Abstract

The finite element method was employed for developing new designs of railroad car wheels. The problem was formulated in general terms, the region at hand discretized, and the contact problem and the heat conduction problem were solved for which the boundary conditions were assigned. The numerical solution error was determined. Mathematical modeling of various wheel designs was carried out, and CAD-enhanced wheels were rolled. The effectiveness of the new wheel designs was validated in service tests. 1 Introduction The railroads are responsible for the major part of loads carried in the Newly Independent States. No high-speed transportation exists in the region, and the majority of merchandise is transported by heavy-load railroad stock (up to 25 t per axle). Hence, the use of
