Non-Linear Hysteretic Instability in Rotating Machinery

The destabilizing influence of the shaft hysteresis on the supercritical whirl of rotating machines can be efficiently counterbalanced by proper external dissipative sources in the supports and/or anisotropic suspension systems. The hysteretic effect may be treated either by dry or viscous models, obtaining different but somehow similar results in the hypothesis of small dissipation levels. Thus, the linear viscous assumption is often accepted as a crude approximation for a straightforward analysis of the whirling instability. Nevertheless, the internal friction should be regarded most likely as non-linear and could be approximated for example by Coulombian models, taking thus into account also the releasing effect of some shrink-fit coupling present in the mechanical assembly.
