| Abstract: | Modeling and modal analysis of an aero-engine rotor system were carried out with Pro/E and ANSYS to get the natural frequencies and mode shapes of first six orders and the calculation results were analyzed as well. Meanwhile, the results based on analysis of the design speed of the engine shows that this rotor system has enough safety margin of the vibration frequency and the resonance phenomenon would not appear within the running speeds of rotation. The present work also lays the foundation for further analysis of the rotor and provides an important theoretical basis for structural optimization design and dynamic performance improvements. |
