Kind Code:
A1
Abstract:
[Problem] The present invention provides a fatigue testing device in which a roughly cylindrical metal material specimen is fixed to a mounting unit on the fixed end side of the specimen and axially rotated, and the rotary bending fatigue strength of the specimen is measured by applying a load vertically downward on the free end side of the specimen . [Solution] This fatigue testing device is characterized in that: the mounting unit is equipped with a temperature measuring means that axially rotates in conjunction with the specimen and the mounting unit; the temperature measuring means is provided with a thermocouple, the leading end of which is positioned in the interior of the specimen; and information pertaining to the temperature of the specimen interior detected by the thermocouple is transmitted to the exterior by a transmitting means.
