摘要

摘要: 为分析出各单元在其他某些单元或分系统失效情况下的可靠度，并建立精确的可靠度模型。应用应力-强度分布干涉理论，并基于马尔可夫链和纯灭模型对行星传动中各重要零件单元的可靠度计算进行了分析，再建立行星轮系统的可靠度模型，推导了系统可靠度计算公式，得出风电机组变桨减速器的纯灭模型可靠度计算结果。实例计算分析表明：运用纯灭模型得到的可靠度，比传统方法更接近实际情况，并能从失效概率直观分析薄弱环节零件及其原因。

Abstract: To analyze the reliability of each part of the wind turbine pitch reducer under the case of other parts or subsystems failure and establish the accurate model for reliability, the reliability model of the planetary transmission system is established by using the theory of interference for stress-strength distribution, and base on Markov chain and pure death model, the formula of system reliability is deduced, and the reliability of the important parts of system is analyzed , and the result of the reliability of the wind turbine pitch reducer is then obtained. The example calculation and analysis results show that the reliability using pure death model is closer to the actual situation of parts and each system in actual situation. The proposed model is more objective than traditional model in reliability analysis. and it can intuitively analyze the weak links of parts and its causes from the view point of failure probability.
