基于灰色聚类分析的FJ44发动机故障诊断技术的研究

航空发动机故障诊断技术对于保证发动机的可靠性和飞行的安全性、经济行具有重要意义。本文以FJ44型航空发动机为研究对象,采用灰色系统理论对发动机常见故障类型进行分析,通过灰色聚类分析的方法实现发动机常见故障的诊断。实际参数验证表明该方法具有较高的可行性,对FJ44型发动机的故障诊断有一定的参考性。

The aeroengine fault diagnosis technology have very important meaning to guarantee the reliability,safety and economic of the engine and flight. This paper take FJ44 aeroengine as the research object,by using the grey system theory to analyze the common faults of this engine.through the method of gray clustering analysis to realize the engine common fault diagnosis.The actual parameters test show that this method has a highly feasibility,and it can be a certain reference for the FJ44 aeroengine fault diagnosis.
