Abstract

We propose a combined method for thermal nondestructive testing using optical and ultrasonic stimulation by means of combining individual thermograms obtained at the corresponding time points. The resulting sequences of infrared thermograms provide more efficient identification of defects of various types and can also be processed using well-known algorithms, for example, thermographic signal reconstruction, principal component analysis, etc. We obtained experimental results on a composite CFRP sample imitating aircraft ribs using a robotic manipulator.

光学和超声刺激下复杂形状CFRP制成的产品的主动红外热成像合成数据

摘要

我们通过结合在相应时间点获得的各个温度记录图，提出了使用光学和超声刺激进行热非破坏性测试的组合方法。生成的红外热像图序列可以更有效地识别各种类型的缺陷，并且还可以使用众所周知的算法进行处理，例如热成像信号重建，主成分分析等。我们在复合CFRP样品模拟飞机上获得了实验结果使用机械手操纵肋骨。
