Lobjectif principal de ltude est de dvelopper un logiciel danalyse modale automatique qui fonctionne sur une machine en opration partir de la connaissance des rponses vibratoires seulement. Lapplication envisage est lanalyse modale des turbines hydrauliques immerges et excites par un coulement turbulent, en vue de dterminer les masses et amortissement ajouts, en vue de dterminer les contraintes dynamiques dues lamplification du systme vibratoire. Cette thse prsente donc une recherche sur lanalyse modale des machines ou structures en opration, par utilisation dun modle autorgressif. Comme ce type de systme mcanique peut tre instationnaire, avec des paramtres physiques variant dans le temps, une nouvelle mthode de suivi dans le temps et de surveillance en ligne des paramtres modaux a t dveloppe et introduite dans un logiciel de suivi des frquences et amortissement de systmes instationnaires en opration.
