Abstract

L’invention concerne un dispositif (1) de caractérisation d’un ressort, par exemple un ressort hélicoïdal, s’étendant selon un axe (X), comportant un premier organe de fixation (3) destiné à être fixé à une première zone dudit ressort, un second organe de fixation (4) destiné à être fixé à une seconde zone dudit ressort, des moyens (10, 20) de mise sous contrainte dudit ressort aptes à déplacer en translation selon ledit axe (X, Y) le premier organe de fixation (3) par rapport au second organe de fixation (4), entre une position de repos et au moins une position de mise sous contrainte du ressort, des moyens (21, 22) de mesure de l’effort appliqué par le ressort selon ledit axe (, YX) entre les premier et second organes de fixation (3, 4) , en position de mise sous contrainte, et des moyens (11, 13, 24) de mesure du déplacement, selon ledit axe (X, Y), du second organe de fixation (4) par rapport au premier organe de fixation (3). Figure à publier avec l’abrégé : Figure 1The invention relates to a device (1) for characterizing a spring, for example a helical spring, extending along an axis (X), comprising a first fixing member (3) intended to be fixed to a first zone of said spring, a second fixing member (4) intended to be fixed to a second zone of said spring, means (10, 20) for stressing said spring capable of moving in translation along said axis (X, Y) the first member (3) with respect to the second fixing member (4), between a rest position and at least one position in which the spring is stressed, means (21, 22) for measuring the force applied by the spring along said axis (, YX) between the first and second fixing members (3, 4), in the stressing position, and means (11, 13, 24) for measuring the displacement, along said axis (X, Y ), of the second fixing member (4) with respect to the first fixing member (3).
