A vertical translation mechanism for reconfiguring the hull form of a reconfigurable vessel having independently movably side hulls and a center hull is disclosed. The vertical translation mechanism includes a hydraulic-force actuator and a nonmetallic bearing. The hydraulic force actuator comprises a rod that is disposed within a hydraulic cylinder. Responsive to changes in hydraulic pressure in the cylinder, the rod is extended or retracted therefrom. Movement of the rod controls the vertical translation of the center hull and its rotational attitude relative to the side hulls.
L'invention concerne un mécanisme de translation verticale (110) destiné à reconfigurer la forme de la coque d'un navire reconfigurable comprenant des coques latérales (102) à mouvement indépendant et une coque centrale (108). Le mécanisme de translation verticale (110) comprend un actionneur à force hydraulique et un palier non métallique (214). L'actionneur à force hydraulique comprend une tige (220) disposée dans un cylindre hydraulique (218). En réponse à des changements de pression hydraulique dans le cylindre (218), la tige (220) s'étend ou se rétracte par rapport à celui-ci. Le mouvement de la tige (220) commande la translation verticale de la coque centrale (108) et son attitude de rotation par rapport aux coques latérales (102).
