FACTORS INFLUENCING PAPER MACHINE ROLL RELATED VIBRATION AND TECHNIQUES FOR THEIR IDENTIFICATION AND ANALYSIS

摘要

Vibration problems in paper machines continue to play a leading role in limiting their runnability, production speeds and operating efficiencies. The condition of paper machine rolls is the most dominant contributor to vibration issues and presents a myriad of challenges for both paper machine operators and roll manufacturers alike. The answers to these challenges lie in the use of a combination of test and measurement strategies that continue to benefit from advances in sensors and signal processing techniques. This paper discusses some of the primary factors leading to roll related vibration and offers insight into their identification and analysis.
