| Summary: | 碩士 === 國立成功大學 === 航空太空工程學系碩博士班 === 101 === In this thesis, dynamic response of a two-stage epicyclic gear train is analyzed by using the finite element method, and numerical results are obtained by the Runge-Kutta method. Sun gear, planetary gear, and planet carrier of the system are considered to be rigid. Rotating shafts are modeled as Timoshenko beams. Bearings are considered to be linear and modeled as spring-damper sets. The effects of the planetary shaft with or without bearing support on the dynamic response of the system are investigated. The bearing forces and natural frequencies of the system are calculated. Numerical results of this research show that if the planetary shaft is supported by a bearing, the displacement response of the system and the bearing force are reduced, and the natural frequencies of the system increase.
