Axle burn-off and stack-up force analyses of a railroad roller bearing using the finite element method

Railroad bearing-related failures are a primary concern to the railway industry. A bearing-related failure can cause derailment and result in millions of dollars in damage. The bearings used in railway applications are almost exclusively tapered roller bearings and are composed of a two-row assembly with a single element containing the outer race for both rows of rollers (the cup) and separate elements for the inner races (the cones). From a reliability standpoint, the bearing-axle assembly may be the most critical component on a rail car. A bearing under loose-cone conditions is prone to internal seizure which can result in an axle burn-off, one of the most detrimental of railroad failures.
