Vibration Analysis Executive Summary Vibration is increasingly becoming a problem as machine speeds have increased and paper quality requirements have risen along with increased competition. Balance grade G1 is requested and more time is spent on balancing the rolls in the machine. However, by balancing, mills typically measure only the The 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.
An effective signal processing method can provide more evident information from vibration signals. Thus, there is a considerable interest in vibration analysis and signal processing in this area [14, 15, 17, 24-26]. Investigation of the dynamic behavior of cold rolling mills is the main objective of this research.
