Abstract
A possible approach to assessment of factors influencing the service-life parameters of electrical equipment on locomotives and the variants of their states is considered. The scheme proposed for the variants of states can be carried out as a system of rolling-stock maintenance. The need to increase the reliability of electronic and electrical equipment is especially acute during the operation of high-speed rolling stock, given that circuitry and structural solutions are extremely complex. In developing the computational systems and their capacity, it becomes possible to calculate large data volumes and update the problem of constructing optimal variants of state development in complex technical systems. The costs for rolling-stock maintenance and repair can be reduced by using both maintenance-free elements of rolling stock and an assembly or a part of rolling stock with a complicated structure. In connection with this, new assemblies consist of several elements with known indices of reliability and service life, but have different characteristics as a whole. An approach to technical indices of assemblies and elements as static values of certain functions is considered. A decomposition approach to an integrated reliability index and variants of planning the extents of repair and maintenance that need to be undertaken is carried out depending on the variants of states of an electromechanical assembly in rolling stock.
