DEF

Montage permettant à un solide S3 de garder un point fixe par rapport à un autre solide S0, tout en lui laissant 3 degrés de liberté.

CONT

Le montage de Cardan est dit idéal lorsqu'il respecte deux conditions : Posséder des armatures extrêmement légères, de masse supposée négligeable et donc nulle. Disposer de paliers de montage, technologiquement sans frottement.

OBS

On semble écrire «cardan» avec ou sans la majuscule initiale (Cardan, du nom de l'inventeur). On semble cependant préférer la majuscule dans les expressions : monté à la Cardan, joint de Cardan, suspension à la Cardan, etc.; et la minuscule quand on utilise le substantif seul.

Key term(s)
