Abstract

The present paper deals with a sequential fluid structure strong coupling approach in order to solution the roughness prediction. The cold rolling model involves the strip with its asperities, the lubricant and the working roll. The strip asperities are modelled in 2D (trapezoidal shape) forming valleys and plateaus. Fluid flow rate between each valley full of lubricant is solved using Reynolds equations. Thus, the volume of lubricant trapped and its pressure are updated on the cold rolling model. During computations, the asperity is deformed from the entry to the exit to obtain its final shape. Global parameters such as front, back tensions, speeds are taken into account but also rheological (fluid, solid) and tribological behaviours.
