Simulation Analysis on Key Mechanisms of the Automatic Tobacco Harvester Based on ADAMS

摘要

Tobacco is widely cultivated in many countries. However, manual harvesting of tobacco leaves cannot meet the requirements of modern agriculture. Therefore, it is essential to develop the mechanized tobacco harvester. In this paper, an automatic tobacco harvester was designed and analyzed. The virtual prototype model was established using ADAMS. The traveling performance of the automatic tobacco harvester was analyzed using ADAMS/Tire. It can be found that the harvester work well on a flat sandy loam soil road. In addition, kinematic and dynamic simulation analysis on lifting mechanisms of the automatic tobacco harvester based on ADAMS were carried out. The results showed that the kinematic trajectory can meet the design requirements. Meanwhile, the dynamic parameters of key mechanisms were obtained, which would provide basic parameters for the design of the subsequent hydraulic system.
