The main goal of this thesis is the experimental study of the Morton effect in hydrodynamic bearing for rigid and flexible rotors. The Morton effect is a thermally induced increase of the synchronous vibration phenomenon that appears in journal bearing. The introduction part permits to describe the thermal instabilities with firstly a focus on the Newkirk effect and its mathematical description to understand the philosophy of thermal instabilities. Bibliography study of the Morton effect is fully described (case studies, numerical analyses, experimental analyses). The first experimental analysis is conduct for a rigid rotor on a plain journal bearing. In this configuration, the test rig is detailed, the dynamic characteristics of the bearin...
