摘　　要：航空航天等领域对轻量化高性能结构的需求日益迫切,突显了点阵结构在轻量化目标中的重要性及其广阔的应用前景。粉末床熔融技术的快速发展和成熟,使得复杂的点阵结构制备成为可能,并迅速成为研究热点。虽然当前关于增材制造点阵结构的研究已经比较丰富,但成果间的关联性和系统化整合仍然不足,有关点阵结构的最优设计和调控手段仍尚未形成系统的理论体系。因此,本文不仅介绍了点阵结构的基本特性和主要分类,系统探讨了增材制造点阵设计和制备对其力学性能的相关影响及其主要研究进展,还总结了点阵结构的未来研究方向和发展趋势。The increasingly urgent demand for lightweight and high-performance structures in aerospace and other fields has highlighted the importance of lattice structures in lightweight targets and its broad application prospects.With the rapid development and maturity of powder bed fusion technology,it is possible to prepare complex lattice structures,and it has quickly become a research hotspot.Although the current research on additive manufacturing lattice structures has been relatively rich,the correlation and systematic integration of the results are still insufficient.Moreover,there is a lack of consensus on the optimal design and control methods for these structures,and a comprehensive theoretical framework has yet to be established.Therefore,this paper introduced the basic characteristics and main classification of lattice structures,systematically discusses the effects of design and preparation of additive manufacturing lattice structures on their mechanical properties and major research progress,and also summarized the future research directions and development trends of lattice structures.
