摘要(Abstract)：

在分布式碳纤维复合材料-光纤光栅(CFRP-OFBGs)复合板的早期损伤监测中,传统方法如最大检测算法MDA(Maximum detection algorithm,MDA)检测效果较好,但计算空间与时间复杂度都很高,不适用于工程计算.因此,提出了一种新的快速三角波监督定位策略.该策略基于相同的反射光谱波长偏移,通过检测三角边界来获得近似结果.通过CFRP-OFBGs复合板压力实验,比较了本算法与最大检测算法在检测精度和准确度上的不同.结果表明:在相同实验环境和参数下,虽然精度下降约15%,但不影响识别准确度.此外,相较MDA算法,三角波监督检测策略能在CPU执行时间上大约快1倍,因而是一种相对经济有效的检测模型,能满足大型工程损伤检测需求.
