摘要
混合诊断模型(HDM)是相关性诊断模型的一个扩展,它将功能模型和故障模式模型建立在一个系统模型中.本文对混合诊断模型中的诊断推理规则进行了研究,并提出了基于故障模式和基于功能的混合诊断推理,同时具体细化为五种不同的推理规则.同时对混合诊断模型的建模推理过程进行了详细的描述,明确了功能和故障模式故障率之间的关系.经过实验证明,混合诊断模型是一种适合于故障分析的有效的模型,将该模型应用与我们的装备故障分析中是可行、有效的.
Hybrid diagnostic model （HDM） is an extension of diagnostic dependency model, it is a model whlcla makes function and failure mode model into one system model. This paper studied the hybrid diagnostic inference rules in the model, and proposed the hybrid diagnosis reasoning based on the failure mode and function, and the specific divided into five different inference rules. The modeling of hybrid diagnosis model reasoning process has carried on the detailed description, maked the relationship between the failure rate function and fault patterns clear. The experiments showed that a hybrid diagnostic model is a kind of effective model is suitable for fault analysis, applying the model to our equipment fault analysis is feasible and effective.
