摘要：
Based on the hydrodynamics, the airflow exciting_vibration force of control stage of steam turbine is studied by using the momentum theorem. A formulation for calculating the air exciting_vibration force of the control stage of steam turbine is deduced first by using theoretical analysis method and taking all the design factors of vane and nozzles into consideration. Moreover, the exciting_vibration forces in different load cases are discussed respectively.
