摘　　要：首次将拓扑优化应用于吊臂的整体设计,从一个新的方向来研究吊臂的轻量化设计。首先选取类椭圆截面作为吊臂截面形式,在前处理器Patram中建立三节吊臂的有限元模型,设置好各项参数后提交Nastran尽兴有限元分析,得出各截臂应力。而后返回Patran,设置拓扑优化所需参数,提交Nastran进行计算,得出各截臂材料分布,结合实际情况,给出一种合理的材料分布方案,并重新建立模型求解,对比两次静力学分析结果,从而证明该拓扑优化是可行的。Topology optimization was the first time to be applied for the entirely design of crane boom. This was a new direction for crane boom light-weight design. Taking the Similar oval crane boom as the object, based on a pre-processor Patran, the finite element model was built. It set the needed parameters and submitted to Nastran to calculate. Then reseted the parameters for topology optimization and submitted the job to Nastran and went on with the topology optimization. Taking the optimization result with actual condition into consideration, a reasonable project was given. Rebuilt the model in Patran and did the statics analysis again. Comparing with the precious result, it approved that this topology optimization was successful.
