Abstract

The purpose. To increase efficiency of operation of fertilizing- and-sowing aggregate in surging plane by justification of its scheme and design parameters. Methods. Basic positions of theoretical mechanics, statistical dynamics, the theory of autocontrol of linear dynamic systems and theory of a tractor, creation of programs for calculation on the PC. Results. New mathematical models of operation of the combined fertilizing-and-sowing machine-tractor aggregate in surging plane are developed. Their application allows justifying constructive and kinematic parameters of the aggregate. Conclusions. For security of the best controllability of driving the combined fertilizing-and-sowing aggregate the preference should be given to great values of distance from points of the trailer of fertilizer sower and grain drill to the centers of their masses and length of short tongue of fertilizer sower and grain drill. Thus boundary of increase of length of short tongue of fertilizer sower is such which predetermines trouble-free maneuverability of the combined aggregate.
