IMPACT BEHAVIOUR OF A NEWLY DESIGNED RAILROAD WHEEL


Abstract eng:
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.
