元器件性能退化信息的系统性能可靠性评估

性能可靠性方法为解决现代工程实际中的高可靠、长寿命、小子样产品的可靠性建模分析提供了途径.目前的性能可靠性研究主要是针对元器件开展的,对系统性能可靠性进行研究时通常需要将其看作一个元器件,需要得到系统的性能退化数据,在某些情况下,得到系统的性能退化数据比较困难.实际上,由于元器件的性能退化导致系统性能的变化,因而可以利...

System Performance Reliability Assessment Based on Degradation Data from Components

Performance reliability methods provide an effective way for reliability modeling and analysis of highly reliable,long life,and small sampled products in modern engineering.The majority of existing performance reliability methods are developed for components.Systems are treated as a single component when using these methods.So usually system degradation data are needed,which are sometimes difficult to collect.As a matter of fact,the degradation of components results in the change of the system performance,s...
