Parameter Calibration of Cabbages (Brassica oleracea L.) Based on the Discrete Element Method

The discrete element parameters of cabbages (Brassica oleracea L.) were calibrated for the design and parameter optimization a cabbage harvester. model was created based on study material characteristics simulation calibrated. intrinsic partial contact obtained by direct measurement. accumulation angle determined plate drawing test. Through steepest ascent test orthogonal rotation combination test, regression error established. optimal between minimum modeling. These applied in verification results indicated that simulated measured values only 1.63%, which demonstrated dependable. This can provide theoretical support designing optimizing harvesting machines with method (DEM).
