摘要
针对共因失效使系统可靠性分析复杂化的问题,提出基于成功流(GO)法的共因失效可靠性Simulink仿真方法。在构建共因集GO模型时,考虑共因失效的影响。运用累积概率法进行定量计算,并构建共因集Simulink模型,利用仿真工具降低建模、计算的难度。经算例验证,改进仿真方法较传统计算方法更为简单,Simulink在共因失效可靠性GO法分析中具有可行性与有效性。
Common Cause Failure（CCF） makes the reliability analysis more complex. The Simulink simulation method of CCF reliability analysis based on Goal Orient（GO） methodology is put forward. The GO model of Common Cause Group（CCG） is presented with importing CCF. The cumulative probability algorithm is used for quantification calculate. The simulink model of CCG is presented for making modeling and calculating easier. An example shows that the improved method is more simple than the traditional calculation methods. Simulink has feasibility and validity in reliability GO analysis method of CCF.
