| 中文摘要: |
| 为解决航空发动机整机振动问题，根据测试结果描述了航空发动机整机振动的3种典型故障：转子热弯曲引发的振动故障、转静子碰摩引发的振动故障和甩油孔位置不当引发的自激振动故障，说明了振动故障的特征，经分析认为故障发生的原因为甩油孔位置不当引发的自激振动，给出了排除上述故障的措施，经验证，排故效果良好，证明了采用的排故措施有效。 |
| 英文摘要: |
| To solve the aeroergine vibration failures, three typical failure of aeroengine vibration were concluded by the texting results. The vibration failures caused by the thermal bowed rotor, rotor-stator rub interaction and out of position for oil hole. The characteristic of vibration failure was illustrated. The reason is self-exciting vibration caused by the out of position for oil hole. The good failure elimination result proves that the methods are valid |
