Optimization the technological parameters of elastic-plastic bending of long sized skins and panels of variable curvature

Features of existing methods of determination the technological parameters of elastic-plastic bending are described. The method of determination the correction coefficients for increase the accuracy of calculation the run of a press roll (press punch) by a method of final element modeling is given. The way of definition the law of press roll vertical movement change, providing uniformity of the received radius of curvature upon transition from symmetric to the asymmetric scheme of loading at bending-rolling is described.
