The integration of topology optimization with lattice structures has shown great potential for the additive manufacturing (AM) of lightweight structures with superior mechanical properties and multifunctional characteristics. To further improve the design manufacturability, structural efficiency, structural isotropy and computational efficiency, the homogenization-based topology optimization (HMTO) method was proposed to integrate with plate–lattices exhibiting superior mechanical properties and excellent elastic isotropy. The validity of the proposed method was demonstrated by comparing the optimized models with conventional models composed of truss–lattices and solid materials. Results show that the proposed method highly improves stiffness and energy absorption capability.

拓扑优化与晶格结构的集成已显示出具有优异机械性能和多功能特性的轻质结构的增材制造（AM）的巨大潜力。为了进一步提高设计可制造性、结构效率、结构各向同性和计算效率，提出了基于均质化的拓扑优化 (HMTO) 方法来集成具有优异机械性能和优异弹性各向同性的板-晶格。通过将优化模型与由桁架-格子和固体材料组成的传统模型进行比较，证明了所提出方法的有效性。结果表明，所提出的方法极大地提高了刚度和能量吸收能力。
