Abstract

Machine de traction-compression à chaud L’invention concerne une machine de traction-compression à chaud d’une éprouvette longitudinale (30) comprenant : un dispositif de déformation (15) pour étirer et comprimer ladite éprouvette longitudinale (30) ; un organe de chauffage (38) pour fournir de l’énergie thermique à ladite éprouvette (30) ; un extensomètre (44) adapté à être porté en contact avec ladite éprouvette (30) pour mesurer l’amplitude d’allongement ; un organe de commande (60) commandant ledit dispositif de déformation (15) durant une période de temps donnée à basse fréquence et selon une amplitude fonction de l’amplitude mesurée par ledit extensomètre (44). La machine comprend en outre un actionneur (54) relié audit extensomètre (44), et ledit organe de commande (60), commande après que ladite période de temps a expiré, ledit actionneur (54) pour écarter ledit extensomètre (44) de ladite éprouvette (30), et ledit dispositif de déformation (15) durant une autre période de temps donnée à haute fréquence. (Figure 1)Hot tension-compression machine The invention relates to a hot tension-compression machine for a longitudinal specimen (30) comprising: a deformation device (15) for stretching and compressing said longitudinal specimen (30); a heater (38) for supplying thermal energy to said specimen (30); an extensometer (44) adapted to be brought into contact with said specimen (30) to measure the amplitude of elongation; a control member (60) controlling said deformation device (15) during a given period of time at low frequency and according to an amplitude dependent on the amplitude measured by said extensometer (44). The machine further comprises an actuator (54) connected to said extensometer (44), and said controller (60), controls after said period of time has expired, said actuator (54) to move said extensometer (44) away from said specimen (30), and said deformation device (15) for another given high frequency period of time.
