FACILITY TO TEST SAMPLES FOR THERMAL FATIGUE Russian patent published in 2017 - IPC G01N3/60 

FIELD: testing equipment.

SUBSTANCE: facility includes the power frame, mounted on the base, the passive gripper placed on it, the alternating loading device, the test sample electric heating device, the temperature control and monitoring unit, and the thermal loading record facility. The loading device is made in the form of the body with the piezoelement package, installed in it and the working element, made in the form of the disc, the central part of which is the active gripper coaxial to the passive gripper, the peripheral part of the disc is provided with the inertial mass uniformly distributed along the disc circumference, and the middle part is rigidly connected to the body. The facility is equipped with the additional loading device with the axial loading, made in the form of the tubular electric heater with the pipeline, intended for supplying the cooling medium, the mobile traverse, mounted on the frame with the possibility of axial movement and fixation relative to the latter, and the platform, placed on the mobile traverse and equipped with the thermal load record facility. One end of the electric heater is fixed to the base. The mobile traverse is connected to the other end of the electric heater. The body of the alternating loading device is fixed on the platform, and the thermal load record facilities are made in the form of at least three strain-gauge rods.

EFFECT: possibility to adjust the thermomechanical cycle asymmetry, when changing the loading frequency.
