某型航空发动机常见振动故障分析

摘要

The structure of one aero-engine and the factors for vibration during fitting process were analyzed, and the common vibrating failures during production process were also analyzed including the rotor unbalance, the rotor unbalance as the rub-impacting, the rotor un-centering, the tubine rub-impacting and the equipment factors. Finally the diagnosing and debugging-aid methods for aero-engine vibrating failure were generalized.%针对某型发动机结构特点以及装配过程中与振动相关的要素,分析该型发动机生产过程中常见振动故障情况,包括转子不平衡、转子不平衡与转静件碰摩并发故障、转子不对中、高低压涡轮转/静件碰摩以及设备原因,总结了该型发动机常见振动故障诊断及排除方法.
