遞矩陣法將系統分解成若干可撓性軸, 剛性圓盤, 軸承支撐等組成單元,
並建立其轉移矩陣. 本文擴充傳遞矩陣法推導得對心失準之傳遞矩陣, 並

振幅與渦旋軌道之變化情況.

This research employs the modified transfer matrix method to
investigate the rotor dynamic behavior with misalign occurrence.
The traditional transfer matrix method divides the rotor systems
into several types of segments such as flexible shaft, rigid
disk, elastic support and build up the corresponding transfer
matrices. The present reseach extened that method to include the
transfer matrix of shaft misalign. The effects of parameters due
to misalign are there looked into and discussed extensively.
Critical speeds and steady response due to misalign are
particularly focused on. At last, the combined effects of disk
imbalance and shaft misalign are studied. Response amplitude as
well as whirl orbit are there discussed.
