利用拓扑优化法解决设计优化问题

摘要

文中结合有限元方法中的拓扑优化，在零件结构特性分析的基础上，考虑装配约束，对零部件进行优化设计。首先利用 SolidWorks 对零件进行三维建模，然后利用 HyperMesh、ABAQUS、Optistruct 等软件完成拓扑优化后得到最终结果，即为最优解。经过优化各部分结构更加趋于合理。分析结果表明，约束和载荷条件相同的情况下，改进其结构尺寸，可以有效地调高零件强度、刚度，与此同时，大大减轻了零件的重量，提高其使用能力，最终得到符合实际装配需要的设计。%In this paper,to optimize the design of parts according to the topology optimization of the finite element method,based on analysis of characteristics of the structural components,considering the assembly constraints.The first use SolidWorks for three-dimensional modeling of parts,and then complete the topology optimization to get the final result by HyperMesh,ABAQUS,Optistruct and other software,which is the optimal solution.The various parts of the struc-ture will be more reasonable,analysis results show that,under the same conditions of load and constraint,improve its structure and size,can effectively increase the strength,stiffness,at the same time,greatly reducing the weight of parts, improve its service ability finally can meet the design needs of the actual assembly.
