Abstract

L’invention propose un procédé de mesure non destructive de fréquences de résonance d'un faisceau électrique (12) comportant au moins un câble (14) suspendu entre au moins deux moyens de fixation (18) à un support rigide (16), ledit faisceau (12) étant susceptible d'être soumis à des vibrations transmises par ledit support (16) et comportant au moins un fil électrique (24a, 24b), caractérisé en ce qu'il comporte au moins une étape (ET2) au cours de laquelle on relie un accéléromètre (34) à une première extrémité (42) d'un fil (24a, 24b) du faisceau, et une seconde extrémité (44) de ce fil (24a, 24b) à un système d'acquisition d'intensités électriques (38), et une étape (ET3) au cours de laquelle on soumet le support rigide (16) à des vibrations mécaniques d'amplitude constante sur une plage de fréquences déterminées pour établir des courbes (C1, C2) de réponse en fréquence d'intensités électriques dont les pics correspondent aux pics de réponse en fréquence mécanique dudit faisceau (12).
