Combined use of FRFs and transmissibility functions in an OMAX framework Vrije Universiteit Brussel
During the recent years several new tools have been introduced in the field of Operational Modal Analysis (OMA) such as the transmissibility-based approach and the OMAX concept. Most OMA estimators assume that the ambient forces are random noise sources with a flat amplitude spectrum. The transmissibility-based approach does not require this assumption: it works for almost any kind of ambient forces. The main advantage of the OMAX concept is the ...
