In this case, these techniques fail in analyzing the produced vibration tojrnante. Other classifications for some countries NAF Rev. The first type includes deterministic waveforms known as first-order cyclostationary. Unfortunately, most monitored machines used in the industry operate under nonstationary regimes in order to fulfill the task for which they have been designed.

This service is produced by Kompass. Help with expert advice.

Dany Abboud 1 Details. Create your vibeatoire page Haltools: In order to reach this goal, the adopted methodology consists in extending the cyclostationary framework together with its dedicated tools.

Information available as an option. 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 data we collect are only those necessary for the proper use of our service.


We have elaborated this strategy by distinguishing two types of signatures. Click on one of the icons to share the company. But these works remain limited, dispersed and generally not supported by theoretical frameworks. Please fill in your login and password Login.

In this work, the nonstationarity of the regime is confined to that of the speed— i. Friday, October 26, – Frequent updates ensuring high quality data. Vibration-based condition monitoring of rotating machines in nonstationary regime. 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.

Business tools and solutions designed for the global marketplace. INSA de Lyon, 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.


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