| Abstract: | With the co-operation between the small stiff convexes and small plastic convexes, the co-operation between rolls and rolled piece has been simulated. Combining the up-bound method with the slipping-line method, the model of micro shape on the touching surface has been optimized. The influences of the micro geometry shape of small convexes and the joint strength between convexes on the frition factor are studied. |
