Kuvachov V. Increase of smoothness a course of machine-tractor units on the basis of modular power means class 1,4-3

Object is the process of functioning of the machine-tractor unit on the basis of modular power means (MPM) with its viscoelastic connection of power and technological modules, as components of uniform dynamic system. Purpose is to increase of technical, economic indicators of units on the basis of MPM by improvement of smoothness of their course. Methods. Modeling on the computer of conditions of functioning of the arable unit, use of positions of theoretical mechanics, statistical dynamics, frequency methods of the theory of automatic control of linear dynamic systems, probability theory and the correlation and spectral analysis. Novelty. For the first time the interrelation of design data of the back hinged mechanism of power module MPM with resistance factor in its hydrosystem is established; for the first time the mathematical model which allows to raise smoothness of course МТU on the basis of MPM by optimization of rigidity of its connection of power and technological modules is developed; new laws of influence of parameters of hydrosystem of the back hinged mechanism of power module MPM on characteristics of vertical fluctuations МТU are revealed. Results. Practical recommendations about increase of smoothness of course МТU on the basis of MPM which are introduced in the agricultural enterprises are developed, Open Societies "The Kharkov tractor factory of S.Ordzhonikidze" are accepted and Tavria State Agrotechnological University also use these practical recommendations are developed. Brunch is the farm production.
