Turnover 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.

The second type includes random periodically-correlated waveforms known as second-order cyclostationary. In this work, the nonstationarity of the regime is vibratire to that of the speed— i. However, all these techniques rely on the assump-tion of constant— or possibly fluctuating but stationary— operating regime i. Click on one of the icons to share the company.


Three different but complementary visions have been proposed to deal with the changes induced by the nonstationarity of the operating speed. Vibration-based condition monitoring of rotating machines in nonstationary regime. The first type includes deterministic vibatoire known as first-order cyclostationary.

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

Many tools have been conceived whose performances have been successfully tested on simulated and real vibration signals. Domestic and industrial waste collection and recycling equipment NES. Have you forgotten your login?

Dany Abboud 1 Details. Friday, October 26, – Frequent vibratlire ensuring high quality data. Discover the best events for your business. 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.

But these works remain limited, dispersed and generally not supported by theoretical frameworks. 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. Help with expert advice. Friday, September 23, – 4: Business tools and solutions designed for the global marketplace.

Unfortunately, most monitored machines used in the industry operate under nonstationary regimes in order to fulfill the task for which they have been designed. Frequent updates ensuring high quality data Secure online payment Help with expert advice Dedicated customer service team.
