Control of rotor motion using active fluid-film bearings

Abstract

The article focuses on active rotor supports based on the fluid-film bearings. Several approaches to design of such bearings are shown, a more detailed design of an active hybrid bearing with controllable lubricant supply pressure is presented. A certain approach to mathematical modeling of a rotor system with an active radial hybrid bearing is reviewed. Corresponding results of mathematical modeling are shown. A conclusion on efficiency, as well as prospects of further research in this field, of such bearings is made. Moreover, peculiarities of active fluid-film bearings are studied. Prospects of intellectualization of rotor motion control systems are reviewed. A structural diagram of a rotor motion control system, where methods commonly referred to as artificial intelligence are used, is presented.
