TEMPERATURE TEST DEVICE OF SPLIT HOPKINSON TENSILE BAR

摘要

The present invention relates to a temperature test device using a split Hopkinson tension bar, which includes input and output bars (11 and 15) to which opposite ends of a specimen (1) are screw-coupled, a shock tube (19) automatically applying stress waves to the input bar (11) when the specimen (1) is heated and the input and output bars (11 and 15) are cooled at the same time so that the specimen (1) reaches a target temperature and the input and output bars (11 and 15) satisfy a set temperature, a heating means (31) instantly heating a gauge part (3) of the specimen (1), and a cooling means (33) cooling the input and output bars (11 and 15). The present invention is advantageously available to an acquisition of temperature-dependent dynamic tensile property through a temperature test using a split Hopkinson tension bar.
