Flax, an important oil and fiber crop, is widely cultivated in temperate sub-frigid regions worldwide. China one of the major producers flax, with Gansu Province predominantly practicing cultivation hilly areas. However, common issues such as feeding difficulties, stem entanglement, low threshing efficiency significantly restrict improvement planting efficiency. This study addresses key technical challenges flax combine harvesting by developing a discrete element model plant utilizing DEM-FEA co-simulation technology. The performance two drum models (T1 T2) was analyzed, focusing on motion trajectory, stress distribution, effects. simulation results show that T2 model, its combination rib rod tooth design, improves separation loss rate reduced from 5.6% T1 to 1.78% while maximum deformation were lower, indicating higher structural stability durability. Field validation revealed had total 3.32%, impurity 3.57%, 0.09 hm2/h. In contrast, achieved 2.29%, 3.39%, 0.22 hm2/h, representing 144.4% working These findings indicate has potential for mountainous regions, especially improving operational stability, providing theoretical basis optimizing equipment design.
