摘要
The present invention is a cryogenic thin plate tension and fatigue test jig structure for improving the accuracy of the test by generating a tensile force in the axial direction without generating the slip phenomenon of the thin plate during the fatigue test of the metal sheet under cryogenic environment and using the same The sheet tension and fatigue test method, the sheet tension and fatigue test jig structure according to the present invention is disposed parallel to each other and a pair of bite jig is fixed between the one end of the thin plate to be tested therebetween; A test fixture jig connected to the actuator and moving in one direction and having a space portion into which the bite jig is inserted; It is characterized in that it comprises a plurality of leveling bolts are helically coupled to the test jig, the inner end portion is moved by an arbitrary distance from the inside of the space portion to adjust while fixing the posture of the bite jig inside the space portion.
