Correlation analysis traction resistance of experimental section needle harrows

Abstract

Determined dependence horizontal and vertical components of the traction resistance of soil depth, speed and angle unit sharpening needles series (section сultivators УСМК-5.4) and experimental needle used harrows. Established that the resultant resistance force pilot needle harrows section, consisting of disks with different angles sharpening needles (50; 70; 90), to test all modes (speed 1.9 - 3.05 m/s, cutting depth 4 - 8 cm) was lower than analog. Noted stationary process, as evidenced by the fading correlation function with increasing time t.
