摘要：

An rotor-sliding bearing dynamics model supported on sliding bearing was established-D The dynamic model of the nonlinear rigidity-rotor system with rubbing fault was set up by the physics nonlinear factors. The nonlinear dynamic behaviors of the system caused by rubbing fault were studied by using the numerical value integral and Poincaré mapping methods. The bifurcation diagrams of the response were given following the changing of rotating speed-Aeccentricity and stiffness of the stator. Some typical Poincaré maps, phase plane portraits, trajectory of journal centers and amplitude spectra, et al, were also given. There are doubling-periods, approximate-periods and chaos behaviors in the rotor system. Which may provide theory references to fault diagnoses, vibration control, safety operating and enable early prediction of the fault in rotating machinery. © 2013 Asian Network for Scientific Information.
