Abstract

L'allongement proportionnel à la tension de la tige du boulon est déterminée par mesures d'ultrasons : le changement de longueur est obtenu dans un calculateur, à partir de la différence de déphasage de l'écho avant et après le serrage du boulon. Cet allongement est comparé à un allongement standard déterminé sur un boulon type au cours d'essais. Le dispositif comporte une tête de palpeur 4, avec un palpeur 5 appliqué contre la tête 7 du boulon, dans une douille 2, montée entre le boulon et un cliquet 1.
