摘要
针对由三个不同部件,一个完全可靠的开关和一个修理设备组成的温贮备可修系统,建立了部件的工作寿命,贮备寿命,工作故障后的修理时间和贮备故障后的修理时间均服从不同参数的指数分布的数学模型,利用Markov型可修系统的研究方法,并采用MATLAB软件给出了该系统的首次故障前的平均时间、可用度和故障频率等可靠性指标的表达式.
A reliability analysis of three different components warm standby repairable systems with a completely reliable switch and a repair equipment sets up mathematic model that service life of components, shelf-life repair time after the breakdown and standby fault were all subjected to different types of exponential distribution. With the help of the research method which is based on Markov repairable system and MATLAB software, the expressions of the average time before the first failure, availability, fault frequency and other reliability indicators are obtained.
