superelement method 中文意思是什麼
-
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
本文的工作重點是將試驗模態分析技術與msc / nastran中的解析模態計算和部件模態綜合技術結合起來去解決工程實際問題，著重探索了msc / nastran中外部超單元分析的過程和重要語句，以及模態試驗數據的輸入等問題，並以一個t型結構和某型飛機全機模型為例做了部件模態綜合計算。
