Remaining service life prediction based on gray model and empirical Bayesian with applications to compressors and pumps
Li, Xiaochuan; Mba, David; Okoroigwe, Edmund; Lin, Tianran (Article)In this study, a three-step remaining service life (RSL) prediction method, which involves feature extraction, feature selection, and fusion and prognostics, is proposed for large-scale rotatingmachinery in the presence ... -
A study on helicopter main gearbox planetary bearing fault diagnosis
Zhou, Linghao; Duan, Fang; Elasha, Faris; Corsar, Micheal; Mba, David (Article)The condition monitoring of helicopter main gearbox (MGB) is crucial for operation safety, flight airworthiness and maintenance scheduling. Currently, the helicopter health and usage monitoring system, HUMS, is installed ... -
Using Frequency Domain Analysis Techniques for Diagnosis of Planetary Bearing Defect in a CH-46E Helicopter Aft Gearbox
Zhou, L.; Ojolo, S.; Wang, W.; Mba, David; Duan, F. (Article)Condition monitoring for helicopters has always been one of the most critical technologies to guarantee the integrity of the rotorcrafts, enhance operational and personnel safety, and reduce the overall maintenance costs. ... -
Valve Failure Prognostics In Reciprocating Compressors Utilizing Temperature Measurements, PCA-based Data Fusion And Probabilistic Algorithms
In the present paper, temperature measurements are utilized to develop health indicators based on principal component analysis towards the probabilistic estimation of the Remaining Useful Life (RUL) of reciprocating ...
