Abstract
The wear of rails and wheels is important problem in rail traffic. The change of the shape of the wheel profile has not only a great influence on the dynamic properties of the vehicle (like stability, safety by passing curved tracks, etc.), but also affects the ride comfort of passengers and environmental insults, in extreme cases it can cause rail derailment. One of the ways to predict these undesired conditions are computer aided simulation analyzes. In this article are presented assessments of wheel profile wear by Archard wear law in Simpack simulation software, when is railway vehicle driving at different velocities.
Highlights
The dynamic behavior of rail vehicles on the track is significantly affected by the interaction between the wheel and the rail
Wear belongs to the degradation processes in which the material is discharged from the surface of one or both of the contact surfaces of rigid bodies which are in relative movement
The supplement for wear determination is in SIMPACK software embedded to the module SIMPACK RAIL, it is the determination of wear in the contact wheel-rail pair, where are the contact stresses solved by using the Kalker method named FASTSIM. [9,10] The developer motivated the application of supplement mainly to the issue of safety and maintenance, as is known, wheels and rails are subjected to wear and rolling contact fatigue (RCF) throughout their lifecycle, due the forces acting during frequent rail traffic
Summary
The dynamic behavior of rail vehicles on the track is significantly affected by the interaction between the wheel and the rail. In the depth of the examined issue is an understanding of the contact between the wheels and the rails. The impact of wear certainly affects the acoustic and vibrational expression of the car on the rail, which, by increasing the negative side, devastates the environmental environment around the tracks [1, 2]. Wear belongs to the degradation processes in which the material is discharged from the surface of one or both of the contact surfaces of rigid bodies which are in relative movement. The characteristic of the relative movement between the two entities in contact defines the wear process, in general. Over time the process of fatigue become separate scientific area named RCF (Rolling Contact Fatigue) [3,4,5,6]
