| 摘 要： | 用变密度法建立了结构拓扑优化数学模型,阐述了利用有限元法进行结构拓扑优化的过程。以汽车上某支架为例,在有限元软件Hypermesh中进行拓扑优化设计,并对优化结构进行了台架试验。试验结果表明,结构拓扑优化结果与载荷大小无关;基于有限拓扑优化方法得到的结构优化方案是合理的受力承载结构。

| Abstract: | The structure topological optimization mathematical model is created with the variable-density method.The processes of structure topological optimization with FEM are introduced.As an example,a bracket of a car was optimized with HYPERMESH software,and bench tests of the optimized bracket were done.Test results indicate that structure topological optimization result is irrelevant with loads;the optimized structure with the FEM-based topological optimization method is rational. |
