Abstract [en]

A method to automatically name structural modes is proposed. It is essentially based on Modal Assurance Criterion (MAC) to pair un-named modes with modes from a reference data base. Each new naming allows feeding the reference data base. A script has been implemented and tested on Rafale and Falcon aircraft simulation data. After operational validations, this method appears to be efficient and reliable. The mode pairing method may be used to track modal evolution of a structure after structural modifications and thereby to predict modal behavior in aero-elastic calculations.
