| 摘 要： | 提出了两种反向旋转双转子系统的振动特性分析方法。基于MSC.NASTRAN大型有限元分析软件,开发了反向旋转双转子系统振动特性分析求解序列。利用两种方法,对某反向旋转双转子航空发动机转子系统的振动特性进行研究,并与传输矩阵方法及发动机整机试验结果进行对比。结果表明,两种方法对临界速度的分析结果正确,且对采用反向旋转方案的现代高推重比航空发动机的振动特性设计具有一定的参考价值。 |

| Abstract: | Two methods for vibration characteristic investigation of the counter-rotating dual-rotors in an aero-engine are put forward.The two methods use DAMP tool on the MSC.NASTRAN platform and develope the resolving sequence.Vibration characteristics of a turbofan engine are analyzed by using the two methods.Compared with results calculated using transfer matrix method and test results,the two methods are valuable and have great potential in practical applications for vibration characteristic investigation of aero-engines with high thrust-weight ratio. |
| Keywords: | aero-engine counter-rotating rotor dynamics dual-rotor vibration characteristics |
