摘　　要：针对山药收获机械自动化占比低、工作效率低、收获损伤率高并且需要人工辅助作业、污染环境等问题,结合山药生长环境和收获实际情况,通过对山药数据的分析、挖取方案的比较与选择,设计开发出一款可用于山药抓取、收集的机器。该机器主要由挖掘装置、去泥装置、打捆装置以及整体机架组成。使用SolidWorks软件对机器的各个零件进行建模,并利用有限元软件ANSYS对夹爪以及车架进行应力分析,发现在100 N的载荷作用下,夹爪最大应力为225.5 kPa,最大形变量为0.78 mm,车架最大应力为158.5 Pa,最大形变量为1.9669 mm,应力和形变均在允许范围。通过有限元分析结果,证实了结构的可行性。For the problems of low proportion of yam harvesting machinery,low efficiency,high rate of harvesting damage,manual assisted operation and environmental pollution,a machine that can be used for yam harvesting is designed and developed.The machine is mainly composed of excavation device,dredging device,baling device and overall frame.The machine is modeled by SolidWorks software and the stresses of the jaws and frame are analyzed by the finite element software ANSYS.It is found that the maximum stress of the jaws is 225.5 kPa and the maximum deformation is 0.78 mm under a load of 100 N,and the maximum stress of the frame is 158.5 Pa and the maximum deformation is 1.9669 mm.The stress and deformation are within the allowable range.After the results of finite element analysis,the feasibility of the structure is confirmed.
