Abstract

A brief description has been given of the original software product, the Bearing-Builder Finite-Element Method, and its application for analyzing the hydrodynamics of cylindrical friction bearings during dynamic loading. A two-dimensional problem about the flow of lubricating liquid in the bearing clearance is solved using the finite elements method, which takes into account the constructive and technological peculiarities of the real bearing into, including the groove for oil supply, ellipticity, conicity, barrelicity, shaft faceting, etc. The role of exploitation factors that lead to deviations from the initial cylindricity of bearing in the form of fatigue defects and wear tracks was analyzed. The examples of calculations that demonstrates the user options of the Bearing-Builder Finite-Element Method program were shown.
