| 摘 要： | 小波包分析损伤识别方法首先将结构响应信号分解为小波包组分,然后通过各组分小波信号的变化情况识别损伤。通过3层框架结构的数值分析,模拟结构损伤,判断损伤时刻与损伤位置。分析小波组分信号突变情况,可以识别损伤时刻、损伤位置和损伤程度。

| Abstract: | In wavelet packet analysis,the structure response signal is decompounded into wavelet packet components,and then damage is identified by observing the changing of the wavelet packet components.Through one three-layer frame structure digital simulation,structure damage is realized,and the damage time and position is got.Observing wavelet packet components changing can make us know damage time,location and damage degree. |

| Keywords: | time-frequency analysis wavelet transform wavelet packet analysis structural damage identification |
