Повний текст джерелаStrukturburet ljud kan färdas flera olika vägar från ett kontor till ett annat och att ljudisolera en specifik vägg kan vara svårt då alla byggnadselement är ihopkopplade och skapar ett kopplat system. Den nuvarande metoden ingenjörer använder för att undersöka transmissionsvägar mellan rum är att skapa modeller i datorprogram där antaganden att byggnadselementen är fast inspända eller fritt upplagda är gjorda. Standardiserade mätmetoder använder sig av en stor mängd mätpunkter på båda sidor om knutpunkterna och excitationer över stora ytor. Den här studien avser att undersöka möjligheten att erhålla värdefull information med ett fåtal mätpunkter i en fältmätning genom att jämföra den samlade mätdatan med en analytisk modell och en FEM modell. Fältmätningen består av excitation med en impulshammare i två excitationspunkter och tre accelerometrar på vardera sida om knutpunkterna och båda sidor om skiljeväggen. Mätningen utfördes i en kontorsbyggnad, utan någon information om strukturen förutom längd, bredd och tjocklek på byggnadselementen.Reduktionen över knutpunkterna varierade i frekvens och inga generella slutsatser kunde göras angående transmissionsvägar. Resultaten visade hög reduktion i vibrationsskillnad över knutpunkterna i låga frekvenser vilket minskade med ökad frekvens. Mätningsresultaten stämde överens med den analytiska modellen i låga frekvenser, med avseende på att reduktionen över knutpunkter med lätt skiljevägg är hög i låga frekvenser och avtar med ökad frekvens. Resultaten över knutpunkterna var beroende på val av excitationspunkt vilket indikerar att mätresultaten innehåller flankerande transmissioner och att det är ett komplext kopplat system.

Повний текст джерелаExhaust noise has a significant impact on acoustic comfort and the sound identity of a vehicle brand. The present study focuses on the: “Description and quantification of the sound transmission from the exhaust outlet into the interior of a vehicle”. Physically the noise propagation from the exhaust pipe to the cabin consists of three steps: The sound waves propagate through the air from the exhaust outlet to the external skin of the vehicle (1); the external skin vibrates and transmits its vibration to the internal skin (2); the internal skin radiates sound in the passengers’ cabin (3). The Patch Transfer Functions method, which is based on the framework of dynamic substructuring, allows for the consideration of this complex problem as simpler subproblems that consist of subsystem interactions. Yet the application of the method to a full vehicle requires addressing the problem: “Characterization of Patch Transfer Functions of a subsystem by means of measurement on a coupled system”. This dissertation presents an original inverse method for the measurement of Patch Transfer Functions. In industrial structures, this in-situ characterization is generally the only possible measurement method. Yet, due to the ill posed nature of the problem, the inversion process is difficult. An original regularization method is proposed. The method is tested through numerical simulations, and is validated with an experimental setup

Повний текст джерелаMy PhD work has focused on understanding physical phenomena related to speech production in healthy and pathological conditions. Some pathologies affect the structure of the vocal folds which could lead to a more or less substantial alteration of their vibrations. Part of this work is experimental modeling of speech production applied to pathologies, with the development of a self-oscillating vocal fold replica. This replica is made of water-filled latex, such as have already been developed at Gipsa-lab, but it allows a larger independence within its control parameters and it can be used to reproduce pathological conditions. A particular interest is brought to mechanical characterization of these vibrating structures. This characterization is of primary importance when it comes to repeatability and reproducibility of measurements, as for the analysis of experimental results with aeroacoustic coupling and the validation and improvements of corresponding numerical models.Simulations of the vocal fold vibrating behavior based on the finite element method have been developed. The model uses a formulation of the hydro-elastic coupling between the latex and the water which the replica is made of. It also offers the possibility to take into account the large deformations and the prestress within the latex induced by water pressure. Another numerical approach is made using a theoretical laryngeal flow model coupled with a distributed mass-spring model and a set of resonators. Calculations of the dynamical system stability offer the possibility for comparisons with the experimental setup through a finite set of parameters. This model is adapted to simulate pathological conditions such as asymmetries and the presence of growths (cysts, polyps). Finally, an optimization calculation of this model on an experimental reference configuration of the replica allows us to compare the calculations with the measurements on this replica with the presence of a polyp

Повний текст джерелаprésents aux limites des structures (plaques ou poutres) à partir de déplacements mesurés. Les expressions analytiques de ces
efforts contiennent des termes proportionnels aux dérivées spatiales du déplacement. L'approximation de ces dérivées aux
limites d'une structure est problématique car ces dernières sont très sensibles aux erreurs de mesure et les méthodes classiques
de calcul (différences finies, méthodes modales, transformée de Fourier spatiales, ...) et de régularisation (filtrage en nombre
d'onde, troncature modale) pour les obtenir ne sont pas adaptées pour une identification aux limites d'un domaine spatial.
Dans ce travail, une approche mathématique est proposée. Il s'agit de calculer les efforts aux limites, sans
utiliser directement leurs expressions analytiques qui contiennent les dérivées spatiales. La méthode est basée sur un calcul
intégral de l'équation de mouvement de la structure considérée, multipliée par une fonction test, qui vérifie des conditions aux
limites particulières. Ces conditions permettent d'extraire, lors du développement du calcul, les efforts recherchés à la limite du
domaine (efforts tranchant ou moment fléchissant).
La technique est développée dans les cas mono dimensionnel (poutre) et bidimensionnel (plaque). Des
simulations numériques illustrent la méthode, testent la robustesse de la méthode, les effets de différent bruits de mesure sur
l'identification, et établissent les limites spatiales et fréquentielles de l'approche. Des expérimentations ont été menées,
montrant la faisabilité de la méthode d'identification en utilisant des mesures réelles.

Повний текст джерелаFondée sur une approche modale et un formalisme vectoriel, elle s'appuie sur l'exploitation d'une matrice de couplage adimensionnelle qui décrit les échanges entre les deux plaques. Cette matrice admet autant de valeurs propres de couplage (quantités totalement déterministes) que de ressorts entre les plaques. Ces valeurs propres sont représentatives de la force du couplage tandis que les vecteurs propres indiquent les chemins modaux de transmissions. L'utilisation de ces quantités propres permet de reconstruire l'état vibratoire des plaques après couplage connaissant leur état avant couplage (en configuration découplée bloquée).
Une méthode simplifiée est développée dans le cas du couplage multiple. Le chemin de transmission dominant est identifié par l'examen et le tri des valeurs propres de couplage. Le fait de ne garder que la contribution correspondant à ce chemin modal dominant donne d'excellents résultats, l'erreur maximum par rapport à la solution de référence atteignant 3 dB aux plus hautes fréquences.
L'application expérimentale de cette méthodologie est possible puisque les valeurs propres de couplage sont mesurables. La méthode s'apparente à une approche de type mobilité, à la différence près que les grandeurs à mesurer sont en configuration découplée bloquée, ce qui permet d'éviter les fréquences singulières inhérentes à l'approche par mobilité classique. Dans des conditions de couplage multiple, l'application de la méthode simplifiée confirme la qualités des résultats obtenus précédemment de façon numérique.
