Test and Simulation Analysis of Soybean Seed Throwing Process

In order to analyze the effect of different factors on bouncing and rolling distance soybeans at time seed throwing, tests discrete element method (DEM) are employed test soil three representative soybean varieties. The parameters between particles calibrated by means a piling simulation. A throwing apparatus is improved effects height, plane inclination angle collision orientation seeds. relative speed seeds analyzed using computer vision seeding bench. On this basis, above-mentioned procedure simulated compared with results. results showed that was not significant. had certain randomness when height different. When became larger, increased. sphericity high, orientations obvious. If low, shortest colliding in horizontal longest vertical orientation. larger speed, particles.
