【摘要】 通过建立种子充入型孔过程中的运动微分方程,对充种过程进行计算机模拟,说明了模拟方法思路,绘出了流程图。分析了排种轮直径、充种初始角、种子初始角速度等对充种极限速度的影响;导出了纯重力充种的充种极限速度解析式;对排种器充种机理进行了探讨。更多还原

【Abstract】 This paper establishes the differential equations of motion for a seed in feeding process, simulated by computer, explains the simulating idea, shows the program flow chart. Thereby analyzes the influence of seedplate diameter, initial angle and angular Telocity of a filled seed on limiting filling speed. Under seeds filled by gravity, analytic equation of limiting velocity is conducted. The mechanism on filling seed is approached.更多还原
