介绍了油菜少耕施肥条播机旋耕装置的结构和工作原理,在使用Pro/E软件设计该条播机的对行旋耕装置结构的基础上,选择一副旋耕圆盘为研究对象,分析了旋耕圆盘装置的运动学规律,并利用ANSYS Workbench软件对单幅旋耕圆盘的1/4结构进行了瞬态动力学分析,得出旋耕刀片在入土过程中,其变形和所受应力要经过3个周期性阶段变化,其中最大变形为1.297 mm,分布于旋耕刀片刃口,最大应力为272.5 MPa,集中在刀片与圆盘连接处。仿真与分析结果为油菜条播机的局部结构进一步优化和改进提供了必要的理论依据。
This paper introduces the structure and working principle of rape cultivating rotary tillage machine with less tillage fertilizer. Based on the structure of rotary tillage machine designed by Pro / E software, a rotary tillage disc is selected as the research object. The kinematics law of the rotating disk device was analyzed. The transient dynamic analysis of the 1/4 structure of the single rotating disk was carried out by ANSYS Workbench software. The results showed that during the soil cutting process, Stress undergoes three periodic stages of change, with the maximum deformation of 1.297 mm, distributed at the blade edge of the rotary blade, with a maximum stress of 272.5 MPa, which is concentrated at the connection between the blade and the disk. The simulation and analysis results provide the necessary theoretical basis for the further optimization and improvement of the local structure of rape seed drill.
