Nonlinear model of vibration in rotor-bearings system. Part II. Calculation results
JAN KICIŃSKI
Abstract
The results of simulation research related to the description of the most striking and not yet fully explained phenomena occurring in the oil film of slide bearings, namely, the oil whirls and whips have been presented. The calculations were made on the example of a laboratory rotor, based upon two supports with flexible external fixing of the bearing shells, and a 200 MW steam turbine rotor as well. The respective initial phases of the oil vibrations development have been determined in details and an attempt has been made to classify the orbits and to find out a practical diagnostic discriminant.
