| 摘 要： | 玉米柔性体模型的建立是研究玉米植株与玉米收获机构刚柔耦合多体动力学系统的关键步骤.根据玉米植株参数,通过有限元软件ANSYS建立了茎秆模型,对模型进行网格划分和接触点定义,生成ADAMS需要的模态中性文件.将建立的收获机构模型和模态中性文件导入ADAMS后,施加载荷、约束和驱动,对茎秆的运动状态进行了模拟,得出茎秆位置、速度等试验数据,研究茎秆在机构间的运动状态,为后续分析提供依据.

| Abstract: | The establishment of flexible corn model is a key process of the corn-harvest mechanism, which is a kind of rigid-flexible coupling multi-body system. A modal neutral file for ADAMS was created in ANSYS by meshing the stem model and defining the attach point. The model of harvest mechanism and the modal neutral file of corn stem were imported into ADAMS. The status of motion of stem was simulated by applying load, constraints, and drive. And from the simulation, the variation of location and velocity were obtained. The status of motion in the mechanism was studied. |
