Calculation of Synchronous and Asynchronous Rolling with Plane Rolls by RFEM

Great progress has been made in the study of asynchronous rolling, but these studies are rather rough because the method used are not so suitable. It is difficult to describe the deformation in detail without the analysis of stress-strain fields. In this paper the roll force,specific pressure distribution, stress-strain-strainrate fields are obtained using RFEM. After analyzing the results, we obtained the following conclusions:In strip rolling the friction exerts a great influence on the pressure distribution.Comparing the asynchronous rolling with the normal rolling, the characteristics of them are different. The stress distribution in the deformation zone, and the direction and value of shear stress have been changed during asychronous rolling, this change makes the roll force decreasing, it is known as action of "cutting peak".
The behaviour in asynchronous rolling(such as "bending"of rolled-piece etc.) is explained using the calculating results yet.
