碩士 === 國防大學中正理工學院 === 造船工程研究所 === 93 === The subject of this paper is to analyze the vibrating characteristics of rotor-bearing system by using the Transfer Matrix Method (TMM), which natural frequencies, mode shapes, critical speeds, and unbalanced responses are included. Furthermore, the load sensitivity matrix and elevation sensitivity matrix of bearing load distribution in multi-support rotor-bearing systems are deduced by using the TMM. The responses of bearing loads in variable bearing elevations and loads are analyzed through the sensitivity matrix to further prevent the related breakdown occurrence. In addition, the influence of the overall rotor - bearing system with the rigid disk which is laid aside to the different positions and supporting stiffness is discussed in this paper. Thus, the basis of structural design and the installment adjustment of the overall rotor - bearing system can be achieved.
