碩士 === 國立中山大學 === 機械工程研究所 === 86 === 　　The dynamic responses of a high speed rotating thin disk under a harmonic traveling excitation has been formulated and investigated ing this thesis. The disk is clamped near the core and is free at the perimeter. A harmonic traveling transverse load in arc path is employed to simulate the external excitaton. The motion of the excitation point is approxmated by a constant accelerate-declerate motion. By using the Galerkin method, the governing equations of a spinning disk in an inertia frame can be obtained. The natural frequencies, natrual modes and dynamic response of this disk can then be solved, The effects of rotating speed, disk dimension and the way of traveling load on this disk system are analyzed in this investigation.
