摘 要: 建立了籽粒自由运动微分方程式 ,对籽粒与外壳的碰撞过程进行了动力学分析 ,从理论上建立起结构参数和运动参数与籽粒运动轨迹之间的联系。 The differential equations of free grain motion in air flow were developed. The dynamics of the grain impact against the hood and conduit was analysed. As a result, the relationship between structural operating parameters and grain trajectories was theoretically determined.
