中文摘要:根据运动学原理,建立了螺旋叶片板齿组合式轴流装置中稻谷的运动模型。通过计算机仿真得到了谷物运动的切向速度、轴向速度、绝对速度随时间的变化规律。谷物运动中的切向速度大于轴向速度,切向速度是构成绝对速度的主导因素,并利用高速摄像进行了验证,验证结果表明理论仿真结果与试验相一致。

Abstract:According to the fundamental of kinematic, a motion model of rice in the assembled plank-tooth and helical vanes axial flow threshing and separating device was established. Through computer simulating, the variable rule of grain tangential velocity, axial velocity, absolute velocity and time has been obtained. The results indicated that grain tangential velocity is greater than axial velocity, tangential velocity is the chief ingredient in the making of absolute velocity, through high-speed photography validating, the result indicated that the test according to those motion models agreed to the theory, and the analytic result laid a solid foundation for the development of the 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.
