| Summary: | The paper discusses Bifurcation Diagrams of rotor stator contact problems and the transition from synchronous whirl towards different asynchronous movement patterns. Bifurcation Diagrams based on Poincaré Maps are presented for the model consisting of a JEFFCOTT rotor and a flexible mounted rigid stator ring. The analysis methods are applied systematically with respect to various motion patterns that have been observed for rotor stator contact in the past. The type of motion is identified using the analysis methods. Also the influence of different parameters on the changes of motion patterns and the transitions that result are described. The unique identification of all motion patterns for rotor stator interaction based on Bifurcation Diagrams is focus of the paper. Further insight on the conditions that lead to the change of motion patterns is given. |
