摘要
GO法是一种适用于多状态、有时序的系统可靠性分析方法。传统GO法基于确定的概率值进行分析,而环境的模糊性和概率数据的不确定性会对事件发生的概率产生影响,因此将模糊理论与传统GO法相结合,可得到模糊GO法。以飞机主动侧杆系统为研究对象,在分析飞机主动杆系统结构特点基础上,构建了主动杆系统的模糊GO图模型,给出了计算飞机主动侧杆可靠性的模糊GO方法;然后采用传统GO法、故障树分析法(FTA)和模糊GO法分别对飞机主动杆进行可靠性分析计算。最后将模糊GO法和传统GO法及FTA法的计算结果进行对比,验证了模糊GO法在主动侧杆系统可靠性分析和安全评估中的可用性与正确性。
GO method is a reliability analysis method that is suitable for multi-states and sequential system.The traditional GO method is based on the analysis of the determined probability values,and the environmental fuzziness and the uncertainty of the probability data will affect the probability of the event.Therefore,the fuzzy theory is combined with the traditional GO method,and fuzzy GO method is put forward.This article takes the Active Side Stick(ASS)as the research object,the basic principle and analysis steps of fuzzy GO method are expounded,and the fuzzy GO model of ASS is constructed to calculate the reliability of the successful operation of the ASS.The reliability analysis and calculation of ASS is carried out by using the traditional GO method,the fault tree analysis(FTA)and the fuzzy GO method respectively.The results of fuzzy GO method,traditional GO method and FTA are compared to verify the usability and correctness of fuzzy GO method in the reliability analysis and safety evaluation of active side stick.
