The control experiments using a grain sensor have conducted. The investigations were attempted by means of experimentation and theoretical examination, the aerodynamics of grain acted upon by the winnowing wind. Estimation the trajectory of a single grain and grains layer by conducting experiments and solving equations for dynamic balance was attempted. Moreover, the particle image velocimetry and the finite volume method were used to attempt visualization of the cleaning wind flow in order to improve the effectiveness of the winnowing wind.Simulating the trajectory of a grain of paddy in the winnowing chamber was aimed. The drag and lift coefficients of a grain of paddy were calculated and changing these coefficients due to changes in the direction of the grain were examined. As a result, the drag and lift coefficients can be expressed as a trigonometric function of the direction of the grain.The simulations of a grain and the layer in a wind tunnel with a known and stable wind velocity were attempted in order to clarify the trajectory. Dynamic equations for grains of paddy were formulated by considering all forces affecting the grain blown by the wind. It was found that it was possible to simulate the trajectory of a grain.Array of vectors for the wind flow in the winnowing chamber was investigated in order to improve the winnowing accuracy. The vectors generated by means of the FVM and PIV method. It was found that the results of the analysis using FVM and PIV coincide with results obtained by the anemometer, The wind maps obtained by these methods are expected to provide essential data for understanding the characteristics of the trajectories of grain and chaff These results demonstrate that the performance of the cleaning section can be estimated from the initial design.

使用晶粒传感器进行了控制实验。尝试通过实验和理论检查尝试了调查，晶粒的空气动力学作用于奖励风。试图通过进行实验和求解动态平衡的方程来估计单个晶粒和晶粒层的轨迹。此外，使用粒子图像速度法和有限体积方法来尝试可视化清洁风流，以提高赢家风的有效性。瞄准了在奖励室中粒料的轨迹的轨迹。计算了谷物晶粒的阻力和升力系数，并由于晶粒方向的变化而改变了这些系数。结果，拖放系数可以表示为晶粒方向的三角学函数。晶粒的模拟和风隧道中的模拟试图以已知稳定的风速速度来阐明轨迹。通过考虑影响风吹动的所有力来制定稻谷晶粒的动态方程。发现有可能模拟晶粒的轨迹。研究了获奖室中风流的矢量阵列，以提高奖励精度。通过FVM和PIV方法生成的向量。发现使用FVM和PIV与通过风速计获得的结果相吻合的分析结果，这些方法获得的风图有望提供必不可少的数据，以了解谷物和谷物的轨迹的特征，这些结果表明，清洁部分的性能可以从初始设计中估算出来。
