摘要
采用连续小波变换的方法,在大型结构模态参数辨识方面提出了系统化的辨识流程,并对相近的频率所造成的辨识难点提出了解决的办法。通过三自由度模型模态参数的辨识,表明连续小波变换对于大型结构的模态参数辨识准确度高,具有现实意义。
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.
