中文摘要:基于离散单元法,利用EDEM软件对水平转筒内大豆颗粒运动的随机性与混合特性进行了模拟研究,分析了转筒转速与装载量对颗粒随机运动及混合特性的影响。结果表明:转筒转速的提高有利于改善颗粒的随机运动过程,而且颗粒的混合效果增强,混合速度加快。装载量的影响相反,随着装载量的增大,颗粒在转筒径向方向的随机运动虽有增大,但堆积现象比较明显,沿转筒轴向方向的随机运动明显降低,颗粒的混合速度变慢,混合效果变差。

Abstract:Simulation study on random motion and mixing characteristic of soybean in a horizontal rotary drum was carried out based on discrete element method with EDEM. The effect of the rotation speed and load of the drum on particle random motion and mixing index was analyzed. It was found that the increasing of the rotation speed improved the random motion of particle, enhanced the mixing effect of particles, and speeded up the mixing process. Soybean load had the opposite effect. With the increasing of load, although the particle random motion was increased in the radial direction of the drum, the phenomenon of accumulation was more obvious and the random motion was significantly lower along the rotary drum axis direction. The mixing rate of particles was slow and the mixing effect became poor. 

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
