Studies of rotor-stator system subjected to noise excitations

Abstract eng:
In this work, the authors present stochastic averaging studies conducted to examine torsional vibrations of a Jeffcott rotor subjected to continuous stator contact. The rotor drive input includes a deterministic input and white noise. The influence of noise on both forward and backward whirling motions is considered. In the experimental arrangement, noise is introduced through the drive motor signal. The experimental results are presented along with the results of the analytical-numerical studies and discussed.
