  <dc:description>Wheel and rail is one of the most important material used to support and guide rail vehicle safely
and smoothly. Since wheel and rail suffers from various interacting mechanical and thermal
forces, friction modifiers, various contaminants and environmental atmosphere, wear poses large
Problem on wheel and rail.
Wheel and rail wear can be result in an extensive cost for truck owner, if it is not predicated and
prevented in an efficient way. To limit these costs, one measure is to predicate and prevent wheel
and rail wear through wear modeling.
The purpose of this research is to investigate the wear analysis on wheel / rail in rolling and
sliding contact using CATIA V5 R16 software and ANSYS 16.0 Workbench. The wear of the
wheels has been studies on stress structure as result and the analysis is done for two wheels
having different material composition (that is Bainitic steel which is new material and R7 which
is using by Ethiopian Light Railway Transit AALRT)
Using stress output as input for structural analysis different stress concentration are observed
The result obtained for the two wheels shows that wheel two has excellent hardness, strength and
have good resistance wear
Therefore, Bainitic steel can be applied to wheels in railway system</dc:description>
