Therefore, through structural modal analysis with different damage degree using ANSYS, get natural frequencies and mode shape data as neural network input vector after unitary.
因此，通过有限元软件ANSYS对具有各种损伤程度的结构进行模态分析，得到固有频率和模态分量的数据，经过归一化处理后作为神经网络的输入向量。
The sine steady circuit is analysed by means of vector mode. If the vector mode is flexibly used as the auxiliary tool in the analysis, it will provide simple way to solve the problem.
正弦稳态电路分析往往要采用相量法，在分析过程中若能灵活运用相量图为辅助工具，则能为问题的解决提供简洁的思路。
