A dynamic model of the rolling process. Part II: inhomogeneous model

The complexity created by applying the inhomogeneous deformation concept to the rolling process has been so overwhelming that, up to date, it was used only for the modeling of the static process. In order to study the chatter phenomena in rolling, however, a rolling process model with time-varying c onditions is required. A new dynamic rolling process model that utilizes th e inhomogeneous deformation concept and is capable of accounting for the in fluence of roll movements is presented in this paper. Finally, a brief disc ussion regarding the coupling of a suitable unsteady lubrication model, onc e developed, to the proposed inhomogeneous process model is given.
