maximal amplitude meaning in English

最大振幅

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有限元分析软件，对系统进行了模态分析和动力学响应分析，获得了不同天线结构参数下的卫星?天线系统的固有特性，简谐响应的幅频特性，随机振动响应的功率谱密度，以及冲击响应的最大幅值和恢复时间等。
