Experimental apparatus for measuring heat deformation and thermal fatigue

摘要

The present invention uses an infrared heating device as a heating source and can control the experimental atmosphere in the experimental device.Thermal deformation and high temperature material designed to directly measure the thermal deformation and thermal fatigue phenomena of the specimen under test in the experimental device. An apparatus for simulating thermal fatigue, comprising: an infrared heater for heating a specimen to be subjected to high temperature thermal deformation and thermal fatigue testing; An experiment in which a transmission window through which infrared rays radiated from the infrared heater are transmitted, a temperature control device for controlling a temperature in an experiment apparatus, and an inlet, an outlet of an atmosphere gas for controlling an atmosphere in an experiment apparatus, and a charging inlet for loading a specimen A chamber; A specimen supporter disposed in the test chamber to support the specimen; A non-contact distance sensor for measuring the amount of deformation due to thermal deformation and defects due to thermal fatigue during or after the test of the specimen in the test chamber; It provides a test device for thermal deformation and thermal fatigue measurement consisting of; a specimen support moving means for reciprocating between the specimen support mounted on the specimen between the lower portion of the non-contact distance sensor and the lower portion of the infrared heating device.
