Description

technical field [0001] The invention relates to a test device, in particular to an oxyacetylene-based response online test device for special environmental materials. Background technique [0002] The characterization and evaluation of special environmental materials such as ultra-high temperature anti- / insulation materials and infrared wave-transmitting materials require a series of ground simulation and online testing methods and devices for material response. The main ground simulation equipment includes wind tunnels, arc heaters, oxyacetylene, etc.; The material response online test device mainly includes: infrared thermal imager, colorimetric pyrometer, thermocouple to measure material surface temperature, internal layer temperature; strain gauge, laser extensometer to measure material strain. [0003] Ground simulation equipment such as hypersonic wind tunnels, shock wave wind tunnels, and arc heaters are limited in scope of use, complex equipment installation and comm...

AI Technical Summary

Problems solved by technology

However, because the ground simulator represented by oxyacetylene is limited by many harsh test environments such as high temperature and pressure, the traditional contact online test device cannot meet the test requirements. For the online test of surface temperature and strain of special environmental materials, it is necessary to use Non-contact online measuring device
