Abstract
Hysteretic whirling is a self-excited instability usually associated with built-up rotors in lightly damped bearings, in which the rotor whirl amplitude increases with time. It is independent of the state of balance of the rotor and it commences at speeds above a certain threshold speed. It most frequently arises from rubbing between assemblies of shrink- or pressfitted rotor components, e.g., compressor wheels on a central shaft. It can also arise from internal hysteresis of the shaft material. As many modern rotors are complex assemblies of components, the conditions under which assembly or material hysteresis may give rise to unstable whirling are of great interest (see figure 1).
