Experimental Consideration on Suppression Effect of Elastic Vibration in Electromagnetic Levitation System for Flexible Thin Steel Plate with Curvature

Abstract

Recently, research on non-contact conveyance systems using electromagnetic levitation technology has accelerated. We have constructed an electromagnetic levitation control system that keeps the relative distance between the electromagnet and steel plate constant. To investigate the levitation stability of thin steel plates, we performed magnetic levitation experiments on a thin steel plate with curvature. A physical disturbance was applied to the electromagnet units by vibrators. The electromagnet units were vibrated up and down by a vibrator. We investigated whether the bending magnetic levitation improved the levitation performance even if the magnetic levitation system was in a vibrating environment. We determined that it was possible to realize stable levitation for a steel plate under external disturbances during levitation at the optimal bending angle.

Basic Study on Mechanical Vibration Suppression System Using 2-Degree-of-Freedom Vibration Analysis

“…Recently, many methods have been used to obtain the vibration characteristics of structures, such as obtaining the eigenmodes of structures or resonance points using direct numerical integration [12][13][14][15][16][17][18][19][20][21]. However, it is very difficult to obtain the mode in the case of the forced vibration response when the object undergoes real vibrations such as vibrations during the operation of the machine or control output.…”
