| Abstract: | To aim at the problem of a 3MW turbo-generator＇s stator resonance, a modal simulation has been done to analyze the stator frame on NX platform, so as to get natural frequency and corresponding modes of vibration of different orders. The hammer excitation method has been used to test the stator frame, and got the response spectrums of the frame, which were in well agreement with the results of the simulation. The validity of the finite element model and finite modal analysis were verified. |
