| description | This paper presents a methodology and some results on the dynamic stability of an elastic
rotating system consisting of one- and twodimensional members. These parts may contain
different kinds of unsymmetries: either from mass- or stiffness imperfections or from anisotropic
especially hydrodynamic bearings. The equations of motion are formulated using
virtual work and an Finite Element approach. Special attention is paid to a kinematically
consistent coupling of the elastic shell and disc. The eigenvalue extraction is based upon the
method of Lanczos including a modal reduction and a correction process in order to ensure
true diagonal system matrices. Some typical results for a shaft-disc-shell system with different
bearings and imperfections are presented in detail. |
