actual measurement indicates that the displacement and acceleration of rail vibration both have random property, the displacement spectrum mostly has obvious low frequency contets which occupy dominant peak value range
實測表明,軌道振動的位移和加速度都具有隨機(jī)特性,位移頻譜組成以低階頻率為主,且有明顯占優(yōu)勢的峰值區(qū)域。
b ) relative velocity response spectrum ( sv ) and relative displacement response spectrum ( sd ) : the variation of velocity spectrum with depth is similar to that of acceleration spectrum . but the variation of displacement spectrum with depth is a little different to that of acceleration and velocity spectrum . that is, in strong earthquake, the variation of displacement spectrum and normalized spectrum in different depth is very small
(2)速度反應(yīng)譜(s、)和位移反應(yīng)譜(sd)沿深度變化的規(guī)律速度反應(yīng)譜沿深度變化的特點與加速度反應(yīng)譜基本相似;位移反應(yīng)譜沿深度變化的特點與加速度和速度反應(yīng)譜有較小差別，即強(qiáng)震時位移反應(yīng)譜和標(biāo)準(zhǔn)位移反應(yīng)譜沿深度的變化很小。

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(zhuǎn)換法，首先將加速度譜轉(zhuǎn)換成位移譜，再計算出位移譜中每個頻率分量對應(yīng)的幅值、圓頻率和初相角，最后對各位移分量進(jìn)行疊加得到振動位移的時間歷程。
