OPTIMIZING THE WHEEL PROFILE TO IMPROVE RAIL VEHICLE DYNAMIC PERFORMANCE

A procedure for designing wheel profiles is presented which incorporates an analysis of the stability and curving performance of an idealized nonlinear rail vehicle model and the tendency of a profile to change shape with wear. The procedure is a closed-loop process implemented under operator control on a hybrid computer system. The vehicle performance for an initial profile is analyzed and the profile is systematically adjusted until dynamic performance and wear tendency objectives are met or have reached a successful compromise.
