Abstract:	本篇論文提出轉子軸承系統軸承參數的估計方法，所考慮的系統是由撓性軸、剛性圓盤、以及線性軸承所組成，特別的是撓性軸之圓截面是可沿著軸向分段改變。隨著撓性軸可獲得資訊不同，軸承參數之估計方法亦有不同，本篇論文針對：(1)撓性軸相鄰支撐部分之軸元素參數全部已知；(2)撓性軸相鄰支撐部分軸元素之剛性未知，其餘已知，二種情況分別加以討論。除此之外也考慮量測誤差對參數估計的影響。本篇論文最主要特色是只需量測單一旋轉速度的響應，且不需要量測系統激振力，即可估計軸承的八個參數。論文中包含了有限元素模型理論、軸承參數之估計 This research presents a new method based on the finite element model for estimating linearized characteristics of bearings in rotor-bearing systems including the flexible shaft, which may be changed stepwise along the axial direction, rigid disks, and li
