本篇論文利用廣義傳遞矩陣法（GTMM）結合Timoshenko樑理論，探討轉子系統於三度空間偏心分佈，分別推導出撓性軸、剛性圓盤及線性軸承之運動方程式，進而求得撓性軸、剛性圓盤與線性軸承之傳遞矩陣，再將撓性軸、剛性圓盤與線性軸承之傳遞矩陣組合成系統的傳遞矩陣。利用轉子系統之狀態變數，包括位移及角度，在兩相近轉速條件下，針對撓性軸及圓盤作偏心參數估計。論文內容包含了理論推導與電腦數值模擬等部分。

This research uses a general transfer matrix method （GTMM） and Timoshenko Principle for estimating the spatial unbalance parameters in rotor systems. Firstly we derive the motion equation of the flexible shaft, disks, and bearings. Through assembling the transfer matrices of the flexible shaft, disks, and bearings, we can obtain the global transfer matrix of the rotor system. The state variables of the transfer matrix include lateral deflections, deflection angles caused by shears and bending moments respectively, shears, bending moments, torque, and torsional angle. The spatial unbalance parameters of flexible shafts, and disk eccentricities, can be estimated at two closely rotating speeds. The theoretical development of the proposed method is presented with simulation results and discussion.
