AI Technical Summary
Existing technologies suffer from errors in high-temperature experiments, such as thermal deformation of metal fixtures, diffuse reflection of laser displacement gauges, and thermal creep of extensometers. These errors lead to large errors in strain measurement of waste glass concrete, especially severe distortion in the phase transition temperature range.
By employing a dual-mode sensing and dynamic compensation method, combining a high-temperature polarized laser displacement meter, a silicon carbide ceramic extensometer, and a pressure sensor array, the temperature field is precisely controlled through multiple sets of heating element arrays. The temperature distribution is observed using a high-temperature thermal imager, and dynamic compensation is performed through an elastic diaphragm and a pressure sensor array to reduce displacement measurement errors.
It achieved displacement measurement error control within ±0.05mm in the range of 20~1200℃, significantly improving measurement accuracy by 6 times.
