轻量化钵育秧盘的3D打印及有限元分析OA

During the research and development process of the new rice transplanter,the size of the rice transplanter needs to be continuously adjusted.In order to improve the research and development efficiency,3D printing technology is introduced to produce the rice seedling plate.In order to make the seedling tray closer to the actual working conditions,the seedling tray is hollowed to achieve lightweight.In order to ensure the strength of the seedling tray after assembly,only the No.3 block of the seedling tray is hollowed.Considering that the size of the seedling tray is larger than the maximum printing size of the 3D printer,the disassembly and assembly design of the seedling tray is carried out.In order to verify the rationality of the lightweight interlocking split seedling tray design,finite element analysis is conducted on three different design styles of seedling trays.The interlocking and split lightweight seedling trays is found to not only meet the lightweight requirements,but also have a small deformation range.Finally,a 3D printing trial is conducted on lightweight interlocking split seedling trays.Practical results show that the lightweight interlocking design of the seedling tray not only saves materials and is lightweight,but also meets the application mechanical performance requirements.
