故障模式和影响分析 meaning in English
failure mode and effect analysis
Examples
- 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。 - A decision model of maintenance ways based on rcm logic analysis is established . then maintenance ways of equipments are made according to the result of failure mode effect analysis . finally maintenance interval is calculated and confirmed after the related algorithm is chosen according to the army ’ s practical application
