- Leontiev M.K. , Degtiarev S.A. Vibration analysis of electric generator rotor supported on journal bearings
The present paper shows the calculation results of the separate generator “BRUSH” being the part of the system “the power turbine, the transmission and the generator”, with the aim of its stability thresholds determination. Several variant investigations are carried out. The task of the first research is to determine its stability thresholds on plain journal bearings in order to check two methodologies of determination of the rotor generator stability boundaries. The task of the second research is to determine the stability thresholds of the rotor on the elliptical journal bearings. Modeling and linear analysis of the generator rotor system was carried out previously [1].
