L'objectif de ce travail est de proposer deux nouveaux indicateurs pour le diagnostic des réducteurs complexes à engrenages. Ces indicateurs sont obtenus à partir du cepstre d'énergie des signaux accélérométriques prélevés sur ces réducteur

International audience; Despite rarely being made explicit, signal models (and assumptions) for gear vibration have been fundamental in the development of both condition monitoring and operational modal analysis techniques. The analysis (for conditio

International audience; The analysis of the squared envelope spectrum (SES) is one among the most used tools for bearing diagnosis. It can easily reveals the characteristic frequencies related to the bearing fault. Actually, the envelope is estimated

International audience; Random sampling was first introduced in 1960’s [1], and then reused in Compressive Sensing in 2004 [2] for having two important advantages: anti-aliasing property and low sampling rate, which decreases the demand of high spe
