Influence of different parameters
A gyroscopic system, for example an elastically supported gyro, passes critical speeds when the rotor runs up or down. The vibrations of the rotor and the bearings become large and are caused by the unavoidable unbalances of the rotor. Investigations of one-degree-of freedom vibrators have shown  that the resonance amplitude can be reduced by rapidly running through resonance. Now it is of interest if and to what extent this result is valid for systems with several degrees of freedom. As an actual example the elastically supported gyro (Chapt. 4) may serve for this investigation but most of the results can be generalized.
