本文之主旨在於利用有限元素法(finite element method:FEM)來探討由軸、圓盤與軸承所構成的轉子系統之自然頻率及強迫振動反應。文中首先利用有限元素法來推導軸、圓盤及軸承等三種元素的運動方程式,然後將上述三種元素之質量矩陣、阻尼矩陣、勁度矩陣與不平衡力(或外施負荷)加以組合,而求得整個轉子系統運動方程式,解之則得轉子系統在(偏心)不平衡力作用下之強迫振動反應,若令不平衡力(外施負荷)向量等於零,而解特徵值問題,則可求得轉子系統的自然頻率。有關於轉動慣性 (rotatory inertia)、迴轉力矩(gyroscopic moments)以及軸向負荷等效應,本文均納入考慮。旋轉軸所受軸向力以及圓盤的偏心距對轉子系統動態反應的影響,係本文研究的重點。
