摘　　要：以某型液压挖掘机斗杆为研究对象,运用有限元分析软件ANSYS Workbench建立斗杆参数化模型,并对其结构进行静力学分析。基于DOE优化方法的斗杆优化设计,将参数化建模和多目标参数优化方法综合运用到斗杆结构设计中,通过灵敏度分析、局部优化分析确定最优设计方案。Taking a certain type of hydraulic excavator stick as the research object, the finite element analysis software ANSYS Workbench is used to establish a parameterized model of the stick, and its structure is analyzed statically. Based on the DOE optimization method, the optimal design of the stick is adopted. Parametric modeling and multi-objective parameter optimization methods are integrated into the design of the stick structure. The optimal design is determined through sensitivity analysis and local optimization analysis.
