Résumé

La propagation d'onde acoustique de fil-cassent (wire break) les événements relatifs (WRE) dans des pipes remplies de fluide de cylindre de béton contraint d'avance (PCCP) sont d'intérêt pour la détection non destructive de pipe. Le modèle mathématique développé est basé sur l'équation du mouvement de Navier pour la propagation d'onde acoustique. La loi de Newton du mouvement dans l'équilibre est employée pour modeler l'interaction de fluide-structure. L'analyse structurale de l'effet acoustique de pression sur la structure de pipe est expliquée par le principe du travail virtuel. Pour comprendre les caractéristiques de la vibration de WRE et l'impact du chemin sur la vibration signale, le comportement de dispersion de la propagation des ondes est analysé en utilisant divers profils de pipe. On l'observe que la vitesse des vagues voyageant dans le fluide entouré par le profil fini de pipe de rigidité est inférieure que la vitesse réelle des ondes acoustiques du signal de WRE en fluide illimité ou fluide entouré par milieu infini de rigidité. Le logiciel est employé pour simuler les resultants.
