TL;DR: In this paper, the performance of a multi recess worn hybrid conical journal bearing system compensated with an orifice restrictor changes appreciably as the wear depth parameter changes for the different values of semi-cone angle.
Abstract: Owing to their potential advantages including zero starting friction, low viscous running friction, high load carrying capacity, high stiffness and high positional accuracy, externally pressurized (or so-called hydrostatic) lubricated bearings are widely used in many applications. Conical hydrostatic bearings have been successfully used in various engineering applications, such as precision machine tools, for the advantage of being capable of carrying both axial and radial load. The combined effects of couple stresses, fluid inertia and recess volume fluid compressibility on the steady-state performance and the dynamic stiffness and damping characteristics of hydrostatic circular step thrust bearings are presented theoretically. Using a perturbation technique, results in terms of steady-state load-carrying capacity, oil flow rate, stiffness and damping coefficients are presented. The influence of worn defect parameter semi-cone angle on the performance of conical hybrid journal bearing system compensated with an orifice restrictor has been studied. This research concludes the performance of a multi recess worn hybrid conical journal bearing system compensated with an orifice restrictor changes appreciably as the wear depth parameter changes for the different values of semi-cone angle.

TL;DR: In this article, the application of piezoelectric actuators for active vibration control of rotating machinery is examined and the resulting predictions are shown to agree closely with results of tests performed on an air turbine driven-overhung rotor.
Abstract: The application of piezoelectric actuators for active vibration control (AVC) of rotating machinery is examined Theory is derived and the resulting predictions are shown to agree closely with results of tests performed on an air turbine driven-overhung rotor The test results show significant reduction in unbalance, transient and sub-synchronous responses Results from a 30-hour endurance test support the AVD system reliability Various aspects of the electro-mechanical stability of the control system are also discussed and illustrated Finally, application of the AVC system to an actual jet engine is discussed

TL;DR: In this article, a general analysis has been developed to computer simulate steady state and transient vibration phenomena of complex rotor-bearing support systems, and a central feature of this analysis is a proper handling of various highly non-linear effects (most notably journal bearings) which dominate the dynamic phenomena encountered during large amplitude rotor bearing vibrations.
