摘 要
本論文以修正傳遞矩陣法為理論依據，研發出轉子動力分析軟體(Rotor Dynamics Analysis,RDA)。因MS Visual Basic 6.0 ( VB6 ) 具視覺化開發環境、技術文件豐富及與其他軟體之搭配性高等優點。故RDA運用VB6建構出圖形化之輸出入介面。其所提供之分析功能包括轉子系統臨界轉速(critical speed )分析、固有頻率(natural frequency)分析、固有模態(mode shape)分析、失衡響應(unbalanced response)分析及渦旋軌道(whirling orbit)分析等。使用者可依設計需要選擇分析項目。RDA分析之操作特色為，只要輸入轉子系統各元件之資料與分析參數後，在欲分析之功能鈕上點選，RDA即自動選取該分析所需之參數進行計算，並將計算結果以數值及圖形顯示於視窗上，以供設計者比較參考。本研究所開發之RDA軟體具操作簡易且分析功能強大之優點，提供轉子動力研究者一個精確且有效之分析工具。

ABSTRACT
The research develops a rotor dynamic analysis (RDA) computer code. in which the theory of modified transfer matrix method is employed. Since MS Visual Basic 6.0 (VB6) has several advantages such as well-developed visual environments, numerous documentation and highly compatible with other softwares, RDA cooperates VB6 for the most friendly input and output interfaces to the user. The basic analyses provided by RDA consist critical speed, natural frequency, mode shape, unbalanced response and whirling orbit. The user can easily select what he/she needs from menu. It is as simple as just a click on user’s menu, and RDA does all the necessary work. The outputs are given in both numbers and graphs on windows for best realization. The RDA software developed in the research will prove to be powerful and efficient and it provides the rotor engineers as very precise and effective tool.
