Part I—Theoretical Model for a Synchronous Thermal Instability Operating in Overhung Rotors
Atheoretical model has been developed for a synchronous thermal instability that is caused by differential viscous shearing in bearings of overhung rotors. This model employs an unbalance threshold criterion for instability instead of utilizing a traditional frequency-domain stability analysis. The...

| Summary: | Atheoretical model has been developed for a synchronous
thermal instability that is caused by differential viscous
shearing in bearings of overhung rotors. This model employs
an unbalance threshold criterion for instability instead
of utilizing a traditional frequency-domain stability analysis.
The current model will be used to investigate several case
studies for both plain and tilting pad journal bearing rotors
in the second part of this article. |
