  1. To reduce the number of design variables, the sensitivity of both natural frequency and mode shape vector to component geometry parameters were derived respectively

    為優選設計變量，分別推導了固有頻率和振型矢量對其幾何參數的靈敏度公式。
  2. This system has a post - processing module which can generate natural mode shape

    系統還配有較強的后處理圖形生成模塊，可以形象逼真地繪制出振型圖。
  3. 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。
  4. These phenomena are roots of the unsteady excitation. ansys was used to solve the structure dynamic equations to obtain the natural frequency of vibration and mode shape of the blade

    本文應用工程軟體ansys完成了葉片的振型和自振頻率分析，結合數值計算得出的氣動激擾，進行了葉片的共振分析。
