| Abstract: | Based on continuous wavelet transform method, systematic identification process is proposed for the large- scale structure of the modal parameter identification. The solution is introduced for the difficulty caused by the similar frequency identification. The identification results of the 3-DOF model parameters show that the continuous wavelet transform has high accuracy for the modal parameter identification of the large-scale structure. |
