摘　　要：以小区小麦联合收获机的旋风分离清选系统为研究对象,运用Gambit软件对其核心部件-旋风分离筒前处理,运用Fluent软件对其内部流场进行了数值模拟。采用DPM模型模拟了小麦颗粒、茎秆和颖壳在分离筒中的运动情况,以颖壳分离效率、茎秆分离效率和小麦籽粒损失率为评价指标,对三种模型进行了对比分析,获得最优模型并进行了实验验证。Studying on cyclone separation cleaning system of the wheat combine harvester in this paper,its core component--cyclone separation cylinder is computed by using the Gambit software,numerical modeling of the internal flow field is completed by using the Fluent software. The movement of wheat grain,stems and shells in the separation barrel is simulated by using DPM model,and after comparative analysis of these three models in the aspects of the separation efficiency,stalk separation efficiency and wheat grain loss rate,the optimal model is obtained and then tested by experimental verification.
