摘要
介绍薄板中声发射信号的一些特点和如何利用声发射时域波形识别不同故障源的基础理论知识,以及利用波形识别技术在雷达罩和碳纤维复合材料等试件上所获得的一些试验结果。
The significant role played by acoustic emission waveform and frequency analysis for fault identifi-cation of CFRP composite and aircraft radome are outlined. Some experimental results using simulated acoustic e-mission sources are also presented.
