failure tree analysis meaning in English
故障树分析
Examples
- Four major failure modes for high arch dams , namely destabilization dam lost stability failure , shearing - slipping failure , excess cracking and man - caused destruction , are presented by means of failure tree analysis
摘要利用故障树分析法得出了高拱坝具有失稳溃坝、剪滑垮坝、超量开裂及毁坝等4种主要失效模式。 - A lot of papers about the report of probabilistic risk assessment of daya bay npp and system manuals has been read by the author and let as the basis . in this paper , based on the reliability analysis methods of failure mode and effect analysis and failure tree analysis , according to the result of event tree analysis of probabilistic risk assessment report of daya bay npp , the top events of the fault trees of reactor protection system and the success criteria were established . by using risk - spectrum procedure , the unavailability and the minimal cut - sets ( mcs ) of the fault trees were obtained
本文在阅读了大量的大亚湾核电站pra报告和各种系统手册等资料的基础上，采用fmea (故障模式和影响分析)和fta (故障树分析)可靠性分析方法，依据大亚湾核电站pra事件树分析的结果，建立了以紧急停堆失效和专设安全设施驱动失效为顶事件的故障树，利用risk - spectrum程序，对所建的故障树进行定量分析，计算，得到系统故障树的失效概率和最小割集，从而为大亚湾核电站可视化风险分析软件提供数据支持。 - Based on the malfunction datum of 328 power transformers ( 110kv or above ) , the paper makes the following studies by both the analysis of the datum and lots of tentative tests and presents the corresponding research results : the research on the malfunction mode classification of power transformers by the failure tree analysis method ( fta ) ; the research on the status prediction criterion of running power transformer ; the research on detective methods and criterions of the disability of the power transformer ; the research on evaluation the life of the power transformer ; the research on the relationship between the status estimate system and status examination & repair of the power transformer
