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
