Originální abstrakt

The paper deals with numerical analysis of the process of roller straightening of rails. The problem of repeated elasto-plastic bending is solved by a program in MATLAB based on FEM algorithm with Eulerian description of material flow through the straightening machine. Beam element formulation with a shear deformation effect is used for the rail discretization. The results are compared with literature and standard FE analysis with Lagrangian description of material flow. Effectiveness of presented formulation is discussed and its applicability for fast iterative optimization of the straightening process is illustrated.

Český abstrakt

Příspěvek se zabývá numerickou simulací procesu rovnání kolejnic. Probém je řešen metodou konečných prvků v programu MATLAB. Algoritmus je založen na Eulerovkém popisu tečení materiálu skrz rovnací stroj. Výsledky jsou srovnané s literaturou a simulacemi získanými standardními MKP programy založenými na Lagrangeovském popisu.
