title = "A MIMO modal analysis method with coherent excitations and its application to boundary reactions",
abstract = "Standard experimental modal analysis is performed with free boundary conditions and one or more incoherent excitation(s). This permits the direct measurement of the structure's receptance matrix elements and as such allows the direct identification of the system poles. Operating structures however can not be identified in this way, as the operating forces ask for a suspension of the system to its environment. A shaker excitation to the structure will therefore result in interface forces between the system and its environment. If one would measure these forces, they would be coherent to the shaker excitation and could be seen as a force feedback on the system. In this article we therefore present a MIMO modal analysis method with coherent excitations. As the excitations are coherent to each other, a direct measurement of the receptance FRFs is not possible. The method presented here therefore determines the modal parameters based on a nonlinear solution of the pole/residue model.",
