Abstract
This study aims at developing an experimental method for characterizing the vibro-acoustic behavior of panels excited by random pressure fields. Although the method would be theoretically applicable to any stationary in time and spatially homogeneous random process, and for points belonging to the acoustic medium or to the panel, the turbulent boundary layer excitation is considered in this study while considering the vibration response exclusively. The interest of industrials toward this excitation has grown over the years. The main reasons being that the associated test means (i.e., wind tunnel or in situ measurements) are hard to control and very expensive. They are also subjected to large variabilities between laboratories, which makes it hard to attest the validity of the measuring technique. The proposed method allows to experimentally characterize a panel under such an excitation by separating the contribution of the excitation from the vibration behavior of the panel.
