An analysis of rotor-stator interaction

Abstract

The aim of this paper is to investigate the influence of rotor-stator interaction on the dynamic behaviour of a rotor-bearing system. First the model of a SDOF system with two stop-ends is established. The analytical solution permits testing the stability and the robustness of the penalty contact law combined with two numerical schemes. Second, a three-disk rotor in bending equipped with two bearings is subject to a disk-stator contact. The two numerical algorithms analytically validated are again used and associated to four contact models: three types of smooth penalty methods and the Lagrange multiplier method. Spectrograms of time history responses are presented and permits analysing the spectral evolution of the rotor behaviour.
