ALGORITHM FORMATION AND ANALYSIS OF MOTION STABILITY OF THE MX-1.8 COTTON-PICKER AND THE HITCH SYSTEM OF HARVESTING UNITS UNDER VERTICAL VIBRATIONS

Abstract

The problem of studying the motion stability of the MX-1.8 cotton picker and the hitch system of harvesting units under vertical vibrations is considered and solved in the paper. The main objective of the study is to assess the stability of mechanical system; it is necessary to consider the stability of both the system as a whole and the stability of thehitch system relative to the tractor, this remains an urgent task that requires further study.In the formation of the motion stability algorithm, it is necessary to study the equations of motion of the MX-1.8 cotton picker and the hitch system of the harvester under vertical vibrations, when the hydraulic cylinder for raising and lowering the harvesting units is installed on the left edge of the rocking shaft; the rigidity of the rocking shaft is considered absolute, left and right harvesting unitsoscillate uniformly. The motion stability is checked by the Hurwitz criterion.
