La détection d'impacts est une préoccupation majeure pour suivre l'intégrité d'une structure évoluant dans un environnement comportant des risques de collision. Ce travail consiste à développer une méthode d’identification d'impact applicable à une structure composite de grandes dimensions qui soit à la fois robuste, peu coûteuse en temps de calcul, et qui nécessite peu de capteurs. Dans un premier temps, la démarche a été de décrire l'image du point d'impact dans la réponse vibratoire par un vecteur de participations modales. L'idée a ensuite été d'introduire l'hypothèse d'existence d'une famille de modes discriminants permettant d'établir le lien bijectif entre les participations modales et le point d'impact. Une procédure d'estimation de...
