Original abstract
The load occur in the contact zone of the railway wheel and rail by the operation of rail vehicles. As a consequence of such a load is the contact fatigue of the material and the initiation of fatigue cracks and defects development. The numerical model for three different position of the rail and wheel were designed and the simulations of rolling and rolling with braking were performed for each model.
Czech abstract
Při jízdě provozu kolejových vozidel dochází v místě styku železničního kola a kolejnice ke kontaktnímu namáhání matriálu. Důsledkem tohoto kontaktního namáhání je únava materiálu vedoucí až k iniciaci trhlin a vzniku defektů. Byl vytvořen výpočtový model pro tři různé polohy kola vůči kolejnici a na každém tomto modelu byly provedeny simulace odvalování a odvalování s bržděním.
