摘要:
小波变换可以对非稳态信号进行详细的时频分析,已广泛应用于机械、航空航天、土木等工程领域中,特别是在结构损伤识别和健康监测中的应用尤为突出.在第一代小波变换基础上提出的第二代小波变换,具有算法简单、运算速度快、能够准确匹配信号的局部特征等优点.笔者综合论述了第二代小渡变换理论及其在结构损伤检测中的应用,并对其未来发展进行展望.
Abstract:
Wavelet transform can conduct a detailed time—frequency analysis to non—steady—state signal and has been widely used in mechanical，aeronautical，civil engineering and so on．It is eonspicuous that wavelet analysis is applied in structural health monitoring and damage identification．The second generation wavelet transform had been raised on the basis of the first generation wavelet transform．It has much more advantages．Its algorithm is simple and the calculation is fast．It is able to suit fairly the partial feature of the signal and SO on．This paper reviewed and summed up the second generation wavelet transform theory and its application in structural damage identification．And its future development has been pointed out．
