摘　　要：智能故障诊断技术是一种新的故障分析方法,它更为注重从系统整体结构来考虑故障发生的原因以及故障之间的传导关系。基于结构及行为的诊断是智能诊断发展的一个新突破,是一种基于模型的诊断(MBD,Model-Based Diagnosis)。深入研究了模型建立、诊断产生和诊断测试的方法,实现了一个可以应用到生产实际的诊断系统,并应用于柴油发动机进气系统的故障诊断中。Intelligent Technique of Fault Diagnosis is a new fault analysis, which pays more attention to doing research on the overall structure of the system and transmission relationship between the different faults. Structure and behavior-based diagnosis is a thought breakthrough in the intelligent diagnosis. It is a kind of model-based diagnosis. Modeling, diagnostic generation and diagnostic tests are studied in depth and a diagnostic system which can be applied to the actual production system is brought out. Then it is applied to the fault diagnosis of the intake system of diesel engine.
