摘　　要：为实现对金属-含能材料粘接结构界面粘接质量的无损评价,提高其结构安全性,本研究以金属环-含能材料界面脱粘缺陷的无损检测为研究对象,提出了基于电磁超声共振的金属环-含能材料结构界面脱粘缺陷非接触检测方法,制作了专用小型电磁超声探头,搭建了电磁超声环形自动扫查系统,对金属环-含能材料脱粘缺陷模拟试件进行了自动扫查成像,开发了相应的信号处理方法,验证了该技术对于金属环-含能材料界面脱粘缺陷非接触检测的可行性和检测能力。In order to realize the non-destructive evaluation of the interface bonding quality of metal-energetic material bonding structure and improve its structural safety,the non-destructive testing of debonding defect in metal ring and energetic material bonding structure is studied in this paper.A new non-contact testing method based on electromagnetic acoustic resonance is proposed for the inspection of the metal ring-energetic material structure.A special miniature electromagnetic acoustic transducer is made,and an automatic scanning system of electromagnetic acoustic testing is developed.The simulated debonding defects specimen were scanned and imaged automatically.A corresponding signal processing method was developed.The feasibility and detection ability of this technology for non-contact detection of debonding defects of metal ring-energetic materials interface were verified.
