2011 SEP 28 - (VerticalNews.com) -- "Operational Modal Analysis (OMA) extractsrnmodal parameters of a structure using their output response, during operation in general. OMA,rnwhen applied to mechanical engineering structures is often faced with the problem of harmonicsrnpresent in the output response, and can cause erroneous modal extraction," scientists writing inrnthe journal Mechanical Systems and Signal Processing report.
