Original Abstract

Dynamics of rotating systems involves behaviour and diagnostics of rotating structures. When hydrodynamic journal bearings are used to support a rotor a rotor-bearing system becomes a complex dynamic system that may exhibit serious fluid film instabilities. The understanding of the behaviour of a fluid film bearing closely before, during and after the rotor instability origin and growth is the main motivation for a complex research of local and global dynamics of the rotor-bearing system. Deep knowledge of relations between local fluid film dynamics and dynamic response of rotating systems during instabilities can help to improve the design of many modern rotating machines.
