Abstract

a. Machine d'essais de fatigue permettant d'exercer des efforts de traction suivant au moins deux axes de charge coplanaires d'une éprouvette ; b. Suivant chaque axe de charge deux ensembles de liaison relient une tête mobile il et une tête fixe 12 de l'éprouvette 10 à un vérin 40 et à un dispositif de mesure 50. Chaque ensemble de liaison comprend un parallélogramme déformable coplanaire à l'éprouvette dont les grands côtés sont constitués par des éléments flexibles 60 perpendiculairement à l'axe de charge et dont les petits côtés sont reliés au vérin, ou au dispositif de mesure, et à un mors de traction 70 comprenant une cavité de révolution 72 et une lumière perpendiculaire 73 à l'axe de charge permettant le libre passage de la tête de l'éprouvette et liaison prismatique de cales planes à faces de révolution 76 avec la tête de l'eprouvette, les cales pouvant tourner à frottement dans la cavite; c. Essais de fatigue engendrant des efforts de traction pluriaxiaux et d'amplitudes différentes.
