摘要:通过拓扑优化寻找机身材料的合理布置,以闭式压力机组合机身为研究对象,利用SolidWorks建立机身的三维模型,然后导人到HyperMesh中,建立有限元分析模型。采用变密度法,以静力学分析为基础,定义材料的密度为设计变量,设置不同的约束条件和目标函数,通过OptiStruct求解器对机身进行拓扑优化。通过对比两种方案的优化结果,改进机身的结构,并对优化后的模型进行静力学和模态分析,验证了优化后的压力机机身符合实际使用要求。优化后压力机机身重量减少 7.6%,实现了机身的轻量化,节约了成本,提高了企业的竞争力。

Abstract: A reasonable layout of the fuselage material was found by the topology optimization. Then, for the combined frame of straight side press , its threedimensional model was established by SolidWorks , and the finite element analysis model was built by HyperMesh. Based on the variable density method and the static analysis, the density of material was defined as the design variable, the topology opti-mization of fuselage was carried out by OptiStruct solver under different setting constraints and objective functions, Comparing with the op-timization results of two schemes, the structure of fuselage was improved, and the optimized model was analyzed by static and modal analy-sis. Finally, it is verified that the optimized press boly meets the requirements of actual use. The weight of press frame decreases by
7. 6% to achieve the lightweight boxly, save eosts and improve the competitiveness of enterprises after optimizing Key words : press; combined frame; OptiStruct; variable density method; topology optimization
