The dynamics of an unbalanced rigid rotor on two-lobe journal bearings is studied in numerical way. Radial dissymmetry of the bearing shape makes the angular orientation one of the main parameters of the analysis.

Abstract

The dynamics of an unbalanced rigid rotor on two-lobe journal bearings is studied in numerical way. Radial dissymmetry of the bearing shape makes the angular orientation one of the main parameters of the analysis. Further parameters are the amplitude of the wave profile, the static unbalance and the speed. Continuation method highlights the dependence of the synchronous response on the parameters. It also allows a tracking of the synchronous motion in a simulated run-up of the rotor.
