Abstract

L'invention concerne un mécanisme de libération résistant aux vibrations qui comprend un assemblage de manivelle activé par ressort comportant des pivots à Cardan et des actionneurs de forte rigidité à faisceau piézoélectrique placés en opposition. Tous les composants se rapportant à l'assemblage de manivelle activé par ressort sont équilibrés autour du pivot à Cardan afin de résister à des forces de vibration et les actionneurs piézoélectriques sont montés pour répondre à des modes de vibration opposés l'un à l'autre.
