Methodology for numerical modeling of the sowing apparatus of a small-seeded crop selection seeder

Abstract

The article describes the methodology for numerical modeling of the process of sowing seed material of small-seeded crops in the STAR-CCM+ software package based on the created 3D model of the sowing machine and the accepted physical models. The boundary and initial conditions of the simulation are presented. To verify the created simulation of the developed sowing apparatus of the breeding seeder, a visualization of the process of its operation was obtained and the dynamics of quantitative seed consumption was determined. The average value of quantitative seed consumption and its standard deviation were calculated. It is substantiated that for further research, the following factors were chosen as research factors: the manufacture of a cylindrical metering device (I - triangle, II - semicircle, III - rectangle), the angle of rotation of the flap α, the time interval when the flap is open or closed Δt, the speed of movement of the seeder V.
