摘要
为提高结构损伤识别方法的准确性和适用性,将小波分析引入到结构损伤识别中。本文首先介绍了小波分析的基本原理,然后详细论述了小波分析用于结构损伤识别的三种方法:基于时域响应的方法、基于空间域响应的方法和小波分析与其他方法联合使用,接着分析了各种方法的应用现状、适用范围和存在的问题。通过比较可以看出小波分析用于结构损伤识别有着广阔的应用前景,本文最后针对进一步研究的方向提出了五点建议。
For comfirming the validity and applicability of structural damage identification methods, wavelet analysis is used to structure damage detection. On the basis of the theory of wavelet analysis, three methods of structural damage identification, which include time-domain response based methods, space-domain response based methods and other methods combined with wavelet analysis, are discussed in detail. Subsequently, application state, application range and existent problems of diversified methods are analyzed. Through comparison with other methods, it is obvious that the method taking wavelet analysis into structural damage identification is promising. Finally, five advices to the further research direction are put forward in this paper.
