angular vibration frequency 中文意思是什麼
angular vibration frequency
解釋
角向振動頻率-
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
該方法採用頻譜轉換法,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,最後對各位移分量進行疊加得到振動位移的時間歷程。
