Abstract
Méthode et appareil pour mesurer l'effort de cisaillement exercé sur une première surface (4a, 27) du fait de son engrènement avec une deuxième surface (3) représentée par un élément sous forme de feuille (1). La deuxième surface est constituée de parties en relief (4) dont les extrémités supérieures sont déviées, dans une direction parallèle au plan de la feuille, lorsque la force s'exerce sur elles. Un appareil (7) enregistre le déplacement de ces extrémités, et un autre appareil calcule l'amplitude et la direction de la force de cisaillement par référence à ce déplacement. La description concerne plus particulièrement l'utilisation de cette invention pour mesurer la force de cisaillement exercée sur un pied humain et celle des pinces mécaniques utilisées pour saisir des composants au cours d'un processus d'assemblage robotisé.
