主 题:k-out-of-n system load-sharing effect failure mechanism propagation damage factor model combinational algorithm
摘 要:In complex systems,functional dependency and physical dependency may have a coupling *** this paper,the reliability of a k-out-of-n system is analyzed considering load-sharing effect and failure mechanism(FM)*** types of FMs are considered and an accumulative damage model is proposed to illustrate the system behavior of the k-out-of-n system and the coupling effect between load-sharing effect and FM propagation effect.A combinational algorithm based on Binary decision diagram(BDD)and Monte-Carlo simulation is presented to evaluate the complex system behavior and reliability of the k-out-of-n system.A current stabilizing system that consists of a 3-out-of-6 subsystem with FM propagation effect is presented as a case to illustrate the complex behavior and to verify the applicability of the proposed *** to the coupling effect change,the main mechanism and failure mode will be changed,and the system lifetime is *** are analyzed and results show that different sensitivity factors of three different FMs lead to the change of the development rate,thus changing the failure *** the coupling effect may lead to an incomplete and ineffective measuring and monitoring *** strategies must be adopted to make the FM propagation insensitive to load-sharing effect.
