部件模态 meaning in Chinese

part modality

The model coordinate of the flexible appendage added to the system is the reason that cause the order of the system too high
用部件模态坐标表示柔性部件的弹性变形的引入是导致模型高阶的主要原因。
This paper combines the experimental modal analysis technique with the techniques of analytic modal and component modal synthesis ( i . e . external superelement analysis ) provided by msc / nastran to obtain the modal parameters of complex structures . it mainly researches the process of external superelement analysis , required important sentences in msc / nastran and the method inputting modal test results . a t - kind structure and an aircraft mode , as examples , are researched through experimental modal analysis and component modal synthesis
本文的工作重点是将试验模态分析技术与msc / nastran中的解析模态计算和部件模态综合技术结合起来去解决工程实际问题，着重探索了msc / nastran中外部超单元分析的过程和重要语句，以及模态试验数据的输入等问题，并以一个t型结构和某型飞机全机模型为例做了部件模态综合计算。
