Shaft with Non Central Discation could be confined to plane motion of the disc. Now consider the three models shown in Fig. 4.1, with either a noncentral or an outboard disc. Besides 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

The Short and the Long Rotorf motion quoted in Chap. 4, equations (4.8) and (4.47) are valid, however, for arbitrary values of .. and .. that is for shafts having a thick disc or a long stiff rotor body, as shown for example in Fig. 5.1. The vibrational behaviour of such a model will be investigated in the present chapter.

Oil-Film Bearingsc bearings are also increasingly being used. The bearings influence the rotor vibrations to a greater or less degree by their dynamic properties in comparison to those of the rotor and the remaining components of the assembly. This influence originates essentially from the ratio of the rotor stiffne

Rotors with Oil-film Bearingsly, an oil-film bearing can broadly be described as a spring-damper element, with the special property that the displacement and the force in general do not occur in the same direction. In comparison with rotors with rigid bearings, a rotor on oil-film bearings thus has different natural frequencies
