Title (EN) CONTROLLING HEAT TRANSFER IN ACTIVE MATERIAL ACTUATORS USING EXTERNAL ELEMENTS
(FR) RÉGULATION DE TRANSFERT DE CHALEUR DANS DES ACTIONNEURS DE MATIÈRE ACTIVE À L’AIDE D’ÉLÉMENTS EXTERNES
Abstract: front page image
(EN)An actuator includes a thermally activated active material member, and an external element configured to selectively engage the member and presenting a predetermined rate of thermal conductivity configured to transfer heat energy to and/or from the member, so as to reduce the actuation period or rate of cooling after actuation, when engaged.
(FR)Selon l’invention, un actionneur comprend un élément de matière active thermiquement activé, et un élément externe configuré pour mettre sélectivement en prise l’élément et présentant un taux prédéfini de conductivité thermique configuré pour transférer de l’énergie thermique au et/ou depuis l’élément, de manière à réduire la période ou vitesse d’actionnement de refroidissement après l’actionnement, une fois en prise.
