The proposed solution consists in generalizing the first-order cyclostationary class to the more general first-order cyclo-non-stationary class which enfolds speed-varying deterministic signals.

In this case, these techniques fail in analyzing the produced vibration signals. Information available as an option.

The principal goal of this thesis is to partially fill in this gap on the basis of a theoretical formalization of the subject and a systematic development of new dedicated signal processing tools.

Vibration-based condition monitoring of rotating machines in nonstationary regime. This service is produced by Tournanye. Three different but complementary visions have been proposed to deal with the changes induced by the nonstationarity of the operating speed.


In this work, the nonstationarity of the regime is confined to that of the speed— i.

Unfortunately, most monitored machines used in the industry operate under nonstationary regimes in order to fulfill the task for which they have been designed. Help with expert advice. In the last decades, vibration-based condition monitoring of rotating machine has gained special interest providing an efficient aid for maintenance in the industry.

But these works remain limited, dispersed and generally not supported by theoretical frameworks. Click on one of the icons to share the company.

The second type includes random periodically-correlated waveforms known as second-order cyclostationary. Friday, September 23, – 4: Tournnte Abboud 1 AuthorId: We have elaborated this strategy by distinguishing two types of signatures.
