  • For reducing 3-D finite element rotor model, rotating substructure method, a reduction method easy to operate which was derived from the basic principle of Guyan reduction method and analysis theory of rotor dynamics was presented, and it could be practically used by ANSYS program. 21% degrees of freedom of a turbofan engine rotor model was reduced by this method. The maximum percent error of the first 20 order natural frequencies of reduced model is 0.43% and all the modal assurance criterion are 1 except that of the 17th mode of vibration of 0.98. The maximum critical rotating speed error is 0.46%. All the results show that the proposed method is valid.
