...Tsuyoshi Inoue; Yukio Ishida; Gao Fei; Hossain Md Zahid In rotating machinery, rubbing occurs between the rotor and the stator, at the seal, between the rotor and the guide and between the rotor and the backup bearing. The backward rub or the partial impact vibration can be avoided by lubricating...

...Anatoly A. Kozhenkov; Rafail S. Deitch This paper presents the modeling procedure for a high-velocity rotor system (RS) combined with sliding bearings. The equations for motion of the RS parts were derived based on the model of a rotating elastic medium. Lubrication layers have been calculated...

... to the introduction of AE operational maps. It is concluded that under an elastohydrodynamic lubrication regime, AE activity can be directly related to the theoretically predicted specific film thickness within the bearing. From Fig. 5 , it was noted that an increase in rotational speed results in an increase...
