Optimization of perforated plates in interaction with acoustic waves
Original language description
The paper deals with optimization of a perforated plate which interacts with acoustic waves propagating in an inviscid compressible fluid. In general, the aim is to influence the acoustic signal conducted through a waveguide in which the perforated plate is fitted. Nonlocal transmission conditions have been derived by homogenization of a problem describing vibroacoustic fluid-structure interactions in a fictitious layer in which the plate is embedded. The Reissner-Mindlin theory of plates is adopted for periodic perforations designed by arbitrary cylindrical holes For rigid plates, quite general types of perforations can be considered for which homogenized transmission coefficients reveal coupling of the transverse and tangential waves. For both the rigid and the deformable plates, the homogenized model of the vibroacoustic transmission has been derived using the two-scale asymptotic analysis. The design of the holes perforating the plate is parameterized by the B-spline representation of the reference periodic cell generating the transmission layer.
