  1. The results of this work are valid for under - damping modes provided that the sampling rate is sufficiently higher than the natural frequencies of interest

    本文提出的理論解在假設取樣高於數倍以上時可適用於所有次的模組,因此較過去的研究結果更為完整。
  2. Then, the hilbert transform is applied to each modal response to obtain the instantaneous amplitude and phase angle time histories. a linear least - square fit procedure is proposed to identify the natural frequency, damping ratios, physical mass, damping and stiffness matrices from instantaneous amplitude and phase angle for each modal response

    後對各階模態響應進行hilbert變換,得到瞬態幅值和相位角的時間歷程,再運用線性最小均方擬合來識別比、質量、剛度和矩陣。
