METHOD FOR TESTING AN OBJECT FOR THE COMBINED IMPACT OF EXTERNAL FACTORS Russian patent published in 2022 - IPC G01N3/18 

FIELD: objects testing.

SUBSTANCE: invention relates to the field of testing objects for the combined effects of external factors. The test method consists in the simultaneous impact on the test object (TO), placed in a climatic chamber, mechanical and thermal loads. Prior to installation in the climatic chamber, the TO is installed through heat-insulating plates between the base and the adapter plate of the technological device, containing the base connected by guides to the adapter and top plates, packs of sequentially assembled Belleville springs placed between the plates on the guides, clamping nuts mounted on the guides above the top plate. The TO in the technological fixture is loaded on a press machine along the TO axis to a predetermined compressive force, the stress-strain state of the TO is fixed by screwing nuts on the guides of the TO, then the TO in the production jigs is placed in a climatic chamber and the temperature is applied to the TO.

EFFECT: approximation of test modes to real operating conditions with the provision of temperature effects on the TO at a temperature difference and a given compressive force.
