Abstract

A simulation of the deformation of a workpiece with a U-shaped cross section in a three-roll bending process is performed. Based on the properties of the workpiece, the distribution of curvature and bending moment are calculated in accordance with the displacement and the rotation of the rolls. The relationship between the position of the rolls and the final curvature of the workpiece is obtained. An experiment is performed and the accuracy of the simulation is confirmed.
