A COMPLEX APPROACH IN ASSESSING RELIABILITY INDICATORS OF ELEMENTS OF TECHNICAL SYSTEMS WHEN DEGRADATION FAILURES OCCUR

The construction and practical use of complexes mechanical reliability models creates real prerequisites for the transition to resource design assembly units aggregates mobile machines. Therefore, article solves tasks building inverted stochastic models, which provide possibility joint statistical analysis heterogeneous information about in cases types destruction typical machine elements: during wear fatigue. A fairly complete convenient method solving many problems is given describing a non-stationary monotonic degradation process, consists task type its function or density distribution time segments with parameters that are deterministic functions working load cycles. Such should be perceived as parametric. Schemes two main processes elements also given: monotonically increasing, associated decreasing, due fatigue failure. At same time, process corresponding formed by random realizations change failure parameter over characterizing set individual curves depend on cyclic durability. considered theoretical determine made it possible develop universal approach provides evaluation model caused tear destruction. proposed expedient both accelerated assessment predicting at stage
