摘　　要：以200MW汽轮机转子为例用有限元方法建立了转子的动力学模型,介绍了轴系关键部件的简化,并给出了转子动力学模型图。所给出的汽轮机转子的动力学模型与实际结构十分吻合,对分析类似结构具有参考价值。The dynamic model of turbine rotor is created, and the critical speed and torsional frequency of a 200MW turbine rotor is analyzed by finite clement method （FEM）. The predigesting process on several key parts is introduced, and dynamic model figures of rotor arc given. The model arc same as structure of prototype rotor, and this is useful to analyze others similar structure.
