Abstract
In this paper, we focus on the interaction fluid-structure and specifically the vibro-acoustic problem. For the coupling fluid structure finite elements 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 matrixes size. A numerical vibratory study is leaded on a structure 3D wing of aircraft in air taking the acoustic aspect into account. In this context, we focused very specifically on a deterministic and stochastic analysis through numerical simulations in 3D dynamic fluid-structure interaction problems.
