Mathematical model of agricultural aggregate movement based on the Autotractor

Abstract

The paper presents theoretical studies of the movement of the agricultural unit on the basis of the MEZ-330 «Autotractor». An equivalent dynamic model of an agricultural unit on the basis of MEZ-330 «Autotractor» is presented. A system of differential equations has been compiled, which makes it possible to describe the interrelation of the main structural parameters of the unit and its operating modes. The results of modeling the motion of the MEZ-330 «Autotractor» on the implementation of technological operations are given. According to the simulation results, the dependences describing the influence of the mass of the MEZ-330 «Autotractor» on the coefficient of slipping of its wheels were established. It is established that the obtained theoretical dependences are adequate and correlate with experimental data with a 95% confidence probability.
