航空发动机诊断系统数据融合研究

摘要

数据融合作为故障诊断学科中一门重要的手段,广泛地被用于科学研究,数据融合方法可以更好地检测本体的故障原因,并且为下一步诊断提供很好的科学依据。本文叙述了数据融合的原理和典型方法,介绍了国内外对航空发动机数据融合的研究发展概况,为日后运用于航空发动机故障数据的诊断和决策可行性做好了理论方面的准备。%As an important means of fault diagnosis discipline,data fusion is widely used in scientific researches.Data fusion method can detect better the cause of the malfunction in the body,and can provide corking scientific basis for the next diagnosis.This paper describes the principles and typical data fusion method,introduced domestic and foreign data fusion for aircraft engine research and development overview.Meanwhile,this paper is well prepared for the feasibility used in the data aero-engine fault diagnosis and decision.
