开关寿命连续性两不同部件温贮备可修系统可靠性分析

S M劳斯对有两个同型部件构成的开关寿命为连续性随机变量的温贮备可修系统的可靠性进行了分析,在此基础上本文对由两个不同型部件构成的、开关寿命为连续性随机变量且开关失效系统立即失效的温贮备可修系统,在两部件的工作时间和维修时间以及转换开关的寿命和修理时间均服从指数分布、所有随机变量均相互独立、工作部件的寿命分布与其贮备时间无关、故障部件和转换开关均可修复如新的条件下作了可靠性分析,不仅给出了系统的可靠度、首次故障前平均时间的结果,还给出了各项稳态的可靠性指标的解析表达式.

Reliability analysis of warm nonmaintained redundant of two different components repairable system with continuous lifetime switch

S M Ross presents a reliability analysis of the warm nonmaintained two components redundant repairable systems with continuous lifetime switch. Based on the paper, the reliability analysis of the warm nonmaintained repairable systems of two different components with continuous lifetime switch is presented in this paper. Under the condition that the operating time and maintained time of two components and the lifetime and repair-time of switch are all exponential distributions. And the systems fail if the switch fails. All the variables are independent, and the lifetime of operating components have nothing to do with its maintained time, and the failure components and switch can be as good as new after repair. In this paper the reliability R(t), the mean time to failure MTTFF and other steady-state reliability indexes are obtained.
