ON THE STABILITY OF ROTORS IN CYLINDRICAL JOURNAL BEARINGS

Abstract

The regions of stability for plane cylindrical journal bearings are determined analytically. The linear variational equation of motion was employed to obtain the stability regions bounded by families of load-carrying capacity and operating eccentricity curves. The results were applied to the quisi-static equilibrium case for gas lubricated cylindrical journal bearings L/D equals 2. They show that there exists a minimum in the stability curves, a prediction supported by experimental evidence. The results of this work seem to bridge together observation on stability at very small and large clearances. (Author)
