Original abstract
The paper deals with numerical analysis of the process of roller leveling of long products. The problem of multiple elastic plastic bending is solved by a program in Matlab, which is based on the Finite Element Method. The aim is to provide a simple, user friendly tool, capable of quick and reliable analysis of the process without the necessity to work with large multipurpose FEM packages. Direct solution of the problem is formulated, starting from the roll intermeshing and product geometry. Roller loading, product deflection, curvature and plastification are the output parameters of the program. With fast and reliable solution of the direct problem, optimal setting of the leveling process will be sought in an iterative process.

Publikace se zabývá numerickou analýzou procesu rovnání dlouhých produktů. Problém mnohonásobného elasto plastického ohýbání je řešen programem v MATLABu, který je založen na Metodě Konečných Prvků. Cílem je poskytnout jednoduchý, uživatelsky přívětivý nástroj, schopný rychlé a spolehlivé analýzy procesu bez nutnosti pracovat s velkými víceúčelovými MKP balíky. Přímé řešení problému je naformulováno a začíná od přesazení válců a geometrie produktu. Výstupními parametry programu jsou zatížení válci, průhyb produktu, zakřivení a plastifikace. Rychlé a spolehlivé řešení přímého problému, optimální nastavení rovnacího procesu, bude hledáno iterativním procesem.
