...) finite element analysis bifurcation perturbation techniques machine bearings Load/unload (L/UL) systems are often preferred over contact-start-stop (CSS) systems because they allow the slider-disk contacts to be virtually eliminated. Moreover, this technology allows further reduction...

...J. K. Wang; M. M. Khonsari 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 pronounced influence on the bifurcation characteristics at the instability...

...J. K. Wang; M. M. Khonsari 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 based on the Hopf bifurcation theory. It is shown that the existence...

.... This point is the bifurcation point. The bifurcation point is located in the inlet of the lubrication film and outside of the Hertzian region. Due to continuity of the components of the lubricant velocity in the vicinity of the bifurcation point both u and v are small. Moreover, the bifurcation...
