Substantiation of parameters and operating modes of a cultivation and sowing unit as illustrated by a cultivation unit "KUZBASS-T"

The article considers the sequence of justifying calculations of rational parameters and operating modes of a machine-tractor aggregate using a mathematical probability model which describes the functioning process of MTA as a system “soil - agricultural machine - vehicle - transmission - engine” with an unsettled character of external influences. The basic data for the simulation are probability characteristics of draft resistance of the operating machine received by means of the method of test dynamometry in the course of field tests of the aggregate. The usage of the main theoretical issues of the probability model, which describes the functioning process of machine-tractor aggregate as a system “soil - agricultural machine - vehicle - transmission – engine”, for the substantiation of structures and operating modes of machine-tractor aggregates, based on the processing of experimental data, allows to estimate with a high degree of believability the outcome performance indicators of aggregates according to the set effectiveness criteria and to forecast their technical and economical results.
