Summary
This paper focuses on fluid-structure interaction and specifically the vibroacoustic problem. For the coupling of fluid structure finite element models, the importance of the size reduction becomes obvious because the fluid freedom degrees will be added to those of the structure. A method of condensation will be used to reduce the matrix sizes. A numerical vibratory study is based on a three-dimensional model of a wing of an aircraft in air taking into account the acoustic aspect. In this context, the focus is very specifically on a deterministic and stochastic analysis using numerical simulations in thr-dimensonal dynamic fluid-structure interaction problems.
