Conference proceedings: An overview of nonlinear vibration phenomena in hydrodynamic journal bearings
Original language description
Proceedings of XXX Conference Vibrations in Physical Systems VIBSYS 2022 in Poznan (Poland). Hydrodynamic journal bearings are widely used in the field of rotational machinery for their low friction behaviour, low wear and vibration-damping capabilities. However, when hydrodynamic journal bearings are used to support a rotor, the whole system becomes a complex dynamic system that may exhibit fluid-induced instabilities. Understanding of behaviour of the journal bearing closely before, during and after the instability origin and growth is the main motivation for complex research of local and global dynamics of rotor-bearing systems. Fluid film bearing related characteristics such as self-excited oscillations, thermo-elastic expansion, and fluid inertia are known to induce nonlinear response states of the rotor system such as sub-synchronous, quasiperiodic, aperiodic, end even chaotic motion.
