Abstract
- This paper presents a new deformation model for analyzing the asymmetric sheet rolling process in plane strain conditions. In the proposed deformation model, similar to the symmetric sheet rolling process, the sheet material between the upper and the lower rolls is divided into two deformation zones, i.e., entry and exit zones. The entry and exit zones are separated from each other by the line that connects the upper and lower neutral points. The mathematical equations of the two deformation zones are defined in a cylindrical coordinate system. The origin of the cylindrical coordinate system is located at the intersection of two inclined and vertical lines where the inclined line passes through the upper and lower neutral points and the vertical line passes through the first contact points of the sheet with the rolls. The proposed analytical model is based on the slab method for the analysis of asymmetric sheet rolling. The governing equations on the slabs are derived from the cylindrical coordinate system, and the roll force and the roll torque are calculated. The validity of the proposed model is discussed by comparing the theoretical predictions of the rolling force and the rolling torque with the results of other researchers and the FE simulation data obtained by the finite element analysis software DEFORM.
