In this paper the results of the application of Operational Modal Analysis (OMA) techniques to rotating systems are shown. The system in study is a rotor-blade system, having time-varying parameters in the equations of motion when subject to rotation. The aim of this study is to show the results of the application of linear time invariant (LTI) OMA techniques to these kinds of systems, both numerically and experimentally, verifying the possibility of identifying both basis and parametric resonances.

Abstract
In this paper the results of the application of Operational Modal Analysis (OMA) techniques to rotating systems are shown. The system in study is a rotor-blade system, having time-varying parameters in the equations of motion when subject to rotation. The aim of this study is to show the results of the application of linear time invariant (LTI) OMA techniques to these kinds of systems, both numerically and experimentally, verifying the possibility of identifying both basis and parametric resonances.| File | Dimensione | Formato | |
