Original abstract
The FEM study presented in this paper deals with a continuum mechanics approach to determination of the stress-strain behaviour in a newly designed shape of railroad wheel for different ways of ride. The reliability of the railroad wheel is related to achieved failures of material. This paper emphasises on the failures of material that are related to the first plastic deformation of the wheel material. This study focuses on designing the new shape of disc with a usage of special algorithm written for the ANSYS software and to determine an influence of stress waves in the material of the railroad wheel .This analysis gives answer to a rail-railroad wheel interaction on impact behaviour of a railroad wheel and a newly designed disc shape in different ways of ride. It shows the weak spots of the designed wheel.
Czech abstract
MKP studie uvedená v tomto dokumentu se zabývá přístupem mechaniky kontinua ke stanovení napjatosti a deformace v nově navrženém tvaru železničního kola pro různé způsoby jízdy. Spolehlivost kola souvisí s dosažením mezních stavů. Tento dokument klade důraz na mezní stavy, které se vztahují k první plastické deformace kola. Zde řešená analýza dává odpověď na interakci kolo-kolejnice z hlediska rázového chování s uvážěním nově navrženého disku kola pro různé způsoby jízdy, což dává odpověď na slabá místa navrhovaného profilu.
