Abstract

The improvement of the dynamic behaviour of an elastic rotor which is supported by journal bearings represents an ongoing field of research, whereby various modifications of the corresponding bearings and their geometry have been proposed in literature. In order to suppress or at least to decrease unwanted oscillations due to negative effects of instability phenomena of the ’oil‐whirl’‐ and/or ’oil‐whip’‐type, a two‐lobe bearing with an active geometry variation is suggested as an alternative approach. A systematic investigation of the dynamic behaviour of a Jeffcott rotor, which is supported by the mentioned bearing type, is performed by means of the associated spectral system.
