碩士 === 國立成功大學 === 航空太空工程學系碩博士班 === 100 === In this thesis studies the dynamic response of an Elastically Supported Spinning Beam Subjected to a Moving Load. Firstly, this study simulates the Timoshenko beam, subject is under a moving force along the axial, this study uses the finite element method to construct the model, then uses the Lagrangian approach to derive the equations of motion, using the Runge-Kutta method to solve the dynamic response of the spinning system, and then we discuss stiffness coefficient, the speed of moving load, shaft whirl speed that may affect the system dynamic response. According to the numerical results system vibration and the moving load speed have great relevance, when the speed of the moving load is reduced, the smaller the vibration is.
