Hrynkiv A. Methods of diagnosing and forecasting of the technical condition of power units of transport machines by using of time series

In this dissertation the technological problem of increasing the reliability of systems and components of means of transport by the formation of a maintenance strategy and the control of their technical condition on the basis of forecasting is solved. Theoretically the function of a technical condition of means of transport is proved. The physical-information approach to the formation of the optimal information about it on the criterion of statistical informative value of diagnostic parameters is proposed. The relationship between the parameters of the technical condition and reliability using the criterion of relative sensitivity is established. Theoretically predicted and experimentally determined mileage intervals which are controlled and regulated in order to improve reliability. The methodological support for finding of the main units, which are limiting of resource, of informative important parameters and procedures for forecasting changes in their technical condition are developed. Experimental studies of the regularities of changes of technical condition and diagnostic parameters and reliability of systems and components of means of transport in the conditions of agricultural production have established. The technical and economic efficiency of the adapted system of technical operation of means of transport are defined. Recommendations to the services operations are developed.
