Apparatus and method for fatigue testing machine at low temperatures combined with cycle refrigerant spray

摘要

The present invention is attached to cold circulating refrigerant injector device rotating bending fatigue tests with high test speed so as to be in a short time by high-cycle fatigue tests at cryogenic temperatures through a blood test apparatus , for holding both ends of the specimen and to be a full , each time a pair of fixed , one side of the total amount of time a link with weight bending test section to rotate bending and rotation occurs in the specimen by the specimen tilted direction; Relates to a low-temperature fatigue test device is attached , characterized in that the injector refrigerant circulating coolant is continuously circulated as a refrigerant which comprises a so poured onto the specimen until the isothermal state before rotation of the bending specimen . ;
