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.

Nowadays, many efficient techniques are well-established, rooted on powerful tools offered in particular by the theory of cyclostationary processes. This service is produced by Kompass.

Many tools have been conceived whose performances have been successfully tested on simulated and real vibration signals. However, all these techniques rely on the assump-tion of constant— or possibly fluctuating but stationary— operating regime i.

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 dr tools.

We have elaborated this strategy by distinguishing two types of signatures. In order to reach this goal, the adopted methodology consists in extending the cyclostationary framework together with its dedicated tools. In this work, the nonstationarity of the regime is confined to that of the vivratoire i.

Three different but complementary visions have been proposed to deal with the changes induced by the nonstationarity of the operating speed. The data we collect are only those necessary for the proper use of our service. Friday, October 26, – 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.

Help with expert advice. Unfortunately, most monitored machines used in the industry operate under nonstationary regimes in order to fulfill the task for which they have been designed.
