| Summary: | 碩士 === 中華大學 === 機械與航太工程研究所 === 93 === A finite element dynamic model for the coupled torsional and lateral vibrations of a symmetric rotor-bearing system is developed. The rotor-bearing system includes the flexible shaft, which may be changed stepwise along the axial direction, rigid disks, and linearized bearings. The equations of motion, obtained using Hamilton’s principle, showed nonlinear interaction between the rotor torsional and lateral vibrations. The nonlinear numerical method is introduced and the equivalent mass, damping, and stiffness matrices of the nonlinear motion equations are investigated for the purpose of numerical simulation in the future.
