摘要：

The influence of oil-film turbulence on the parametric excitation instability of a symmetrical unbalanced rotor in short bearings is analysed for different values of Reynolds number. The method of calculating the journal orbit is described together with the method for predicting the synchronous orbit whose stability is to be evaluated. In addition to examples of calculated and predicted orbits, stability maps are given for dimensionless unbalance values equal to 0.2, 0.3 and 0.4 and for the Reynolds numbers of 2500, 5000 and 10000.
