Abstract : Railways are using different types of wheel profiles which include Parabolic, Straight plate and S-shaped profiles. The type of wheel profile effects the stress distributions, temperatures, natural frequencies according to the static, dynamic and thermal loading conditions applied on it. In this present paper the straight plate-Shaped locomotive wheel profile is considered for the study. The straight plate shaped wheel profile has been developed by using commercial tool CATIA V5 which is modeled as Axi-symmetric model. We have chosen the AAR class C high carbon steel, ASTM A897 grade5 (230-185-00) Austempered ductile iron (ADI) and Aluminum silicon carbide materials for this study so as to check the feasibility of other materials for railway wheel other than steel. Static, Modal and thermo-mechanical analyses are conducted by using finite element analysis commercial tool ANSYS 15.0. 2-D Axi symmetric analysis is chosen for the wheel profile in ANSYS. The stress distributions, displacements are analyzed in Static analysis. The natural Frequencies and mode shapes are analyzed in Modal analysis. Stresses and displacements due to both mechanical and thermal loads will be analyzed from the Thermo mechanical analysis. Comparison of stresses, displacements and natural frequencies for the straight plate-Shaped wheel profile are studied to determine the better material for the wheel profile. Keywords - Straight plate shaped locomotive wheel profile, Stress concentrations, Displacements, Natural frequencies, ANSYS 15.0.
