基于小波变换的结构损伤检测

The structural destructive detection based on the wavelet transform

基于小波变换核心内容之一的多分辨分析,将小波变换应用于结构损伤检测中.实例分析表明,用损伤检测得到的回波信号的小波分解可排除噪声影响,准确地判定被检构件中损伤的空间位置.

Based on the wavelet transform multiresolution analysis, the authors apply wavelet transform to the structural destructive detection. Finally, it is shown from an example that the wavelet analysis of reflecting signal from destructive detection can decide the destructive place in detected element precisely, excluding the interference of noise.
