摘要
金属点阵结构具有轻质、高比强度、高能量吸收等特点,在航空航天、生物医学等领域有着广阔的应用前景。快速发展的激光粉末床熔融技术可精确调控点阵结构参数,进而实现金属点阵结构的材料-结构-性能一体化设计与制造。因此,本文以杆状点阵结构、板状点阵结构及三周期极小曲面点阵结构等常见的点阵结构类型为顺序,综述了激光粉末床熔融金属点阵结构的力学响应机制、破坏失效行为、结构优化设计及激光粉末床熔融技术对金属点阵结构成型质量、力学性能的影响,进而从结构设计及优化、激光粉末床熔融技术、功能性设计等角度,提出激光粉末床熔融金属点阵结构可能面临的机遇和挑战。
Because of its light weight,high specific strength and high energy absorption capacity,the metal lattice structure has great application pros-pects in aerospace,biomedicine and other fields.The laser powder bed fusion technology accurately controls the structural parameters of lattice structures,and then realizing the material-structure-performance integrated design and manufacturing of metal lattice structures.Therefore,in this paper,the mechanical response mechanism,failure behavior,structural optimization design and the influence of laser powder bed fusion on the forming quality and mechanical properties of metal lattice structures are reviewed in terms of common lattice structure types such as rod-shaped lattice structure,plate-shaped lattice structure and three-period minimal surface lattice structure.Furthermore,from the perspective of structural design and optimization,laser powder bed fusion technology,and functional design,the opportunities and challenges that metal lattice structures may face are proposed.
