Abstract: 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.
