多状态串并联系统的性能和状态取决于其组件间的结构形式及组件不同状态的组合,为对其可靠性进行有效的评估,基于多状态系统理论和概率论提出了一种多状态串并联系统状态及工作性能的定量分析方法。分别建立了多状态串联系统、并联系统和串并联系统在不同状态下的等同集,依据其性能水平对等同集进行划分,在此基础上建立了各状态下的平均加权性能水平和状态概率的计算模型,并给出了多状态串并联系统平均性能的计算方法。构建了基于系统性能与状态分析的评估与维修决策框架。以全悬挂转炉倾动装置二级减速机多状态串并联系统的工作性能分析为例,对建立的分析模型的有效性和可行性进行了验证。
多狀態串併聯繫統的性能和狀態取決于其組件間的結構形式及組件不同狀態的組閤,為對其可靠性進行有效的評估,基于多狀態繫統理論和概率論提齣瞭一種多狀態串併聯繫統狀態及工作性能的定量分析方法。分彆建立瞭多狀態串聯繫統、併聯繫統和串併聯繫統在不同狀態下的等同集,依據其性能水平對等同集進行劃分,在此基礎上建立瞭各狀態下的平均加權性能水平和狀態概率的計算模型,併給齣瞭多狀態串併聯繫統平均性能的計算方法。構建瞭基于繫統性能與狀態分析的評估與維脩決策框架。以全懸掛轉爐傾動裝置二級減速機多狀態串併聯繫統的工作性能分析為例,對建立的分析模型的有效性和可行性進行瞭驗證。

The performance and state of the multi-state series-parallel connection system depend on the structure and the different state combinations of its components. In order to evaluate its reliability effectively, a quantitative analysis method about the work states and the performance of the multi-state series-parallel connection system was presented on this paper, based on multi-state system theory and probability theory. The equivalence sets of the multi-state series system, parallel system and series-parallel connection system under different states were established respectively. The computation models of the weighted average performance and state probability of each multi-state system under different states were presented based on the equivalence sets which could be divided by the performance level. The performance computation model of the multi-state series-parallel system was also presented based on the above analysis. The decision-making frame of system evaluation and maintenance was established based on the performance and states analysis of the system. An example about the work performance analysis of the two-level reducer multi-state series-parallel connection system of the full mounted converter tilting device was used to verify that the proposed method is valid and feasible.
