Abstract(s) :

(Anglais) This paper proposes to highlight two aspects of denoising in vibration analysis. The first aspect aims to reveal the singularities while the second eliminates the noise in order to keep the useful signal. These two aspects are the cause of the surjection of denoising and especially due to the choice of the performance criteria. This paper highlights the use of denoising through these aspects, and then proposes a performance criterion suitable for vibration analysis as part of a noise suppression, to apply a processing method. This paper provides a reflection on the use of discrete wavelet transform through the various parameters which are used during processing.
