Design for reliability highly responsible systems on the example of a moving rod

The article is devoted to one of the design technologies of highly responsible systems on the example of a rotating rod of a spacecraft. This technology allows take into account the specified requirements for reliability from the very first design solutions. An algorithm for constructing a generalized parametric model of the functioning of products is proposed, which is intended for carrying out the calculated and experimental verification of the output parameters of functioning and their correlation with the given reliability indicators. The methodology of the design & technological reliability analysis is presented, which allows performing analytical verification of the functioning parameters in order to identify necessary and sufficient requirements for performing computational and experimental verification and manufacturing products with a given reliability. This design technology, based on parameterization and design & technological reliability analysis, makes it possible to achieve reliability of mechanical devices whp R≡1, regardless of the type of mass production. At the same time, potential failures can be successfully eliminated or mitigated at the earliest stages of the life cycle (design and engineering), and the possible risks of the occurrence of failures are promptly evaluated.
