SIMULATION ANALYSIS ON THE PERFORMANCE OF SPLITTING AND PICKING DEVICES OF CORNHARVESTER

摘要

In the design process of corn combine harvester in China, there is a high demand for customization and diversification.Aiming at the problems of backward design method, lack of design knowledge and long product development cycle,the performance simulation of corn harvester's divider and snapping roll for hilly area was analyzed by using ADAMS. The model of sub-device and the vertical and horizontal roller picking device is established by using UG,and the virtual prototype model is established by using ADAMS software. Meanwhile, the simulation experiments on the kinematics and dynamics performance of the separating device, the corn plant and the picking roller are carried out. Through this method, the design parameters of the separating device and the picking roller are serialized, the method of evaluating the separating performance and the picking performance is provided, and the development and design cycle is shortened, which provides certain reference and theoretical basis for the development and design of the corn harvester header.
