摘要
This paper presents a novel multi-scale method to investigate the interface pressure and friction in a 3D model of cold strip rolling. The key innovation is the introduction of an equivalent interfacial layerl to integrate the effect of lubricant with surface asperity deformation. This multi-scale method also enables to capture the microscopic roll-strip interface deformation associated with the random asperities and to treat all the lubrication regimes from hydrodynamic lubrication to mixed and boundary lubrication in a single program. The proposed method can predict well the experimental measurements, and is applicable to other contact sliding processes involving complex lubrication regimes. (C) 2014 Elsevier Ltd.
