基于EDEM的碾白室结构优化仿真与试验OA

To reduce the breakage rate of rice during processing in horizontal rice mills,this study es-tablishes a double-layer bonded particle model based on discrete element method(DEM)numerical simulation.A three-factor,nine-level orthogonal experiment was designed.Range analysis identifies the height of milling tendons as the most influential factor on breakage.The optimal structural parameters were determined as follows:a resistance piece height of 5 mm,a milling tendon inclination angle of 4°,and two milling tendons.This parameter combination effectively mitigates the breakage rate,pro-viding a theoretical basis for structural optimization of the milling chamber in horizontal rice mills.
