Abstract

Appareil de mesure des propriétés de matériaux à précision améliorée par l’utilisation de capteurs laser L’invention concerne un appareil de caractérisation de la raideur dynamique complexe d’une éprouvette (1) comprenant : - une enceinte thermique pour chauffer ou refroidir l’éprouvette (1) ;- un excitateur adapté pour appliquer une déformation à l’éprouvette ;- et un dispositif (19) pour déterminer la raideur dynamique complexe du matériau. Selon l’invention, l’appareil comporte un système de mesure différentielle de la déformation de l’éprouvette comportant au moins un jeu de deux capteurs laser (18a) comprenant des parties optiques d’émission et de réception (18b) de faisceaux laser, montées mécaniquement solidaires par un support commun (22) situé à l’extérieur de l’enceinte thermique, ce système de mesure différentielle (18) mesurant les amplitudes vibratoires à l’aide des faisceaux laser (F1, F2, …), d’une part, de points d’une structure d’application d’une déformation à l’éprouvette situé à l’intérieur de l’enceinte thermique et d’autre part, de points d’une structure de réception de la force liée à la déformation de l’éprouvette situé à l’intérieur de l’enceinte thermique. Figure pour l’abrégé : Fig. 3A.
