手持式桉树幼苗种植器是一种简易的苗木种植辅助工具，在林地面积较小、林地为山地时，由于常常不适宜使用大型机械化作业，此时有广泛实用价值。本研究针对自行设计的手持式桉树幼苗种植器动杆部分使用SolidWorks软件进行三维实体建模并导入Ansys-Workbench软件开展有限元静力学分析，在此基础上进行疲劳分析，找出其薄弱区域和寿命曲线，通过分析得出最大破坏应力为3.6772×108Pa,最小安全因子仅为0.26047,100%载荷条件下循环寿命约为5000次，各指标的限制因素均出现在焊接部位。

The hand-held seedling planting device is a simple auxiliary tool which can be used in seedling transplantation;it will be widely used during to the unavailable mechanical operation under the small forest area and mountainous region. In this study, the rod part of the hand-held seedling planting device would be modeled through the SoldiWorks software and the Finite static analysis could be conducted with introducing the Ansys-Workbench software. Based on these works, the fatigue analysis can be conducted, the weak areas can be found and the life curve can be drew. According to the analysis, the maximum fail stress is 3.677 2 × 108Pa,the minimum safety factor is 0.260 47,the cycle life was about 5 000 times under full load. The limit factor is the welding position.
