Dynamic behaviour of an axially moving multi-layered web

A new approach to the analysis of the dynamic behaviour of an axially moving composite web is presented. The mathematical model of the moving web system constitutes non-linear, coupled equations governing the transverse displacement and stress function. The calculations are carried out for two paperboard structures. The results of numerical investigations show solutions to linearized problems. The effect of paperboard properties and axial transport velocity on flexural and torsional vibrations are presented.
