摘要
为了对系统的可靠性进行自动化分析 ,本文在两个方面发展了进行故障系统描述的故障传递表模型 :( 1 )对故障传递表的格式进行了较大改进 ;( 2 )提出了能流故障类 ,以它为故障传递表描述的补充。采用这种改进的模型可方便地对系统进行多模态及复杂的故障关联描述。将模型应用于航空发动机液压机械控制系统的描述 ,并自动建造故障树 ,取得了较好的效果。
In order to analyze the systematic reliability automatically,a model of fault transfer table for describing fault system is developed in two aspects:(1)the format of fault transfer table is improved obviously;(2)the energy flow fault class is put forward so as to supplement the fault transfer table.Using this ameliorated model,multi mode and complicated fault conjunctions can be described expediently.This model has been applied to fault description of an aeroengine hydraulic mechanical control system,and the fault tree has been built automatically,in result a success has been reached.
