Establishment and Calibration of Discrete Element Model for Coated Wheat Seed Based on Static and Dynamic Verification Test
Year: 2024
Type: article
Abstract: This study calibrated discrete element parameters for coated wheat seeds through static and dynamic validation tests. Using physical experiments, key parameters were measured, and a discrete element model was created. Optimal parameters were identified via the Plackett-Burman test, steepest ascent experiment, and Box-Behnken design. Validation tests showed that the relative error between the simulated and actual angle of repose was 1.31%, and the relative error in seeding uniformity and seed displacement uniformity was less than 5%. These findings provide theoretical support for optimizing seed dispenser structures in precision wheat sowing.
