Abstract
AbstractIn fluid‐filled rotors self‐excited vibrations occur induced by a surface wave of the fluid. A characteristic property is the instability over the full range of angular velocity above the Eigenfrequency of the system. A possible explanation is the occurrence of synchronization effects between fluid and rotor.The behaviour of rotors partly filled with fluid was mostly studied under the aspect of stability in steady‐state conditions. For non‐steady‐state investigations, discrete models with reduced number of degrees of freedom and reasonable ability to model the system behaviour are desirable due to the complexity of fluid modelling.This paper analyses a simple minimal model and shows synchronization effects between fluid and rotor model.
