La mesure en tribologie

TribologieTribologie

La tribologie, ou science des frottements, consiste à produire un déplacement relatif entre deux corps sous une charge contrôlée. L'échantillon en contact avec une bille montée sur un bras élastique subit un déplacement rotatif ou alternatif. La faible déflection du bras permet de déterminer les forces tangentielles et donc le coefficient de frottement induit par ce déplacement. Les taux d'usure pour l'échantillon et pour le matériau antagoniste sont calculés en déterminant la perte de volume par unité de distance parcourue.

Mesure Tribologie

Cette méthode simple facilite la détermination et l'étude des frottements et d'usure sur un grand nombre de combinaisons de matériaux, avec la gestion contrôlée de paramètres multiples tels que la durée de test, la pression de contact, la vitesse, la température, l'hygrométrie, la lubrification, etc.
