Abstract

Isolateur de vibrations. Il comprend entre deux éléments rigides destinés à être reliés aux deux parties d'un dispositif à isoler, une masse d'un matériau amortisseur élastomère. L'un au moins desdits éléments rigides est constitué par une résine époxy contre laquelle l'élastomère est adhérisé. Application, notamment comme adaptateur de fréquence monte entre un rotor et une pale d'hélicoptère.
