摘要
文章首先讨论了含裂缝梁结构的柔度矩阵的变化;其次,通过选择不同模态振型函数进行小波变换分析,总结了不同模态振型在梁结构裂缝检测中的不同规律;最后,文章以悬臂梁为例,选用Gaus2小波对悬臂梁基本振型进行小波变换,进而对悬臂梁中的裂缝进行识别,裂缝深度与Lipschitz指数进行拟合。
The change of flexibility matrix contained in the crack beam structure is discussed; based on the wavelet-transform analysis with different mode shape functions, different rules of different mode shapes in the test of crack beam structure are summed up; wavelet transformation （with Gaus2 Wavelet） of the basic mode shape of a cantilever beam is carried out to detect cracks in the cantilever beam. The method presented here may also be used to detect cracks in other structures.
