The paper will study the influence of material on surface damage on the wheel - rail materialsrnThe study begins with identifying basic criteria to select an appropriate steel materials for wheelrnand rail among different alternatives. The basic criteria are cost, material compositions,rnmechanical properties such as tensile strength, proof load, fatigue strength, toughness by using therncriteria two pair of wheel- rail material selected (AS4140-V1657) and (C74-U75V) comparingrnwith AALRT wheel - rail material (CL60&U71MN)rnNext analyzing and identifying the stresses on the wheel â€“rail contact due to the load to predictrnand minimize failures caused. the 3D model has done on modeling package of CATIAV5R16.rnAssembly model has created in assemble workbench of CATIA after individual wheel and railrnhad created on part work bench after the assembly is accomplished on CATIA. it was imported inrnto the ANSYSR14.5 to analyze the stress caused by vertical load. During the analysis ofrnwheel/rail contact in ANSYS software, the parameters have been used axle load, displacement,rnheat fulx, heat convection.rnFrom ANSYS software simulation the results obtained for the one wheels-rail contact show that,rn(AS4140&V1657) has excellent strength, toughness and good resistance to thermal damage duernto better hardness than (CL60-U71MN ) &(C74&U75V). Therefore, the (AS4140&V1657) steelrnmaterials can be applied to wheel - rail in the railway systems.
