Lubricated Contact Model for Cold Metal Rolling Processes
Numerical method for calculating lubricated contact pressures and friction in cold metal rolling is presented in this study. In order to have a good representation of the contact phenomena in lubricated metal rolling processes, interaction between surface roughness and lubricant flow has to be taken into account. Due to changes of lubricant thickness during the rolling process, lubricant flows in four local regimes: hydrodynamic thick and thin film, mixed and boundary regime. Ability to treat all four lubrication regimes is required. Surface roughness effects, lubrication regimes treatment and lubricant properties variations are all implemented within the present model. In order to calculate contact pressures and frictional forces, Greenwood-Williamson model with modified Reynolds lubrication equation is used. Finite Area Method is used to discretise Reynolds lubrication equation over a curved surface mesh. Implemented model is used as a solid contact boundary condition for a large strain elastoplastic deformation solver developed in foam-extend framework. The model is tested on wire and sheet rolling cases, and the results are presented here.
