摘要
在复杂系统故障关系分析中 ,为了准确、有效地描述系统状态条件同其故障关系间所存在的关联 ,提出了条件故障图的描述模型。界定并分析了描述系统状态关系的状态树 ,并将它与故障图相结合形成条件故障图。界定并分析了条件故障图的结构及其中的状态条件变化特性。将它应用于航空发动机的控制系统 ,并给出了一个特征实例。条件故障图可以有效地描述状态条件对故障关系的影响及作用 。
In order to exactly and effectively describe the relation between system condition and fault relation in analyzing fault relation of a complex system, a descriptive model of conditional trouble graph is presented. The state-tree of the system condition is combined with trouble graph to form a conditional trouble graph. The structure of the graph and the changing characteristics of the conditions are defined and analyzed, a characteristic example which was applied in the control system of an aeroengine is given. The graph can effectively describe the influence and effect of the condition on the fault relation, and is applicable to automatic description and analysis of fault relation.
