基于Copula的机械系统可靠性模型及其应用

摘要

There is a complex correlation in the reliability of mechanical system. A reliability model of Copula-based mechanical system is presented by taking the advantage of Copula in describing correlation. The application of the model in mechanical system reliability prediction is described by taking a suspension system of some type armored vehicle for example. The result shows that the model can be perfectly used in the reliability prediction of mechanical system.%机械系统可靠性中存在复杂的相关性,利用连接函数Copula在描述相关性方面的优势,提出了基于Copula的机械系统可靠性模型.以某型装甲车辆悬挂系统为例,阐述了其在系统可靠性预计中的应用.结果表明,该模型可以较好地解决机械系统的可靠性预计问题.
