Impact of journal bending on the failure of axle bearings in railroad passenger cars

Abstract: This research presents a systematic methodology to analyze the failure mechanism of cylindrical roller bearings of railroad passenger cars. Initially, a finite element model is developed to calculate the journal bending and internal contact load distribution, considering multi-interfacial contact parameters. Then, non-Hertzian contact theory is applied to prove the rollers’ abnormal contact behaviors, including load-distribution and displacement. Subsequently, a grease lubrication model is developed t… Show more
