摘要
针对传统GO法在分析具有共因失效、冷备等特征的可修系统可靠性时存在的不足,增设热储备门和冷储备门两个新操作符,给出其定量计算公式.基于改进的GO法并考虑C3列控系统的可维修性、共因失效、冗余等特征,在维修人员充足的条件下分析了其可靠性.研究表明:共因失效是可修系统可靠性分析的重要因素,不能忽略;与动态故障树法相比,GO法在可修系统可靠性分析中的效率更高,在空间和时间上优势更明显.
Hot spare gate and cold spare gate to two new operators and their calculation formulae are designed in GO methodology,in order to improve the traditional GO methodology,which does not work well in the reliability analysis of repairable system with common cause failures,cold standby and other factors.The reliability of C3on-board system is analyzed based on improved GO methodology.In our work,the maintainability,common cause failures,redundancy and other factors of the C3on-board system are considered,in terms of sufficient maintenance personnel.Research shows that the common cause failure factor is important in the reliability analysis of repairable system and can＇t be ignored.The improved GO methodology introduced in this paper is more efficient and economical at space and time than dynamic fault tree in the reliability analysis of repairable system.
