Title
(EN) SYSTEM FOR VERIFICATION OF TESTING MACHINE SPEED
(FR) SYSTÈME DE VÉRIFICATION DE LA VITESSE D'UNE MACHINE DE TEST
Abstract
(EN)
The present disclosure relates to a system for verification of the speed of crosshead travel in a materials testing device. A linear displacement device is mounted on the crosshead of the materials testing device. The linear displacement device measures the position and displacement of the crosshead during the test. A timer interval counter measures the time of travel of the crosshead during the test. This measurements allow for accurate calculation of the average speed of the crosshead travel, based on the difference between the position values divided by the elapsed time.

La présente invention concerne un système de vérification de la vitesse de déplacement de crosse dans un dispositif de test de matériaux. Un dispositif de déplacement linéaire est monté sur la crosse du dispositif de test de matériaux. Le dispositif de déplacement linéaire mesure la position et le déplacement de la crosse pendant le test. Un compteur d'intervalle de temporisateur mesure le temps de déplacement de la crosse pendant le test. Ces mesures permettent un calcul précis de la vitesse moyenne du déplacement de la crosse, sur la base de la différence entre les valeurs de position divisées par le temps écoulé.
