Abstract
An insight into the mechanism of oil whirl is obtained by investigating theoretically and experimentally its two main characteristics, frequency and amplitude. It is shown that the ratio of steady oil-whirl vibrational frequency to shaft speed may be predicted qualitatively by a linear treatment and some conclusions of a nonlinear treatment are also given. It is also concluded that oil-whirl amplitude can be restricted by the oil supply pressure. Experiments involving the use of a rigid rotor supported on two fully lubricated 360° journal bearings are described and ratios of steady oil-whirl frequency to shaft speed as low as 0.37 reported.This publication has 6 references indexed in Scilit:
