本論文主要以分佈參數及離散參數模式探討轉子系統之動態響應及振動
控制.首先應用Rayleigh樑理論並包含轉動慣量及陀螺效應.以探討旋轉軸
在六種邊界條件下之動態反應,其迴轉速度(whirl speed)之解析解可以用
兩個無因次化參數表示,一是迴轉比(whirl ratio),另一是細長比(
slendernessratio).理論分析發現,當迴轉比大於1/2時,系統所能激發出
的模態是有限個.此結果可以應用於不平衡響應的求解及其振動控制.對於
控制器設計時,殘餘模態之溢出不穩定問題亦可完全去除.本文亦針對離散
參數模式轉子系統,提出一簡易控制器設計法則.此法結合實驗設計法的性
能強健性及傳統PD控制的易實現性,將感測器,致動器的位置及回饋增益值
當設計參數,透過少數的直交表實驗,便可決定其最佳值,以避免繁雜嘗試
錯誤過程.同時針對同置型及非同置型系統作性能分析,其結果顯示此法不
僅簡單,並可同時有效地 抑制操作範圍內的振動響應.
The dynamics and vibration of rotating systems are of
fundamentalimportance in the design of rotating machinery. In
order to preventfrom excessive vibration, analyses of the
natural frequencies,commonly called the whirl speeds, and mode
shapes are required inpredicting the resonant and forced
responses. In particular, thesynchronous whirl speed, also
called the critical speed, is ofprimary concern because the
unbalanced excitation is synchronouswith the rotating speed.
Dynamics and control of rotor systems bothin distributed and
discrete parameter models are studied in thisdissertation. A
controller design methodology forvibration suppression is
developed in discrete parameter model. Themethodology combines
the experimental design method in qualitycontrol engineering and
the conventional PD control technique suchthat their advantages
in implementation feasibility and performancerobustness can be
integrated together. By using the location of thesensor/actuator
and PD feedback gains as the design variables, thecontroller can
be determined by a small number of matrix experimentsto achieve
best system performance.
