that has the most influence on such plates. As a result, it was found that the bending and magnetic levitation is effective for improving the levitation performance because the vibration mode became dominant when bending the thin steel plate and the levitation performance could be maintained even when the disturbance was input.
