Description
Summary:In this study, we developed a real-time executing source location system for anisotropic thin structures such as CFRP (Carbon Fiber Reinforced Plastics) tanks. The system consists of AE sensors, an A/D converter on a PC and a computer with proprietary software. We suggest two algorithms to realize the real-time executing source location. The first algorithm is a frequency filtering algorithm utilizing a fast continuous wavelet transform. The second algorithm is a fast source location calculation algorithm for unidirectional anisotropic structures. In the second algorithm, the affine coordinate transform is used. The calculation time for each source location is reduced to less than 15 ms with reasonable accuracy.
