摘要：
针对固体发动机药柱结构内部应变响应测量难题，提出了一种基于光纤光栅传感器的内埋式应变测量方法。设计了内埋光纤光栅应变传感器的试验器并对其开展了冷增压试验，获得了试验器药柱内部环向应变与轴向应变值。试验结果表明，提出的测试方法可以获取药柱内部的环向和轴向应变。研究成果可为光纤光栅传感器在固体发动机药柱结构测量中的进一步应用奠定基础，为固体发动机监测技术的发展与应用提供参考

Abstract：
An embedded strain measurement method based on fiber bragg grating sensor was proposed to solve difficult problems in measuring the internal strain response of solid rocket motor grain. The solid rocket motor tester of embedded fiber bragg grating strain sensor was designed, and the cold pressurization test was carried out on the tester. The axial and circumferential strains in the grain structure were obtained under cold pressurization test. Research shows that the proposed test method can obtain the circumferential strain and axial strain in internal grain. The research results can lay a foundation for the further application of fiber bragg grating sensor in the measurement of solid motor grain structure, and can provide a reference for the development and application of solid motor monitoring and detection technology.
