论文摘要
我们提出了一种新型的杀菌方法，用于有效设计高分辨率承载结构。所提出的方法建立在设计域的基于流线的参数化基础上，使用一组从基于均质化的拓扑优化获得的两个相互正交方向字段中的一组空间填充且均匀的流线。这些字段中的流线被转换为图，然后将其用于构造一个四边形的网格，其边缘遵循方向字段。另外，根据优化的正性细胞的密度和各向异性，调整边缘宽度。在许多数字示例中，我们演示了所得结构设计的机械性能和定期外观，并将其与经典和现代方法的机械性能和相比。
We present a novel de-homogenization approach for efficient design of high-resolution load-bearing structures. The proposed approach builds upon a streamline-based parametrization of the design domain, using a set of space-filling and evenly-spaced streamlines in the two mutually orthogonal direction fields that are obtained from homogenization-based topology optimization. Streamlines in these fields are converted into a graph, which is then used to construct a quad-dominant mesh whose edges follow the direction fields. In addition, the edge width is adjusted according to the density and anisotropy of the optimized orthotropic cells. In a number of numerical examples, we demonstrate the mechanical performance and regular appearance of the resulting structural designs, and compare them with those from classic and contemporary approaches.
