1. We acquired the system ' s dynamic response when the satellite attitude was adjusted and the mode of the antenna . then modal analysis and dynamic analysis have been done to the satellite - antenna system by using the finite element analysis ( fea ) software of ansys . through the analysis we got the system ' s connatural characteristic , the amplitude - frequency characteristic of harmonic response , the power spectrum density of random vibration response , the maximal amplitude and resuming time of impact response
   其次借助ansys有限元分析軟件，對(duì)系統(tǒng)進(jìn)行了模態(tài)分析和動(dòng)力學(xué)響應(yīng)分析，獲得了不同天線結(jié)構(gòu)參數(shù)下的衛(wèi)星?天線系統(tǒng)的固有特性，簡(jiǎn)諧響應(yīng)的幅頻特性，隨機(jī)振動(dòng)響應(yīng)的功率譜密度，以及沖擊響應(yīng)的最大幅值和恢復(fù)時(shí)間等。
2. It's difficult to find maximal amplitude in a sentence. 用maximal amplitude造句挺難的
