摘要:

结构健康监测(SHM)方法的工程应用已越来越广泛,在航空航天领域的应用也逐步展开,但如何评价其可靠性仍然没有形成广泛认可的标准。近年来学术界和工业界围绕如何发展SHM可靠性评价方法方面做出了诸多探索,无损检测(NDT)可靠性评价方法已被用作SHM可靠性评价研究的起点,然而SHM无论是系统实现还是应用模式都和NDT具有明显区别,SHM的可靠性评价还有待深入研究。综述了从NDT到SHM的可靠性评价方法的研究及发展现状,结合研究现状讨论了NDT可靠性评价方法的发展、NDT可靠性评价方法在SHM上的应用,SHM和NDT可靠性评价的差异,SHM可靠性评价方法的发展,并在此基础上,提出了基于条件控制的SHM双可靠性评价方法,并进行了总结与展望。

Abstract:

The engineering applications of Structural Health Monitoring (SHM) methods have become more and more popular, and their application in the aerospace field has been gradually developed. However, but there is still no widely recognized standard on how to evaluate their reliability. In recent years, both academia and industry have made many explorations on how to develop SHM reliability evaluation methods, and the Non-Destructive Testing (NDT) reliability evaluation method has been used as a starting point for SHM reliability evaluation. However, SHM is significantly different from NDT both in terms of system realization and application mode, and the reliability evaluation of SHM has yet to be thoroughly studied. This paper reviews the reliability evaluation methods from NDT to SHM. The development of NDT reliability evaluation method, the application of NDT evaluation method on SHM, the difference between SHM and NDT reliability evaluation, and the development of the SHM reliability evaluation method are discussed with the current research status. Based on this, a condition control-based dual-reliability evaluation for SHM is proposed, and concludes with a summary and prospect.

Key words: reliability evaluation, structural health monitoring, non-destructive testing, condition control, accuracy and uncertainty evaluation, evaluation data sources
