The service life of locomotive wheels, rail is largely dependent upon cracks initiation and propagation. The determining factors for these two parameters are contact stresses between locomotive wheel and track. The research investigates the stresses generated in locomotive wheel under dynamic conditions. Finite Element Analysis is conducted using ANSYS software for locomotive wheel under transient structural conditions. CAD model of wheel is developed using Creo 2.0 design package. The design optimization of locomotive wheel is then conducted using response surface method and parameters selected for analysis are hub inner radius and hub outer radius. The findings of the research provide necessary design modifications to minimize stresses generated and mass. The sensitivity of both the design parameters with respect to output parameters is also evaluated.
