Theory of movement of the combined seeding unit

(in lingua inglese)

Thus, we find all analytical expressions for the force factors that compose the system of differential equations, which describes the motion of a plane-parallel combined sowing unit consisting of aggregated tractor and hooked up behind him fertilizer distributing drills that band-pass method makes fertilizers and suspended on her grain drill. In this case, the obtained analytical dependence expressed in terms of generalized coordinates, and, consequently, the system of differential equations of motion after substituting the expressions obtained it will be closed, which gives every reason for its numerical solution on the computer.
