针对所研究的具有新功能的PIND检验系统,提出了振动信号周期性识别方法和冲击响应信号判断技术,改进了PIND检验技术,基本上解决了PIND生产检验中常见的误判问题。试验证明,所提出的冲击响应信号判断技术,还可以识别一些特定情况下的漏检。这对于提高航天产品的可靠性具有重要意义,对PIND标准修订也具有直接的指导意义。 Aiming at the PIND inspection system with new functions, a periodic identification method of vibration signal and impulse response signal judgment technology are proposed. The PIND inspection technology is improved, which basically solves the misjudgment problem commonly found in PIND production inspection. Experiments show that the proposed shock response signal to determine the technology, but also can identify some specific cases of missing detection. This is of great significance for improving the reliability of aerospace products, and also has direct guidance on the revision of the PIND standard.
