Thermal Bending of the Rotor Due to Rotor-to-Stator Rub

open access: yesInternational Journal of Rotating Machinery, 2000
The rotor thermal bending due to the rotor-to-stator rubbing can lead to one of three types of observed rotor lateral motion: (1) spiral with increasing amplitude, (2) oscillating between rub]no-rub conditions, and (3) asymptotical approach to the rotor ...
