By comparison with other methods with the same feature, thenew method has the advantage that it does not require the measurement of a completerow of the frequency response function (FRF) matrix.The new method is based on the modelling of rotating machines as structural assembliesof rotating and non-rotating components. The method accounts for the effects of gyroscopic and other forces related torotation, which are associated with the asymmetry of the damping and stiffness matricesof rotating machinery.
