CONTRIBUTIONS TO THE STUDY OF STABILITY IN THE TRANSVERSAL PLANE OF THE SYSTEM TRACTOR - TOWED FORAGE HARVESTER MACHINE

Abstract

The towed machines for mowing and crushing forage plants, also called forage vindrovers, performing cutting, crushing, collection and leaving plants in furrow on the stubble have got a large spreading. The towed vindrovers are disposed eccentrically, usually placed unbalanced in the lateral right side of tractors. The dynamics of systems tractor-working machine towed in unbalanced position to the longitudinal axis of the tractor has a certain particularity against the systems with symmetrically coupled to the tractor machines. The paper is an analysis of external forces acting in the transverse plane on the aggregate tractor - towed forage harvester combine at movement in working on horizontal land. From the equations of equilibrium of forces is determined equilibrium conditions and stability at sliding of the tractor in the transversal plane under the action of the machine eccentrically coupled to the tractor and elaborate the mathematical models that allow simulation of system behavior under different conditions of working and moving.
