Natural roller bearing fault detection by angular measurement of true instantaneous angular speed
TL;DR: In this article, the authors proposed an alternative way of bearing condition monitoring based on the instantaneous angular speed measurement by the help of a large experimental investigation on two different applications, they prove that localized faults like pitting in bearing generate small angular speed fluctuations which are measurable with optical or magnetic encoders.
Natural roller bearing fault detection by angular measurement of true instantaneous angular speed
TL;DR: In this article, the authors proposed an alternative way of bearing condition monitoring based on the instantaneous angular speed measurement using optical or magnetic encoders, and demonstrated the benefits of measuring angular speed with the pulse timing method through an implicit angular sampling which ensures insensitivity to speed fluctuation.
Journal ArticleDOI
Microstructure analysis of 7050 aluminum alloy processed by multistage aging treatments`
TL;DR: In this article , the authors investigated the bimodal microstructure feature by taking into account both density and morphology of precipitates, which are transformed from the retrogression and reaging (RRA) along with interrupted aging (T6I4) conditions within the 7050 aluminum alloy.

Modal Behavior Monitoring of a Discrete Evolutive Structure
Laurence Renaudin,Didier Rémond +1 more
TL;DR: In this article, an integrated modal identification method in time domain allowing the monitoring of mode shapes is presented. But the method is limited to three pendulums, one of them offering the possibility to move its mass, and changes in position of this mass introduce small changes on natural frequencies but significant changes in modal shapes under controlled operating conditions.
