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, point-wise models. Modelling methods, eliminating intermediate variables are employed facilitating the realization of an overall system, input – output representation. An illustrative study, detailing the analysis and evaluation process is presented. A high speed, MG 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.

Abstract: Distributed-lumped parameter modelling methods are employed in the analysis of manufacturing machine drives comprising rotors, bearings and shaft arrangements for variable speed process systems. Analysis procedures enabling the computation of the torsional shear stress and velocity response of these systems are outlined and block diagram representations are formulated. The dynamic stresses for machine drive arrangements following deterministic input changes are computed. Typical rotor-shaft assemblies are investigated illustrating the peak stress levels encountered.
