Abstract: A method is presented for predicting the occurrence of a hysteresis phenomenon, which is observed in experimental results dealing with the instability of rotor-bearing systems. The method is ...

Abstract: The existing literature contains a number of disparities in assessing the effect of inlet oil temperature on the instability threshold speed in hydrodynamic journal bearings. Specifically, some ...

Abstract: The effects of rotor stiffness on the bifurcation regions of a flexible rotor supported by two identical fluid-film journal bearings are presented. It is shown that the rotor stiffness has a ...

Abstract: A method is developed for predicting the stability envelope of a rotor-bearing system using the Hopf bifurcation theory. Results are compared to published literature obtained using a trial-and-error ...
