- Abstract
In order to obtain the steam turbine generator rotor inherent frequency, the critical speed and numerical control processing method, 3-D software Pro/E of NC machining function and the finite ele-ment analysis software ANSYS are used to the steam turbine generator rotor bending vibration of natural frequencies and critical speed were calculated by the 20 order frequency, so as to avoid the critical speed work the same produce resonance phenomenon, achieve the optimized rotor dynamic characteristics of the target. PRO/E processing simulation function was used to realize the shaft turning processing and milling simulation, the actual rotor model for NC machining the necessary basic lay.
