【摘要】：為了研究不同類型元件組成系統(tǒng)后元件各自的維修率,同時考慮工作環(huán)境因素對維修率的影響,提出了元件維修率分布的概念。元件維修率分布是通過將SFT中故障概率分布代替Markov鏈中失效率實(shí)現(xiàn)的,給出了不同元件組成的并聯(lián)和串聯(lián)系統(tǒng)的元件維修率分布推導(dǎo)過程。實(shí)現(xiàn)維修率分布的計(jì)算關(guān)鍵在于狀態(tài)轉(zhuǎn)移概率p_0范圍的確定及不同元件故障率與維修率的比值,即為計(jì)算過程所需的限制條件,給出了p_0范圍和比例限定的計(jì)算方法和依據(jù)。對一個混聯(lián)系統(tǒng)進(jìn)行分析,說明了p0范圍依賴于系統(tǒng)結(jié)構(gòu)并計(jì)算得到0.087≤p_0≤0.625,也得到了系統(tǒng)中三個不同元件的維修率分布。
[Abstract]:In order to study the maintenance rate of different components in the system and consider the influence of working environment on the maintenance rate, the concept of component maintenance rate distribution is put forward. The component maintenance rate distribution is realized by replacing the failure rate in the Markov chain with the fault probability distribution in SFT. The derivation process of component maintenance rate distribution for parallel and series systems with different components is given. The key to realize the distribution of maintenance rate lies in the determination of the range of state transition probability and the ratio of failure rate to maintenance rate of different components, that is, the calculation method and basis for the limitation of the range and proportion of pStue 0 for the calculation process. An analysis of a hybrid system shows that the range of p0 depends on the structure of the system and calculates that 0.087 鈮，
