On Advance in Leveling Process of Long Products

Popis výsledku v původním jazyce

This paper deals with advance in numerical simulation of leveling process of long products. The main task is useful setting of roller leveling machine to minimize residual curvature of a particular curved product. The problem is solved by program, usingsoftware MATLAB and fast algorithm which is based on the Finite Element Method (FEM) and its fundamental equation is set up. The curved material passes through laterally offset rollers with repeated elasto-plastic bending respecting the Eulerian approach. This results in convenient redistribution of residual stress which brings down the curvature of the product. The solution of this problem is complicated by high inherent nonlinearity and instability or sensitivity caused by cyclic plasticity of considered material. The problem is solved and useful setting is found by iterative process, based on input measured geometrical data and given material characteristics.
