Experimental modal analysis tutorial

Résumé fourni par la source

This 2-h session will provide an overview of experimental modal analysis (EMA) emphasizing the use of frequency response functions applied to aerospace engineering applications. After a brief overview of EMA concepts using simple lumped parameter models, this presentation will provide an in-depth review of the steps required in a typical aerospace level modal survey test including test planning, test setup, data collection, signal processing, mode shape extraction, and validation. Finally, recent advances in modal survey testing using acoustic sources as exciters will be discussed.
