| Abstract: | The vibration characteristic of the rotor blade for some type low compressor have been computed and analyzed by means of a optimized eight nodes over parameters finite element. With combine the rotor structure and the working state of aero-engine the potential and dangerous resonance have been analyzed deeply. We find the performance of resisting vibration is not good. It also provides the importance basis to monitoring in site and fault forecast. |
| Keywords: | Compressor Vibration characteristic Finite element method Resonance analysis |
