考虑异强度相关性下多元退化系统的可靠性置信评估OACSTPCD

For aero-engine operating systems with multiple performance degradation modes,a reliability confidence evaluation method based on random correlation is proposed considering individual differences and different strength correlations.The Wie-ner random process and Gamma random process with random effects were used to describe the performance degradation failure processes respectively.The Copula function of the randomization of relevant parameters was used to m…查看全部>>
