The frequencyresponse function and the power spectrum function for stationary and non-stationary inputs are obtained.
求出了频率响应函数以及输入为平稳和非平稳情况下的功率谱函数。

We can get frequencyresponse, power spectrum density (PSD), modal coordinates, etc. by modal analysis module of ADAMS.
利用ADAMS做模态分析，可以求得频率响应、功率谱密度(PSD)、模态坐标等信息。

The feature that structures have the selectivity to the earthquake motions frequency and structure response has the close corresponding relation with instantaneous energy spectrum is pointed out.
