AbstractThe presence of several rolls in cluster cold rolling mills makes on-line vibration monitoring and failure analysis difficult. The dynamic behaviour of rolls strongly depends on the rolling pressure in the roll bite. Strip vibration applies a dynamic component on the rolling force acting on the work roll and may excite the resonance of the mill stand.
