Abstract
(EN)
The present invention provides a deformable membrane assembly 1 comprising an elastic membrane 8 that is held under tension around its edge by a bendable membrane supporting member 2,10, a body of fluid in contact with one face of the membrane, the pressure of the fluid being controllable for adjusting the shape of the membrane, and one or more bending controllers 24 acting on the supporting member 2, 10 to control the bending of the supporting member in response to loading through tension in the membrane. The bending stiffness of the membrane-supporting member 2, 10 varies round its extent to control the profile of the edge of the membrane 8; etc. upon actuation. A variety of different types of bending controllers are disclosed which permit out-of-plane bending of the supporting member 2, 10 but prevent or control in-plane bending or deformation of the supporting member. In some embodiments, the bending controllers permit a degree of controlled in-plane bending of the supporting member 2, 10 in order to control the strain in the membrane 8 upon actuation.

La présente invention concerne un ensemble de membrane déformable (1) comprenant une membrane élastique (8) qui est maintenue sous tension autour de son bord par un élément de support de membrane flexible (2, 10) un corps de fluide en contact avec une face de la membrane, la pression du fluide étant réglable pour ajuster la forme de la membrane, et un ou plusieurs contrôleurs de flexion (24) agissant sur l'élément de support (2, 10) pour commander la flexion de l'élément de support en réponse à une charge par l'intermédiaire d'une tension dans la membrane. La rigidité à la flexion de l'élément de support de membrane (2, 10) varie autour de son étendue pour commander le profil du bord de la membrane (8) etc. lors de l'actionnement. Une variété de types différents de contrôleurs de flexion sont décrits, ce qui permet la flexion hors du plan de l'élément de support (2, 10) mais empêche ou contrôle la flexion dans le plan de commande ou la déformation de l'élément de support. Dans certains modes de réalisation, les contrôleurs de flexion permettent un degré régulé de flexion dans le plan de l'élément de support (2, 10) afin de commander la contrainte dans la membrane (8) lors de l' actionnement.
