Abstract

Solicitations induced by the passage of trains (wheels) on rail tracks are difficult to analyze, as there are many kinds of mechanical phenomena: impact, sliding and rolling. In order to make studies, the contact wheels/rails was simplified by a rig test which encountered a rigid steel disk to determine each mode of wear and fatigue. The model was built in the form of a machine-test. This paper presents a numerical  model of the rig test and results obtained are compared with the experimental data. A good correlation between numerical and experimental value of the dimensions of contact zone is obtained. The influence of contact parameters on the damage of the crossing material (Hadfield steel) was investigated by numerical model of the impact-sliding contact test.
