Abstract
Le dispositif d'entraînement ultrasonique proposé est destiné à être utilisé comme entraîneur de pièces mobiles dans les champs de rayonnement direct et secondaire (p. ex., dispersion). Habituellement, ces dispositifs d'entraînement comptent des moteurs électromagnétiques, toutefois le champ irradiant détruit leur isolement électrique et certaines pièces de moteur deviennent radioactives dans les champs de rayonnement fort. Certains moteurs actuels comportent un actionneur ultrasonique servant d'élément d'entraînement. De tels moteurs comportent un élément résonnant piézoélectrique auquel l'élément de friction est attaché à l'aide d'une couche adhésive organique. La couche peut également se décomposer sous l'influence du rayonnement. Dans le dispositif d'entraînement proposé, les éléments résonnants piézoélectriques, les éléments de friction et la couche de friction sont disposés de telle façon que la jonction de ces éléments avec l'élément résonnant piézoélectrique est protégée du champ irradiant par le corps de l'élément résonnant piézoélectrique ou par le corps de l'élément d'entraînement.
