Principles of Balancing and of Balancing Machines,s are described. Plane separation and the need for Wattmeter filtering are discussed in relation to balancing requirements and signal conditioning. Larger rotor facilities and automated production facilities are described.

Case Histories in Balancing of High Speed Rotors,use was rotor unbalance and/or unsuitable rotor dynamic conditions. In each instance, a diagnostic phase preceded the eventual corrections made to the system. These cases demonstrate both the diagnostic techniques used, and the successful corrections made.

Seal Properties,seal effects, theoretical as well as experimental studies are important in the actual research of rotordynamics. In this chapter a theoretical model and an identification procedure are presented to determine the dynamic coefficients of seals by calculation and measurements as well. The identified pa

Interaction between a Rotor System and Its Foundation, Structures and soil are coupled by means of a substructure technique. The substructure behaviour of soil is treated for rigid and flexible foundation slabs of arbitrary shape by superposition of semianalytical solutions of viscoelastic halfspace field equations. The interaction between a single tur

Torsional Systems: Vibration Response by Means of Modal Analysis,nsients. To solve the torsional vibration problem the turbogenerator shaft is modelled by the finite element method. The equations of motion are solved for the transient vibrations with the modal analysis technique — ‘Time-History-Method’. If the designer is interested in an approximation for the ma
