ELECTROMAGNETIC VIBRATION SUPPRESSION DEVICE AND ELECTROMAGNETIC VIBRATION SUPPRESSION CONTROL PROGRAM

摘要

Provided is an electromagnetic vibration suppression device that eliminates a special edge position detection sensor and can appropriately suppress the vibration of not only a steel plate traveling with a normal posture but also a steel plate traveling while meandering in a width direction. Also provided is an electromagnetic vibration suppression device that can appropriately suppress the vibration of a steel plate being curved in a thickness direction and traveling while meandering in a width direction. The electromagnetic vibration suppression device (1) has a plurality of pairs of electromagnets (2) (2A, 2B) arranged in a width direction of a steel plate (Sa) traveling in a predetermined direction, each pair being disposed facing each other in a thickness direction of the steel plate (Sa), and suppresses the vibration of the steel plate (Sa) traveling between the electromagnets (2A, 2B) of each of the pairs of electromagnets (2) by a control unit (4) for controlling the current flowing through each of the electromagnets (2A, 2B). The control unit (4) obtains an edge position (Sae) of the steel plate (Sa) by a calculation based on the input width dimension of the steel plate (Sa) and the meandering amount of the steel plate (Sa) input in real time or at predetermined intervals of time, and separately controls, according to the edge position (Sae) of the steel plate (Sa), the amounts of currents to be flowed through the respective electromagnets (2A, 2B).
