Abstract

In the design process of corn combine harvester, there is a high demand for customization and diversification in China. Aiming at the problems of backward design method, lack of design knowledge and long product development cycle, the discrete beam method is used to establish the corn plant model. 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.

我国玉米联合收获机在设计过程中，存在定制化、多样化需求高的特点，针对其设计方法理论落后、设计知识匮乏，产品开发周期长等问题，采用离散梁法建立了玉米植株模型，利用 UG 建立了分装置器和纵卧辊式摘穗装置模型，运用 ADAMS 软件建立了其虚拟样机模型，进行了分禾装置与玉米植株以及摘穗辊运动学和动力学性能仿真试验。通过该方法实现了分禾装置和摘穗辊参数设计的系列化，提供了评价分禾性能和摘穗性能的方法，缩短了开发和设计周期，为玉米收获机割台的研发和设计提供了一定的参考和理论依据。
