DESCRIPTION:Speakers: Hernandez Fidel ()\nThe goal of this research was to
  implement a new algorithm for the automatic detection of faults in rollin
 g element bearings\, in such a way that it does not depend on the estimati
 on of the shaft rotational speed. The idea was that the algorithm could be
  applied under variable and unknown rotational speed conditions. The propo
 sed algorithm was based on the detection of phase-relationships between sp
 ectral components that emerge when an amplitude modulation appears in the 
 gathered vibration. To do that\, a mode decomposition procedure\, as well 
 as the Hilbert transform\, was applied in order to estimate a detection co
 efficient\, which served as indicator of the presence of the modulation pr
 oduced by the faults. Lock-in amplifiers were used in order to calculate s
 uch an indicator. The effectiveness of the method was validated through ex
 periments preformed by using simulation and real signals. It was proven th
 at the application of the proposed method can lead to an effective detecti
 on of the modulation featuring the existence of rolling element bearing fa
 ults.\n\nhttps://events.isae.fr/event/22/contributions/654/
