Abstract:This paper presents results obtained within the scope of a collaboration between the ``Laboratoire de Mécanique et d'Acoustique'' (Marseille, France), the ``Laboratoire de Mécanique des Fluides et d'Acoustique'' of the Ecole Centrale (Lyon, France) and the ``Laboratoire de Vibrations et d'Acoustique'' of the Institut National des Sciences Appliquées (Lyon, France). The main aspect of this collaboration is to establish a comparison between a measured and a model vibro-acoustics response of a thin cylindrical pipe excited by a turbulent internal flow. After a brief review of the literature, a model of the response of the shell, based on a matched asymptotic expansion, is given. Some numerical results are also given. The spectral density of the acceleration of the shell is compared with experimental results.
