Stator structures of an large type integrally geared compressor are analyzed by finite element method through ANSYS in this paper. Many loads are applied to the model with appropriate methods, such as inner pressure, dead weight, forces and moments on inlet and outlet flanges, vibration excitations from rotor running, thermal loads, etc. Then, equivalent stresses and deformations about the whole model and key locations are extracted from analytical results. And the design proposal of compressor stator is proved to be reasonable and valid. Finally, based on the FEA results, some suggestions are proposed to get the optimal structural designing.
