Abstract: Aiming at the elevator equipment of potato harvester, an integration simulation method based on Adams-Matlab and limit algorithms used in anti-collision control was proposed. The simulation and pre-description on the anti-collisions of two-freedom elevator were carried out by analyzing the anti-collision problem. The curves of angle θ1 and θ2 of potato harvester elevator with the time, the curves of distance between the end of harvester elevator and potato pile with the time, and the curves of distance between the elevator and the trailer with the time, were obtained respectively. The results showed that the limit algorithm and control method for this case was feasible, and the anti-collision of elevator motion was satisfying.

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.
