Operational Modal Analysis Challenges in Case of Rotating Machines KU Leuven
Operational Modal Analysis (OMA) is widely employed and became an industrial standard technique for identifying the modal parameters (i.e. resonance frequencies, damping ratios and mode shapes) of mechanical structures. Its main applications are in the automotive, aerospace, civil engineering domains and many others. The advantage, if compared with Experimental Modal Analysis (EMA), is that it is not necessary to stop the machine, but its ...
