| Summary: | as function of the rotor system parameters such as the load, bearing can lose stability through either a subcritical or a conducted on short and long fluid film bearings with a simple cycle was observed, while in the subcritical bifurcation film bearings in predicting these phenomena are discussed. flexible unbalanced rotor had a lower threshold speed of instability. The limitations of the linear theory of fluid journal bearing became unstable below the rotor threshold of a subcritical bifurcation, it was also observed that the of operation ( region where the rotor is stable below the on the obtained experimental results. Experiments were also performed to analyze the effects of imbalance of the rotor on single disk rotor. The behavior of the journal was analyzed speed and imbalance mass. It was verified that the journal speed of instability, following a small perturbation applied supercritical bifurcation. In the supercritical bifurcation, the expected gradual increase in the amplitude of the limit The thesis presents the results of the experiments that were the threshold speed of instability. It was observed that the there was a sudden jump to a large limit cycle. In the case threshold speed of instability) for the journal bearing based to the rotor. Demarcations were made for the stable regions |
