Journal ArticleDOI
Cyclostationary modelling of rotating machine vibration signals
TL;DR: In this article, it is shown that vibration signals exhibit cyclostationarity if and only if the random speed fluctuation of the machine is periodic, stationary or cyclostatary.
Journal ArticleDOI
Use of the acceleration signal of a gearbox in order to perform angular resampling (with limited speed fluctuation)
TL;DR: In this article, the authors propose a method to resample the signal against the angle by using the acceleration signal of a gearbox, where the gear tooth pairs produce contact shocks during rotation and these shocks are processed in order to retrieve the position of the gear against the time.
Journal ArticleDOI
Dynamic modelling of spur gear pair and application of empirical mode decomposition-based statistical analysis for early detection of localized tooth defect
TL;DR: In this paper, a 6-degree-of-freedom gear dynamic model including localized tooth defect has been developed, which consists of a spur gear pair, two shafts, two inertias representing load and prime mover and bearings.
Journal ArticleDOI
Model-based diagnosis of large diesel engines based on angular speed variations of the crankshaft
TL;DR: In this paper, a 20-cylinder diesel engine with crankshaft torsional modes in the low frequency range is modeled with a phenomenological model and an automated diagnosis based on an artificially intelligent system is proposed.
Journal ArticleDOI
Cyclostationarity approach for monitoring chatter and tool wear in high speed milling
TL;DR: In this article, a cyclostationary method was used to process the vibrations signals acquired from high-speed milling to detect chatter and tool wear in high speed machining.
