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
