Energy-Efficient Trajectories Rotors Supported on Radial Fluid-Film Bearings

Abstract

The problem of rotor machines modification requires development of new approaches to the design of specific nodes. As bearings are considered to be the most important elements of rotor machines, such approaches can imply optimization application. The present paper considers the approach for enhancing energy efficiency of rotor machines by means of generating optimal trajectories using the example of fluid-film bearings. The authors provide the means to analyze the obtained trajectories types. The paper also covers the approach for setting the criteria of rotor’s trajectories energy efficiency. Besides, the paper presents the results of the conducted numeric analysis that led to the hypothesis about the existence of non trivial rotor energy-efficient orbital trajectories.
