THE APPLICATION OF FLOQUET METHODS IN THE ANALYSES OF ROTORDYNAMIC SYSTEMS

Floquet theory is considered as a possible methodology for quantifying stability in rotordynamic systems. The method proposed here allows for kinematic data collected from experimental and/or simulation results and captured at specific instants in time to be efficiently analyzed. This approach makes...

More Information
Summary:Floquet theory is considered as a possible methodology for quantifying stability in rotordynamic systems. The method proposed here allows for kinematic data collected from experimental and/or simulation results and captured at specific instants in time to be efficiently analyzed. This approach makes it possible to accommodate complex dynamics under various configurations. The application of the proposed methodology to a rotor system is described. (AIAA)
