摘　　要：高速汽轮发电机转子的临界转速是汽轮发电机转子设计中的一个重要参数,随着计算机技术的不断发展,使得能够全面考虑影响汽轮发电机转子临界转速因素,计算结果更接近于实际的有限元分析法的应用将会越来越广泛。文章详细介绍了利用ANSYS有限元软件的模态分析功能,计算汽轮发电机转子临界转速的方法和计算结果的后处理过程。The critical speed of high-speed turbine generator is a main parameter in design of rotor, it has many computing methods such as classical theoretical method, energy method, decomposition iterative method and transmission matrix method, etc. Along the development of computer technology, the factors, which influence the critical speed of turbine generator, can be considered fully, and the finite-element analysis method, the calculation values of which approach to actual values, will be applied widely. This paper introduces the simulation state analysis function of ANSYS software, calculation methods of critical speed of turbine generator rotor and post-treatment process of computing results in detail.
