基于动态拓扑信息模型的结构概念设计方法

摘要

In order to explore conceptual design method of the structure, which is feasible and practical in the engineering, the conceptual design method and the dynamic topology information theory are integrated. A micro-material interpolation model and a macro structure model dealing with the topological information of the structure are proposed. And then, using the technology of search node, border smoothing and the artificial intervention in regions of interest extracts topology map, and the structural design of the initial layout is gotten. Results of example illustrate its robustness and effectiveness. It can meet the needs of the concept design in the engineering projects.%结构初始概念设计对于最终零件的性能有决定性的影响.文中通过建立微观结构模型、应用宏观结构离散单元属性迭代更改的方法,将宏观和微观模型两者进行映射,实现微观结构设计与宏观设计一体化整合.然后利用节点搜索、边界光顺和感兴趣区域人工干预的融合技术提取拓扑图,并建立了结构设计的初始布局,通过建立动态拓扑信息模型完成结构的概念设计.最后用示例验证了方法的可行性,从结果可以看出,基于动态拓扑信息模型进行的结构概念设计的方法,能够满足工程结构初始概念设计的需要.
