随着油茶种植的规模化和产业化,实现油茶果机械化和自动化采摘成为急需解决的问题.针对上述现状,设计了油茶果采摘机.油茶果采摘机进行采摘作业时,其采摘执行机构中的关键零部件长期承受较大的周期性负荷.为确保采摘执行机构关键零件的安全性与可靠性,应对其进行力学验证.研究利用Inventor软件建立了采摘执行机构动力学仿真模型并进行了动力学仿真,得到了采摘执行机构的关键零件在振动采摘过程中的受力变化曲线.基于动力学仿真结果,建立了采摘执行机构关键零件有限元分析模型,开展了关键零件有限元分析工作.通过以上研究,发现采摘执行机构关键零件的最大应力均远小于零件材料的屈服极限,安全系数...

With the increase of camellia＇s cuhivated area, realizing the mechanized and roboticized camellia fruit harvesting has been the focus. Aimed at the status, we designed a type of camellia fruit picking robot. When the oil tea fruit-picking machine is working, the key parts of the pick actuators are subjected to a large cyclical load in the long run. In order to ensure the safety and reliability of key parts of the picking actuators, the mechanical validation of the key parts of the pick is to be carried out. This paper uses the software of the ...
