| 摘 要： | 考虑到退化失效型产品性能下降主要表现为状态参数发生漂移,可靠性评估模型中随机参数具有模糊特性,提出一种利用状态信息评估模糊可靠性的方法.采用随机冲击累积失效模型描述退化过程,模糊化参数漂移的动态范围,引入模糊隶属函数,推导出产品模糊可靠度的分析模型.结合具体实例进行验证,对比分析了不同隶属函数下的模糊可靠性与常规可靠性...

| Abstract: | Considering that the main feature of the decline of the degradation failure product's performance is the drift of state parameter,and the fuzzy uncertainties of the parameters of stochastic variables,a fuzzy reliability analysis method based on product state information was put forward.The random cumulate impact failure model was used to describe the degradation process and fuzzify the dynamic ranges of the parameter's drift.The fuzzy reliability analysis model was deduced by using fuzzy membership function... |
