Information available as an option. Frequent updates ensuring high quality data Secure online payment Help with expert advice Dedicated customer service team. In the last decades, vibration-based condition monitoring of rotating machine has gained special dr providing an efficient aid for maintenance in the industry. The first type includes deterministic waveforms tournxnte as first-order cyclostationary. INSA de Lyon, In this case, these techniques fail in analyzing the produced vibration signals.

Description Key figures Executives Activities. Other classifications for some countries NAF Rev. 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. In this aalyse, the nonstationarity of the regime is confined to that of the speed— i.

Many tools have been conceived whose performances have been successfully tested on simulated and real vibration signals.

The data we collect are only those necessary for the proper use of our service. The second type includes random periodically-correlated waveforms known as second-order cyclostationary.

Turnover Information available as an option. Three different but complementary visions have been proposed to deal with the changes induced by the nonstationarity of the operating speed.

This issue, therefore, has occupied the scientific committee in the last decade and some sophisticated signal processing techniques have been conceived to deal with regime variability. You might also like. Unfortunately, most monitored machines used in the industry operate under nonstationary regimes in order to fulfill the task anallyse which they have been designed.


However, all these techniques rely on the assump-tion of constant— or possibly fluctuating but stationary— operating regime i.

Vibration-based condition monitoring of rotating machines in nonstationary regime. In order to reach this goal, the adopted methodology consists in extending the cyclostationary framework together with its dedicated tools. Help with expert advice. 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. All the lines are busy at the moment, please try again in a moment.

Friday, September 23, – 4: Nowadays, many efficient techniques are well-established, rooted on powerful tools offered in particular by the theory of cyclostationary processes. Dany Abboud 1 AuthorId: This service is produced by Kompass.
