结构损伤动力识别技术的研究与进展

Researches and Advances in Structural Damage Dynamic Identification Technology

通过对结构损伤的动力识别技术近二十年来国内外研究成果的总结,阐述了结构损伤动力识别研究的发展历程。首先介绍了结构损伤动力识别技术的基本原理,然后从三个方面,即结构损伤的动力识别机理、结构损伤的动力识别参数和结构损伤的识别算法,分别探讨了结构损伤动力识别技术的发展现状和面临的问题,最后对结构损伤动力识别的未来研究趋势进行了展望。

This paper describes the theory and research progress of dynamic structural damage identification technique of the last twenty years. The basic theory of dynamic structural damage identification techniques is introduced first. Next, three important aspects of damage identification are discussed： identification mechanisms, dynamic parameters, and identification algorithms. Finally, a review of the state-of-the-art and development trends in this field is presented.
