Original abstract
Problem of wheelset rolling on rails is commonly solved problem of engineering practice. Only ideal geometry of the wheelset is used in majority of studies to simulate its movement. However, shape irregularities appear as a result of wear and they have a great influence on the movement. In this paper a model is presented which can be used to simulate wheelset movement in the three dimensional space. Shape irregularities are implemented into the model and diverse ways to calculate the contact forces are presented and compared with respect to accuracy of results they provide and their demands on computer equipment.
Czech abstract
Problematika pohybu železničního dvojkolí po kolejnicích je v inženýrské praxi často řešen. Většinou se používá pouze idealizovaná geometrie dvojkolí. Ve skutečnosti se však na dvojkolí vytvářejí odchylky tvaru jako důsledek opotřebení, které mají značný vliv na pohyb dvojkolí. Tento článek prezentuje model, který lze použít k simulaci pohybuje ve trojrozměrném prostoru. Tvarové odchylky jsou implementovány do tohoto modelu a různé způsoby stanovení kontaktních sil jsou prezentovány a srovnány s ohledem na přesnost výsledků a nároků na počítačové vybavení.
