| 摘 要： | 采用ANSYS软件对免耕播种机缺口圆盘刀进行了有限元静强度分析。通过定义单元类型、材料属性，对圆盘刀进行了网格划分，从而生成了圆盘刀的有限元模型，载荷为切割作物秸秆的切割阻力以及切破地表、挤开土壤的切土阻力。通过求解圆盘刀的有限元模型，得到刀片的应力分布图，为缺口圆盘刀的设计和优化提供了理论依据。

Analysis for Gap Disc of No-till Planter |
| |
| Abstract: | In order to obtain better anti-blocking device on no-till planter, a finite element analysis on gap disc with ANSYS was conducted. Through element type selecting and material properties setting, ANSYS could transfer gap disc image into mesh size and generate a finite element model, in which loadings consisted of straw-cutting resistance and soil-penetrating resistance. Then the gap disc model was calculated, a series figure of different components of stress was obtained. Theoretical basis of further modification and optimization for gap disc was given. |
