摘要：依据装载机的作业特点，对立式动臂在铲掘位置进行静力学有限元分析，计算出动臂的应力分布云图，并在有限元分析结果的基础上提出动臂结构的改进方案。优化后的仿真结果表明，在保证动臂满足工作性能要求的前提下，经优化设计后的动臂受力情况和结构形状得到了合理的改善。该基于ANSYS的有限元分析和优化设计方法提高了设计速度和设计质量，降低了生产成本。

Abstract：According to the working characteristics of loader, the static finite element analysis is performed in the shoveling and digging position for vertical movable arm, and the stress distribution is calculated. Base on the analysis result, the improved design is put forward. The simulation result after optimization shows that forces and structural shapes of the movable arm are improved after being optimized on the premise of meeting requirement of the movable arm’s work performance. The method of finite element analysis and optimization design based on ANSYS improves design speed and quality, reduces manufacturing costs.
Key words：loader；vertical movable arm；static；finite element analysis；optimization design
