Supression of Rotor Instability the bearing radial stiffness or the bending stiffness of the rotor, or both. The second requirement can be met by using a bearing or support type which inherently contains more non-rotating velocity damping. It should be noted that the increase of any damping which rotates with the shaft itself has

Hysteretic Instabilityde 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 ari

etidronate

Fluid Instability independent of rotor unbalance. It occurs as a self-excited whirl motion above a certain threshold speed, and is induced by the action of hydrodynamic forces within the journal bearings. The rotor journals then whirl in a circular or elliptical orbit within the bearing clearance, about the steady-s

Identification of Rotor Parametersate. Therefore the mechanical behaviour of the rotor has to be analysed. Whereas the inertia distribution of the shaft can be determined from its geometry, the stiffness distribution cannot be obtained easily because of jumps in the diameter of the shaft. In modeling the system consisting of a rotor
