Abstract

L'invention concerne un système d'amortissement passif de vibrations mécaniques générées par une structure vibrante supportée par un support, le système comprenant un transducteur interposé entre la structure vibrante et le support pour transformer l'énergie mécanique des vibrations en énergie électrique, se caractérisant par le fait que : - le transducteur comporte : ○ une structure flextensionnelle présentant un premier axe (et un second axe perpendiculaires entre eux, ○ un empilement d'éléments piézoélectriques adapté pour produire de l'énergie électrique lorsqu'il est contraint, lequel empilement est contraint en compression par la structure flextensionnelle selon le premier axe de sorte qu'une déformation de ladite structure modifie la contrainte en compression appliquée sur ledit empilement, - deux fixations périphériques sont solidaires de la structure flextensionnelle, chacun des fixations étant disposée selon le second axe, ▪ une première fixation pour la solidarisation de la structure flextensionnelle à la structure vibrante, ▪ une seconde fixation pour la solidarisation de la structure flextensionnelle au support, ▪ au moins une des fixations intègre une suspension élastique, - un shunt est relié à l'empilement piézoélectrique de manière à dissiper tout ou partie de l'énergie électrique produite par la contrainte appliquée sur ledit empilement piézoélectrique.
