中文摘要
9523316罗杰斯研究工作的目的是发展的基本科学方面的理解最近开发的定性非破坏性评估传感器系统。 我依靠跟踪结构的高频(通常为50 KHz)点时间来识别损坏。 在如此高的频率下,该技术在灵敏度上与最复杂的传统NDE技术(如超声波)相当,并且能够通过查看结构阻抗的变化来定性地检测早期类型的损伤。 这种技术克服了模型和“低频”无损检测方法的所有关键限制
英文摘要
9523316 Rogers The aim of the research effort is to develop an understanding of the fundamental scientific aspects of a recently developed qualitative non-destructive evaluation sensor systems. I relies on tracking the high-frequency(typically 50 KHz) pointimpedance of the structure to identify damange. At such high frequencies, the techniques such as comparable in sensitivity to the most sophisticated traditional NDE techniques such as ultrasonics and is capable of qualitiatively detecting incipient type damage by looking at changes in structural impedance. This technique overcomes all of the critical limitations of model and "low frequency" NDE approaches
