Abstract
The continuous steel plate production line of the steel mill is several kilometers long, and the continuous steel plate is transported by contact support by rolls. In such a continuous steel plate transfer line by rolls, problems such as deterioration of surface quality due to contact between the steel plate and the roll can be mentioned. In our research group, we were able to obtain high induction performance in experiments by installing the electromagnet on the side of the steel plate on the path to convey the electromagnet. However, the shape of the steel plate has not yet been obtained analytically. Therefore, we are focusing on multibody dynamics and studying the optimal placement position of electromagnets. In this research, the restoring force of electromagnet unit in off‐plate direction was changed according to steady current. When the steady current increased, the vibration of continuous steel plate could be suppressed by the electromagnet unit. This tendency could also be obtained by free vibration experiments. From these results, the effectiveness of the proposed electromagnetic guideway was shown.
