An application of operational modal analysis in modal filtering
Journal of Physics: Conference Series, 2011 Modal filtration in the field of damage detection has many advantages, including: its autonomous operation (without the interaction of qualified staff), low computational cost and low sensitivity to changes in external conditions. However, the main drawback of this group of damage detection methods is its limited applicability to operational data.

Modal Analysis Using Operating Modal Identification Method
Chinese Journal of Aeronautics, 2004 AbstractSometimes it is very difficult for some large scale operating structures to measure the input forces. Modal parameters must be estimated on response only. A poly-reference time domain operating modal identification complex exponential method is presented since cross-correlation functions have the same form as impulse response functions.

Transmissibility-Based Operational Modal Analysis: Enhanced Stabilisation Diagrams
Shock and Vibration, 2012 Recently it has been shown that also transmissibilities can be used to identify the modal parameters. This approach has several advantages: because of the deterministic character of the transmissibility functions, the estimated parameters are more ...

Operational Modal Analysis-Based Control of Cutting Modes in Turning
Журнал інженерних наукTurning, like any cutting process, is performed in a closed machining system and is always accompanied by chatter. Increasing cutting speed to improve productivity was constrained by increased vibration amplitude, resulting in negative outcomes.
