38526 最后以船用柴油机的并发故障诊断作为实例,验证了所提方法能够有效的诊断出并发故障并且模型具有较好的稳定性。 Finally with concurrent fault diagnosis of Marine diesel engine as an example, to verify the effectiveness of the proposed method can effectively diagnose the fault and concurrent model has good stability.
38527 动态故障树(dynamic fault tree,DFT)是对系统进行安全性分析的重要手段,基于马尔可夫链的DFT求解方法存在3个难题: Dynamic fault tree (dynamic fault tree, the DFT) is an important technique for system safety analysis, DFT algorithm based on markov chain exist three problems:
38528 一是仅可分析故障概率为指数分布的系统; one is only the analysis of the distribution of the failure probability of index system;
38529 二是无法分析共因失效情况; 2 it is to cannot be analyzed because of the failure situation;
38530 三是可能导致状态空间爆炸。 3 it is may result in the state space explosion.
38531 因此提出一种基于统计模型检测的DFT定量分析方法。 Therefore put forward a kind of DFT quantitative analysis method based on statistical model test.
38532 首先将DFT分解为动态逻辑门、基本构件、共因失效关系、门门和门构件间的逻辑关系; Will first DFT decomposition for the dynamic logic gates, basic components, common cause failure relationship, logical relationship between doors and door structure;
38533 其次将动态逻辑门、基本构件和共因失效关系基于随机混成自动机形式化规约; Secondly the dynamic logic gate, the relationship between the basic components and the common cause failure based on stochastic hybrid automata formal specifications;
38534 然后通过逻辑关系重构自动机,形成随机混成自动机网络; And then refactoring automata through logical relationship, form a random hybrid automaton network;
38535 最后通过分析一个具有共因失效关系的服从多失效概率分布的飞机结冰探测系统,表明所提方法的有效性。 Finally through the analysis of one who has a common due to the failure of the relationship between subject to many failure probability distribution of aircraft icing detection system, demonstrate the effectiveness of the proposed method.
