The rotating system vibration and diagnostics

The condition monitoring, protection and fault diagnostics system is inherent module in the failure prevention technology of modern machines. The paper is dedicated to research of dynamics, condition monitoring, fault diagnosis and modeling of high speed blower rotor failure prognosis. The specificity of the dynamic model comprises dynamics of the tilting-pad journal bearings. The blower rotor vibration displacements were monitored with contact less sensors during nominal load, run up and shout down modes. Hypotheses about physical nature of bearings failure effect are verified by experimental and theoretical research, where dynamical model was designed and simulated.
