โœฆ Synopsis

A finite element model is presented for a flexible, non-axisymmetric shaft-rotor system supported in distributed bearings. The stability of this model is analyzed over a normal rotation speed range and the results are compared with analytical and numerical studies carried out on rigid and simpler flexible models. The same types of regions of instabilities are found for the finite element, flexible shaft-rotor model, and the role of shear deflection is particularly significant in one of the mechanisms.

A finite element model of a rotor-bearing system with non-axisymmetric stiffness and mass properties was analyzed in a previous study. In this paper the model is extended to include the effects of external damping due to symmetrical tilting-pad bearings. The same instability mechanisms, due to the l
