Abstract:In order to optimise the vibro-acoustic behaviour of panel-like structures in a more systematic way, accurate structural models are needed. However, at the frequencies of relevance to the vibro-acoustic problem, the mode shapes are very complex, requiring a high spatial resolution in the measurement procedure.The large number of required transducers and their mass loading effects limit the applicability of accelerometer testing.In recent years, optical measurement methods have been proposed.
