Actionneur direct à Précharge Parallèle

L’actionneur direct à Précharge Parallèle (PPA) est un empilement de composants piézoélectriques multicouches (MLA). La précharge est obtenue par un ressort extérieur en acier inoxydable qui protège le MLA contre les forces de traction et fournit à l’utilisateur des interfaces mécaniques pour une intégration aisée. Le cadre de précharge applique une précharge optimum sur le MLA, ce qui permet une plus grande durée de vie et de meilleures performances en dynamique que les actionneurs préchargés traditionnels.

Conçu par CEDRAT TECHNOLOGIES, ce nouveau modèle d’actionneur direct résulte de développements effectués pour le compte du CNES, l’Agence Française de l’Espace. Les PPA sont plus légers et compacts que les actionneurs directs avec les mêmes propriétés électromécaniques. La forme compacte permet aussi une meilleure intégration dans l’assemblage.
