Thus, we shall consider a few examples and report results from further calculations. The essential vibration behaviour of the rotors of turbo machines will thus be characterized.

Shaft with Non Central Discsides the displacement of the disc, its rotation around a radial axis must also be considered. As a result its moment of inertia and gyroscopic effect are called into play. The theory of such a model has been given in many publications, for example [27],..., [31].

Such experience, however, has not been acquired for extensive models, such as, for example, the rotor-foundation model discussed in Part III. As an alternative the finite element method has proved to be very useful and will be applied in the following.
