| description | This paper deals with an experimental study of a dual rotor test rig. This
machine, which was developed and built at the Laboratoire de
Tribologie et Dynamique des Systèmes, Ecole Centrale de Lyon, will
be first presented. It is composed of two coaxial shafts that are connected by
an intershaft bearing and rotate independently, each one driven by its own
motor. Their lateral vibrations and whirling motion are coupled by the intershaft
bearing. The experimental tests consisting in run-ups and the associated
measured unbalance response of the dual rotor will be investigated. The
influence of the rotation of each rotor on the critical speeds and the associated
amplitudes will be discussed. Moreover, this paper presents a numerical model
of the dual rotor. Correlations between the experimental and numerical tests will
be investigated. The objective is to be able to predict phenomena observed in
experiments, starting from a rather fine numerical model. |
