摘要
介绍了用机械阻抗法检测金属蜂窝结构脱粘缺陷的方法。描述了机械阻抗检测的原理、探头和仪器的结构,对检测参考试块人工缺陷的试验和结果,以及初步应用于产品检验的概况。结论认为,机械阻抗法检测金属蜂窝结构脱粘缺陷的灵敏度和可靠性都能满足有关技术文件的要求。指出了机械阻抗法的优缺点,以及单触点探头与双触点探头在应用方面的差异。
This paper describes a study on inspection of bonding defects in metal honeycomb structures by mechanical impedance method. It covers principle, structures of probes and instrument, experiments in which artificial defects are detected and results, and application to production process. Conclusion is that the sensitivity and reliability of the method satisfies the related specifications. This paper points out the advantages and disadvantages of mechanical impedance method and the difference in application between probe having two contactors and probe having one contactor.
