Dynamic Performance of Turbocharger Rotor-Bearing Systems
… to measure dynamics of differing turbocharger rotor bearing systems and to develop a coupled rotor-cartridge model for the ball bearing rotor system to corroborate the experimental and analytical results. The ball bearing rotor is supported by an angular contact ball bearing cartridge. In order …

Advanced analysis of rotor-bearing systems for stability and response
Rotor dynamics has become an integral part in the analysis and design of industrial turbo machinery. Rotor dynamics deals predominantly with the evaluation of the stability and damped critical speeds, and the response to an unbalance excitation, of turbomachinery. The majority of the industries …

Synchronous Thermal Instability Evaluation of Medium Speed Turbocharger Rotor-Bearing Systems
Rotors in fluid-film bearing supported turbomachinery are known to develop elliptical orbits as a result of rotor-bearing interactions, mass unbalance within the rotor, gravitational bending of the shaft and external excitation. In synchronous whirl, where the speed at which the shaft travels about …

On the stability of rotor bearing systems based on Hopf bifurcation theory
… is aimed to establish instability criteria for a rotor-bearing system which consists of a rotor supported by two fluid-film journal bearings. The static and dynamic characteristics of rotor-bearing systems with consideration of turbulent effects are evaluated by applying the Hopf bifurcation …

Critical speeds and unbalance response of cantilever-sleeve rotors using finite elements with efficient higher order basis functions
Design of industrial rotor-bearing systems requires an understanding of their dynamic behavior, which involves the determination of their critical speeds and unbalance response. Dynamic behavior of simple rotor systems can be studied using analytical techniques. However, for complex rotor systems …

Morton Effect Induced Instability in Mid-Span Rotorâ Hydrodynamic Bearing Systems
The Morton Effect in the rotor - bearing systems may lead to an unstable operation. Up to the present, most of the established research efforts have been focused on the overhung rotor systems. In this dissertation, a systematic study on the Morton Effect induced instability in mid-span rotor …
