文摘This paper presents the instability analysis of unsymmetrical rotor bearing system in accordance with the Campbell diagrams of the system, and concludes that the unstable regions stay in high speed regions with the increase of supporting stiffness and they decrease or disappear with the decrease of the inequality diametrical moments of the inertia and stiffness of shaft.
