In a plating process, the steel plate is conveyed 20â??50 m in the vertical direction for drying,\nduring which it is negligibly supported by rollers and other mechanisms. This produces plating\nwithout uniformity owing to the generation of vibration and other factors, which prevent the increase\nin productivity. We have developed a noncontact guide system for a high-speed traveling elastic steel\nplate in which electromagnetic forces are applied by actuators at the edges of the plate to control the\nplateâ??s position. In this study, we investigated the vibration phenomenon when changing the steady\ncurrent value of the electromagnet used for controlling the position. In addition, we conducted mode\nanalysis of the steel plate to enable stable control even at low steady current values and verified\nwhether stable guide can be provided by using it together with a permanent magnet. As a result,\nby arranging the permanent magnets, stable guidance was possible even at a low steady current\nvalue. In addition, it became clear that vibration damping performance is also improved.
