摘要
针对单株块根作物收获机具短缺、结构设计粗放的特点,分析了辐盘式挖掘装置的结构及工作参数,并利用三维虚拟样机技术建立辐盘式挖掘装置的模型。同时,根据挖掘装置的受载情况,借助ANSYS软件,对挖掘装置的变形及应力进行有限元分析。根据分析结果,找出挖掘装置易产生损伤部位,为后续挖掘装置的优化设计及性能提升提供理论依据。
Aiming at the shortage of single-crop root-crop harvesting equipment and the extensive structure design,the structure and working parameters of the radial disk digging device are analyzed.The model of the radial disk excavating device is established by 3D virtual prototyping technology.According to the loading situation of excavating device,the paper analysis the deformation of the excavation device and stress by virtue of ANSYS software.According to the analysis results,it is easy to find the damage site of the excavating device,which provides a theoretical basis for the optimization design and performance improvement of the subsequent excavating device.
