Rotating shafts are modelled as one dimensional continuum on the basis of the Bernouli-Euler theory, which assumes that the shaft cross section remains a flat plane and is perpendicular to the centerline during vibration. Disks are modelled as three dimensional continuum by means of the finite element method. The presented approach allows the effects of the rotation such as centrifugal and gyroscopic effects to be introduced. The two possible approaches to the coupling of the shaft and disk subsystems are proposed. The elementary numerical example is presented. The results based on the new modelling methodology are compared with the results based on the original methodology using the assumption of a rigid disk.
