Diagnosing the vibrating behaviour of the PWR internal structures using expert systems techniques and algorithmic treatment

Creators

Description

In order to automate the diagnostic of the vibrating behaviour of PWR internal structures, a program based on the expert system technology is added to the present time numerical software, the calculation comprises three stages: the signal is first processed with a Fourier transformation, then with a quadrature and an average thus giving the Noise Power Spectral Density. From this function a few characteristic resonances (between 5 and 10) are extracted and transmitted to the expert software

Abstract (French)

De maniere a automatiser le diagnostic du comportement vibratoire des internes d'un REP on associe au logiciel numerique actuellement employe, un logiciel s'appuyant sur la technique des systemes experts; le traitement propose comporte trois etapes: le signal subit d'abord une transformation de Fourier suivie d'une quadrature et d'un moyennage pour obtenir la DSP (Densite spectrale de puissance), puis un traitement classique extrait de la DSP un fond continu et un tres petit nombre de resonances (entre 5 et 10). Ensuite un micro-systeme expert analyse l'evolution temporelle des spectres
