摘　　要：以某液压挖掘机动臂为研究对象,运用有限元分析软件ANSYS Workbench建立动臂参数化模型,并对其结构进行静力学分析。选取动臂参数化模型中主要设计参数作为结构轻量化设计的优化变量,利用优化软件OptiSLang对结构进行优化设计。以动臂总质量最小为优化目标,在保证结构具有足够刚度和强度的条件下,寻求最优设计方案,使动臂结构具有最佳承载形式,并通过对优化后的动臂结构进行刚度及强度校核,验证该优化方案的可行性。Weight-reducing design of excavator's boom.We placed a hydraulic excavator's boom as an object for discussion by utilizing finite elements analysis software ANSYS Workbench to have constructed a parametric model for the boom which structure was statistically analyzed.Besides,we selected major design parameters from the boom's model as optimal variation in the design before utilizing optimal software OptiSLang the structural design optimization.And then,we set minimal mass of the boom as our optimal target to seek an optimal design concept on conditions that sufficient rigidity and strength of the boom structure can be ensured,so that the structure can get a best load bearing manner before checks on the structural rigidity and strength after the optimization,thus proving feasibility of the optimal concept.
