The boundary element method for linear acoustic systemsde Leon, Simon January 2008 (has links)
A technique based on the transient boundary element method for the numerical simulation of three-dimensional linear acoustic systems is presented. Using surface meshes generated by \texttt{Distmesh} \cite{persson:2004}, pressure is extracted from points within the enclosed volume of the mesh by integration of retarded potentials across the boundary. As a result, mesh junction calculations and topology-related inaccuracies within the volume are avoided. For simulations of struck instruments, membrane motion is modeled using two-dimensional digital waveguide techniques adapted for an unstructured triangular topology and coupled with the internal pressure field. The method is also used to extract response characteristics of an open, unflanged pipe and the results are compared to a one-dimensional waveguide model. Finally, possible future work using the freely available software developed for this project is discussed. / Une technique de simulation numérique des systèmes acoustiques linéaires tridimensionnels basée sur la méthode d'éléments de frontière transitoires est présentée. La librairie Matlab \texttt{Distmesh} \cite{persson:2004} a été employée pour générer des maillages représentant la surface de tels objets. La pression en tout point du volume est obtenue par intégration des potentiels tout au long du maillage. Ainsi les calculs aux noeuds du maillage de même que les inexactitudes de topologies connexes dans le volume sont évités. Dans le cadre de la simulation d'instruments percussifs, le mouvement de la membrane est modélisé au moyen de guides d'ondes bidimensionnels particulièrement bien adaptés à une topologie triangulaire non-structurée. L'effet de couplage dû aux pressions internes est aussi pris en compte. D'autre part, la réponse caractéristique d'un tube droit, ouvert aux deux bouts obtenue par cette méthode est comparée aux résultats d'une méthode basée sur les guides d'ondes monodimensionnels. Enfin, de possibles applications du logiciel developpé pendant ce projet (et librement disponible) sont présentées.
