Create your web page Haltools: Unfortunately, most monitored machines used in the industry operate under nonstationary regimes in order to fulfill the task for which they have been designed.

In this case, these techniques fail in analyzing the produced vibration signals.

Discover the best events for your business. The data we collect are only those necessary for the proper use of our service. In the last decades, vibration-based condition monitoring of rotating machine has macine special interest providing an efficient aid for maintenance in the industry.

Domestic and industrial waste collection and recycling equipment NES. The second type includes random periodically-correlated waveforms known as second-order cyclostationary.


In order to reach this goal, the adopted methodology consists in extending the cyclostationary framework together with its dedicated tools. Have you forgotten your login? Frequent updates ensuring high quality data.

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. Friday, October 26, – Share this company profile.


Technical testing and analysis But these works remain limited, dispersed and generally not supported by theoretical frameworks. Analysse de Lyon, Other classifications for some countries NAF Rev.

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

Dany Abboud 1 AuthorId: Vibration-based condition monitoring of rotating machines in nonstationary regime. You might also like. You vibrayoire also like: Three different but complementary visions have been proposed to deal with the changes induced by the nonstationarity of the operating speed.


Dany Abboud 1 Details.


This service is produced by Kompass. Many tools have been conceived whose performances have been successfully tested on simulated and real vibration signals. Friday, September 23, – 4: 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 machkne signals.

All the lines are busy at the tornante, please try again in a moment. 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.
