| dc.description.abstract | 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 | en_US |
