An Acoustic Resonance Study of Complex Three-Dimensional Cavities by a Particular Integral Method

Résumé

In this paper, a three-dimensional boundary element method developed to evaluate the acoustic resonance of complex cavity is presented. The formulation is based on a particular integral method. Neumann or mixed boundary conditions are considered. Some numerical tests are carried out and results compared to classic models. General agreement is observed. A practical eigenfrequency analysis is realized by applying the model to a complex car cabin. The Arnoldi method is used to achieve the eigenfrequencies. A good numerical behaviour is observed and its implementation and use are quite easy.
