Based on frequency - spectrum - transformation , this algorithm first changes acceleration spectrum into displacement spectrum , then calculates its amplitude , angular frequency and initial angle related to every displacement spectrum , finally sums up all the displacement components and forms the time course of the measured vibration 該方法采用頻譜轉換法,首先將加速度譜轉換成位移譜,再計算出位移譜中每個頻率分量對應的幅值、圓頻率和初相角,最后對各位移分量進行疊加得到振動位移的時間歷程。
