摘　　要：针对结构热试验模拟的精细化需求,对石英灯阵加热器设计进行研究。从适当超载、布局台理、标准化以及安全性四个方面总结石英灯加热器设计的量化设计原则。研究石英灯的电阻、功率、时间常数与功率调节器输出电压的函数关系,指出采取温度分段的必要性。工程应用实践表明:采用标准化设计能够减少加热器设计、生产的工作量及工作难度,减少加热器组装和后期检查的工作量和难度,有效缩短试验周期,提高试验可靠性。Traditional contract metrology was hard to meet requirements as the standard of thermal deformation measurement was being higher thermal strength test.Several non-contract optical metrologies were compared in this paper.Then the digital image correlation metrology was chose for the research experiment of non-contract metrology for deformation measurement at 1200℃.The experiment showed the measured value was close to the real strain.The further research would be done in the following steps to improve the accuracy of digital image correlation metrology and estimate the application prospect of this metrology in thermal strength test.
