摘要
Abstract
A systematic study of the method of selecting scales in wavelet transform for damping identification in frequency domain was carried out. A method to select the scale with the modulus at the maximum was developed by extending the range of scales, it is proved that using this method in small damping ratio and linear system,we can achieve better results in identification of the closely-spaced model.关键词
