摘要
对机械系统组成单元的含义作了新的定义,建立单元模糊可靠度及其置信区间的估计模型;建立了机械领域常见系统的模糊可靠度估计模型;通过对单元模糊可靠度的直接估计,利用所建立的估计模型可以快速方便地预测出系统的模糊可靠度。实例分析给出了估计模型的使用方法,并显示模型的有效性。
Defining new meanings for cell of mechanical systems. Estimating models are based for cell fuzzy reliability and its confidence interval. Fuzzy reliability estimating models are set up for mechanical systems. Fuzzy relianbility of sysytem cells is estimated firstly. System fuzzy reliability is calculated by system estimating models. Example analysis presents using method and shows validity of models..
