Theoretical study of the stability of asymmetric movement sowing machine-tractor aggregate

Goal. Theoretical evaluation of the effect asymmetric connection row drill to tractor on stability movement sowing unit in horizontal plane. Methods. studies were carried out using methods theoretical mechanics, higher mathematics and theory automatic control dynamic systems. Numerical calculations construction graphical dependencies performed a PC Mathcad 15.0 programming environment. Results. Practically all existing machine-tractor units for crops (corn, sunflower, soybean, etc.) are symmetrical. This is because each seeder has an even number sections, ratio size track width crop integer (k). article presents results research unit, which, with sections seeder, k equal 3, which odd. As result, was obtained, offset transverse direction from axis symmetry by half spacing, 70 cm. In practice, such displacement hanging it help specially designed transition device. Conclusions. With use mathematical modeling seeding plane, shown that right-side planter 0.35 m forms constantly acting turning moment. But less than similar moment created marker. Calculations have established increasing input resistance coefficients tires wheels, can be achieved correspondingly air pressure them, leads desired decrease amplitude-frequency characteristics unit’s development disturbance Such solution more effective concerning tractor’s rear wheels.
