Approaches to modeling occurrence of rolling contact fatigue damages in rails
Вестник Научно-исследовательского института железнодорожного транспорта, 2018 Rolling contact-fatigue damages of rails along with their wear are the most common types of rail defects. In recent years, there have been significant changes in the distribution of rolling contact fatigue damages of rails especially on railways ...

Test Modes for Establishing the Tribological Profile under Slip-Rolling
Lubricants, 2020 The complex nature of slip-rolling contacts in many applications such as gear tooth flanks, rolling bearings, and heavy machinery often makes determining the friction and wear properties, as well as the fatigue resistance, of tribosystems difficult.

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2014 A simulation of the rolling contact fatigue strength of a traction drive element was developed. This simulation accounts for both the distribution of sizes of inclusions in the element material and the influence of traction forces at the element surface.

Fatigue Life Analysis of Rolling Bearings Based on Quasistatic Modeling
Shock and Vibration, 2015 Rolling bearings are widely used in aeroengine, machine tool spindles, locomotive wheelset, and so forth. Rolling bearings are usually the weakest components that influence the remaining life of the whole machine. In this paper, a fatigue life prediction

Fatigue Life Prediction of Rolling Bearings Based on Modified SWT Mean Stress Correction
Chinese Journal of Mechanical Engineering, 2021 The existing engineering empirical life analysis models are not capable of considering the constitutive behavior of materials under contact loads; as a consequence, these methods may not be accurate to predict fatigue lives of rolling bearings.
