Abstract:A cell wheel metering device and the soybean seed were researched by using the discrete element method. The 3-D discrete element method analytical model of the seed metering device was built on its 3-D CAD model extracted through the method which was based on graphic elements and the surface mesh, and the 3-D particle model of soybean seeds were established on the spherical particle. The metering performance,the trajectories and dropping angles of the soybean seeds were simulated and analyzed by using self-developed 3-D CAE software. It showed that the metering performance,the dropping angles and trajectories of the seeds were good agree with the experiment results by comparing the analytical results of simulation. This result showed the feasibility of using the discrete element method to analyze the performance of the cell wheel metering device.

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.
