Turnover Information available as an option. The second type includes random periodically-correlated waveforms known as second-order cyclostationary.
This service is produced by Kompass. But these works remain limited, dispersed and generally not supported by theoretical frameworks. Three different but complementary visions have been proposed to deal with the changes induced by the nonstationarity of the operating speed. Share this company profile.
In this case, these techniques fail in analyzing the produced vibration signals. Unfortunately, most monitored machines used in tournane industry operate under nonstationary regimes in order to fulfill the task for which they have been designed.
Friday, October 26, – Many tools have been conceived whose performances have been successfully tested on simulated and real vibration signals.
Inria – Vibration-based condition monitoring of rotating machines in nonstationary regime
The first type includes deterministic waveforms known as first-order cyclostationary. The proposed solution consists in generalizing the first-order cyclostationary class to the more general first-order cyclo-non-stationary machinf which enfolds speed-varying deterministic signals.
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.
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. Dany Abboud 1 Details. Register Forgot your password? Help with expert advice. In this work, the nonstationarity of the regime is confined to that of the speed— i.
In order to reach this goal, the adopted methodology consists in extending the cyclostationary framework together with its dedicated tools. Nowadays, many efficient techniques are well-established, rooted on powerful tools offered in particular by the theory of cyclostationary processes. Have you forgotten your login?
