Abstract

Procédé permettant de stocker des données concernant l'histoire du fonctionnement d'une turbomachine. Il consiste à comparer la température de fonctionnement de la turbomachine avec une température de transition TTF, à compter des excursions de contrainte survenant en dessous de la température de transition, et à compter des excursions de contrainte survenant au-dessus de la température de transition. Application aux arbres alésés de rotor de turbomachine.
