Abstract
The dynamic behaviour of an axially moving viscoelastic band, in contact with supporting rollers, is studied. A model of a thin, viscoelastic beam (panel) subjected to bending and centrifugal forces is used. An initial-boundary value problem for a fifth-order partial differential equation describing the movement of the band is formulated in detail. In this paper, five boundary conditions in total are used for the first time within the present model. An external force describing the normal force of the roller supports is included. Combining this viscoelastic model with the roller contact simulation is a new approach among moving band behaviour studies. The initial-boundary value problem is solved numerically using the fourth-order Runge-Kutta method and the central finite differences, and the band behaviour is illustrated for different band velocities and degrees of viscosity. It is found that the damping effect of viscoelasticity increases when the band velocity increases, and that the roller contact has a greater effect on the elastic panel behaviour than on the viscoelastic panel behaviour.
