Modal Analysis of a Vibroacoustic Cabin 2008-36-0586

The presence of an acoustic medium influences the dynamic behavior of the structure and vice versa, that is, the structural vibration is influenced by the pressure variation and the acoustic waves are sensible to the variation of displacement of the structure. In this work, one cabin is modeled using beam and plates elements for the structure and solid elements for the fluid domain. The obtained coupled modes are different when the coupling is not considered.
