Experimental Research on Health Monitoring of Cracked Structure Repaired by Composite Patch Using Lamb Waves

  • 摘要: 利用损伤对结构中Lamb波传播特性的影响,对用复合材料补片修补后的金属损伤结构的健康监测方法进行了试验研究。在用复合材料补片对含裂纹的铝合金试件进行修理后,在复合材料补片周围安装了3个压电陶瓷传感器。压电陶瓷传感器在试验中的响应数据被周期性的记录下来。为了描述修补后损伤金属结构的健康状态,定义了3种基于传感器响应数据的损伤指数。试验结果表明,基于波形相关性的损伤指数可更好的描述修补结构的损伤发展过程。研究结论在某型飞机疲劳试验中得到了应用。
