This service is produced by Kompass. Nowadays, many efficient techniques are well-established, rooted on powerful tools offered in particular by the theory of cyclostationary processes. Many tools have been conceived whose performances have been successfully tested on simulated and real vibration signals. Unfortunately, most monitored toirnante used in the industry operate under nonstationary regimes in order to fulfill machin task for which they have been designed.

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

Inria – Vibration-based condition monitoring of rotating machines in nonstationary regime

Friday, September 23, – 4: Description Key figures Executives Activities. Domestic and industrial waste collection and recycling equipment NES. 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.

Create your web page Haltools: Technical testing and analysis 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.

Vibration-based condition monitoring of rotating machines in nonstationary regime. 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.

Register Forgot your password? In the last decades, vibration-based condition monitoring of rotating machine has gained special interest providing an efficient aid for maintenance in the industry. 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. We have elaborated this strategy by distinguishing two types of signatures.

Dany Abboud 1 AuthorId: INSA de Lyon, But these works remain limited, dispersed and generally not supported by theoretical frameworks. The second type includes random periodically-correlated waveforms known as second-order cyclostationary. The first type includes deterministic waveforms known as first-order cyclostationary.
