Abstract

This paper deals with the long term behaviour of flexible rotordynamic systems, which are supported by nonlinear bearings. A system consisting of a rotor and shaft which is supported by one oil journal bearing is investigated numerically. The shaft is modelled using finite elements and reduced using a Component Mode Synthesis method. Branches of periodic solutions are calculated for three models of the system with an unbalance at the rotor. Also self-excited oscillations are calculated for the three models if no mass unbalance is present. The results show that a mass unbalance can stabilize rotordynamic systems and that the first eigenfrequency of the systems has great influence on the self-excited oscillations
