声发射检测通过采集材料本身产生的AE信号,实现对结构损伤处AE源的定位及损伤状态评估。正确认识声发射信号波在结构中的传播规律,有助于实现起重机械声发射检测传感器优化布置及对损伤状态的量化判断,特别对于声发射技术应用在起重机械健康监测方面具有积极的意义。
Acoustic emission detection by collecting the AE signal generated by the material itself to achieve structural damage AE source localization and damage status assessment. Correctly understanding the propagation law of acoustic emission signal wave in the structure can help realize the optimal arrangement of the acoustic emission detection sensor for crane and quantify the damage state, especially for the application of acoustic emission technology in the health monitoring of crane. significance.
