RESOURCE-SAVING MAINTENANCE AND REPAIR OF SPECIAL SELF-PROPELLED ROLLING STOCK

The article provides the issues of improving the models of reliability and optimization of maintenance and repair of special self-propelled rolling stock (SPRS) with a compatible system of diagnostics. A new maintenance strategy is proposed, taking into account the new requirements of the self-propelled rolling stock. Examples of solving practical problems of reliability indices are considered.
 The study of the reliability of SPRS, as an object, is advisable to start with its presentation in the form of a system of assembly units. In this sense, the level of consideration is important. Figure 1 gives a structural diagram of SPRS, as a system consisting of elements. for several possible levels of consideration. SPRS, as a system of elements, makes it possible to concretize the task of analyzing and improving the reliability model and developing measures to perfect it.
