中文摘要：

为优化花生收获机挖掘装置的性能和质量，提高工作效率，采用UG软件建立挖掘铲和立刀杆的实体模型并利用其高级仿真功能进行了有限元静力学分析。通过简化模拟挖掘装置的工作状态，对其进行受力分析，并根据挖掘装置的材料属性建立有限元模型，计算出不同条件下挖掘装置的变形和应力分布情况，对比得出最优设计参数。

英文摘要：

In order to optimize the performance and quality of the peanut harvester digging device, improve work efficiency In this paper, we analysis establish a solid model of mining shovels and vertical Arbor by UG software. In this pa- per, we use the advanced simulation capabilities of UG software to analyze mining shovel and vertical arbor solid model, which was established by UG. Simplify the mining equipment working state, and make sress analysis on it, Finite element model of the device according to the material properties of digging, calculate the deformation and stress distribution of mining equipment under different conditions, and the optimal design parameters by analyzing the results.
