Problems solved by technology

[0003] Since the vibration signal of the test piece structure needs to be collected in a thermal environment as high as 1000°C, the maximum measurement temperature of the high-temperature acceleration sensor cannot meet the requirements and cannot be used. The non-contact measurement method is easily affected by the quartz lamp tube during high-temperature heating. It leads to inaccurate measurement results. At the same time, if the gap between the quartz lamp tubes is too large, the consistency of the surface temperature of the test pie
