Based on the American NSWC-10 criterion, we analyzed the mechanical standard components failure mechanisms and failure modes, through which inducted their common methods and calculation models of reliability prediction according to their specific characteristics. Furthermore, they have been transformed into the metric system standards used in China. And also the development of the softwares interface, algorithm, connection and data preservation were accomplished utilizing C# development language in the integrated development environment of Visual Studio to realize the reliability prediction of mechanical standard components.
