| 摘 要： | 运用小波包能量法对完好的和具有损伤的简支梁进行数值模拟，施加相同的激励，测得结构的响应信号，对信号进行小波包分解，求得各个频段的能量，通过各频段能量的变化进行损伤位置的识别，指出这种方法可以对实际梁结构进行有效的损伤诊断。

| Abstract: | The author gets numerical simulation on intact and damage simply supported beam based on the wavelet-packet energy method,imposes same incentive,gets the structural response signal,gets wavelet-packet decomposition on the signal,and solves the energy in all bands,based on the change of the energy in all banes recognizes the damage situations,points out that this method can gets effective damage diagnosis on practical beam structure. |
