Abstract: Presents the dynamic behavior of a rotor-elliptical journal bearing system with nonlinear fluid film forces obtained using the database method, and the bifurcation diagrams, the time histories, the shaft centerline orbit, phase portrait the Poincaré maps and the frequency spectrums of the system are acquired by the numerical integral method in some typical parameter regons thereby providing the theoretical base for controlling the chaotic motion and designing this system.
