DEVELOPMENT OF THE ESTIMATING METHODOLOGY OF A 5TDF ENGINE MOTOR RESOURCE CONSUMPTION UNDER DIFFERENT OPERATING MODES OF THE MACHINE

Abstract

The subject matter of the article is accounting for the motor resource of the 5TDF tank engine under different operating modes.  The goal of the study is to development of a methodology for estimating the consumption of a motor resource of a 5TDF engine under different operating modes of the machine. The tasks to be solved are: based on the analysis of data on the operating modes of the 5TDF engine, to determine a set of parameters that give empirical and analytical estimates of the consumption of the motor resource of the machine; to request analytical estimates of the consumption of the 5TDF engine motor resource in terms of the number of years’ service in different machine operating modes; to propose a mechanism for the processing of numerical values, depending on the results of the statistical processing of these machine operation data. General scientific and special methods of scientific knowledge are used. The following results were obtained: A continuous functional dependence of the actual number of hours spent by the engine on the values of the meter per hours at different speeds, allow more careful accounting of engine consumption, but will involve the development of special devices based on modern elements has been determined. Conclusions. It is possible to make a conclusion about the nonlinear nature of the dependence of the engine life on time with different engine operation at different load modes. Engine operating modes, which are determined by load resistance, are characterized by the number of revolutions of the engine crankshaft and the amount of power developed by the engine, largely determine its energy and economic performance of the engine and engine consumption. The testing ground for the consumption of the motor resource of the machine, depending on the readings of the engine hours counter, can be formed on the basis of the data obtained from the results of the operation of the machine in different conditions. The analysis of the results of the research carried out that finding dependence of a 5tdf engine motor resource can be presented as the sum of two regressions ‒ linear and hyperbolic. The readings of the engine hours counter will be recorded and further processed when the 5TDF engine is running in I-V and VI, VII gears, respectively. Such realization will make it possible to use the regression equation directly for the car crew.
