Abstract

L'invention concerne un système de test (100) qui comprend un transducteur de force (102), un support (108), un capteur (124) et un dispositif de commande (120). Le transducteur de force (102) est configuré pour générer une sortie de force (114) qui est indicative d'une force appliquée au transducteur (102) et comprend un côté actif (116) et un côté fixe (118). Le support (108) est connecté au transducteur de force (102) et est configuré pour porter un échantillon de test. Le capteur (124) est configuré pour générer une sortie de capteur (122) qui est indicative d'une vitesse du côté actif (116) par rapport au côté fixe (118). Le dispositif de commande (120) est configuré pour recevoir la sortie de force (114) et la sortie de capteur (122), calculer une compensation d'amortissement sur la base de la sortie de capteur (122), une estimation de constante d'amortissement associée à un mouvement du transducteur (102) et du support (108), et à une masse secondaire comprenant une masse du transducteur (102) et du support (108), et générer une mesure de force corrigée sur la base de la sortie de force (114) et de la compensation d'amortissement.
