介绍了BYJ-800型油茶嫁接机的基本结构和工作原理，着重分析了穗木苗的力学特性，并以此作为穗木切削机构设计的参考因素。应用Ansys Workbench软件对切刀进行有限元分析和寿命仿真，得到切刀产生应力集中和容易发生结构失效的位置。通过对比普通亚共析钢和Cr12MoV模具钢两种材料的等效应力云图和寿命曲线得出Cr12MoV模具钢具有更高的淬硬性和机械强度，更适合做油茶嫁接机穗木切刀的结论。
介紹瞭BYJ-800型油茶嫁接機的基本結構和工作原理，著重分析瞭穗木苗的力學特性，併以此作為穗木切削機構設計的參攷因素。應用Ansys Workbench軟件對切刀進行有限元分析和壽命倣真，得到切刀產生應力集中和容易髮生結構失效的位置。通過對比普通亞共析鋼和Cr12MoV模具鋼兩種材料的等效應力雲圖和壽命麯線得齣Cr12MoV模具鋼具有更高的淬硬性和機械彊度，更適閤做油茶嫁接機穗木切刀的結論。

The basic structure and working principle of the BYJ-800 camellia grafting machine are introduced, the mechanical properties of the seedlings caspica is analyzed ,as the reference for the design of caspica cutting mechanism. The finite element analysis and the cutter life simulation with the software of Ansys Workbench are completed, the stress concentration of the cutter and the location of the structural failure is analyzed. Contrasting the equivalent stress and the life curve between the sub-eutectoid steel and the mold steel, Cr12MoV tool steel has a higher mechanical strength, which is more suitable cutter for the camellia grafting machine.
