  1. Firstly, frequencies of each mode shape are gained through frequency spectrum analysis of time domain signals of key points. secondly, time domain signals, which correspond to structural mode shapes, are gained through band - pass filter technology. lastly, the corresponding mode shapes of each natural frequency are constructed by using time domain signals, which are processed by band - pass filter technology

    該方法的基本思想是先通過對關鍵點處時域信號進行譜分析得到結構各階振型對應的固有頻率，然後通過帶通濾波技術得到結構關鍵點在每階固有頻率下對應的時域信號，最後用濾波后時域信號構建結構在每階固有頻率下對應的振型。
