Original abstract
The FEM study presented in this paper deals with a continuum and fracture mechanics. The stress-strain behaviour in the railroad wheel with primary crack in case of a straight ride can be assessed. The primary cracks are often in the rail wheels; therefore, impact behaviour is common plot. For this reason, the influence of impact behaviour on the railroad wheel has been observed. The analysis will affect some selected cases of straight ride which are important in terms of loading.
Czech abstract
Studie pomocí MKP uvedená v této práci se zabývá problematikou mechaniky kontinua a lomové mechaniky. Je hodnoceno napěťově-deformační chování železničního kola s primární trhlinou pro případ přímé jízdy. Trhliny jsou častým jevem v železničních kolech a rázové chování je proto častým jevem. Z tohoto důvodu byla řešena problematika rázového chování. Analýza postihne takové vybrané případy, které jsou z hlediska zatěžování pro případ přímé jízdy podstatné.
