无损检测可靠性的定量表征技术

Quantifying Characterization of NDT Reliability

近年来由于飞机设计思想的变迁,使无损检测(NDT)的重要性大为增加,设计更有赖于NDT技术的有效性。通过损伤容限分析保证结构安全可靠的着重点在NDT系统能力的定量表征。本文论述了损伤容限分析中NDT的作用,检测概率曲线测定的方法和NDT可靠性定量表征技术的发展和应用。

In recent years, because of the changes in aircraft design concept, the importance of the role of NDT has been significantly increased, and the design more depands on the effectiveness of NDT. The guarantee of the structural safety through damage tolerance analysis has focused the attention on quantifying the capability of NDT systems. This article describes the role of NDT in damage tolerant design, the statistical determination of the flaw probability curve, and the application of NDT reliability quantifying characterization.
