abstract = "Dynamic analysis of a structure plays an important role during its design phase. The dynamic analysis usually consists of both numerical simulations of a structural model as well as experimental modal analysis for model validation. For model validation, both numerical simulations and modal testing are often performed with the assumption of free boundary conditions. In reality, this can only be approximated however because of the required structural supports in the experiment. The stiffness and damping of the supports has an influence on the measurements and subsequently on the extracted modal frequencies and damping. Depending on the type of structure or analysis, these errors might not be admissible. This article introduces a MIMO modal analysis method which eliminates the suspension influences and therefore allows the determination of the free-free structural properties. The presented method determines the modal parameters based on a nonlinear solution to the constrained pole-residue model.",
