The transverse vibration of high-speed rolls

Abstract

The transverse, dynamic deflection of high-speed, wide-faced, composite tubular rolls is investigated. General procedures are proposed enabling the analysis of inter-connected units comprising both distributed parameter and rigid, pointwise models. Modelling methods, eliminating intermediate variables are employed facilitating the realisation of an overall system, input–output representation. Illustrative studies, detailing the analysis and evaluation process are presented. A high-speed, paper making machine, table roll application is considered. Whirling conditions and the effect of this problem on sheet quality and manufacturing output is commented upon.
