Numerical Simulation and Verification of Seed-Filling Performance of Single-Bud Billet Sugarcane Seed-Metering Device Based on EDEM

The seed filling of a seed-metering device is critical process in sugarcane cultivation operations. To analyze the contact between billets, related mechanical components, and law billets movement device, simulation seed-filling based on EDEM was proposed, geometric model particle model, were established by software. physical experimental results angle repose compared. showed that relative error experiment 6.67%, which verified effectiveness material parameters single-bud billet; linear correlation coefficient 0.762 for Sq 0.869 Se, demonstrated validity using software to simulate process. Finally, velocity force particles analyzed EDEM. analysis indicated there are two circulation circles box, larger circle, easier enter rake bar. provides basis optimizing structure billet planter future work.
