摘要：轻量化设计是航空航天、汽车、医疗等行业的重要需求,在降低能耗、提高性能等方面具有显著优势,增材制造技术通过逐层添加材料可以实现复杂结构的制造,点阵结构与增材制造技术相结合已成为高性能轻量化结构设计与制造的新思路。然而,增材制造点阵结构在服役过程中往往会受到循环载荷,发生疲劳破坏,结构轻量化与抗疲劳的协同仍是制约新一代航空航天等结构研发的难题。介绍了轻量化设计与制造方法,总结了点阵结构设计与制造技术,综述增材制造点阵结构疲劳性能研究进展,指出设计/制造一体化是增材制造点阵结构抗疲劳的可行路线。
Lightweight design is exceptionally needed in sectors including aerospace,automobile,and medical care because of its superiority in reducing energy consumption and enhancing performance of structures.Additive manufacturing can build complex structures by adding materials layer by layer.Today,the integration of lattice structure and additive manufacturing has shed new light on the design and manufacturing of high-performance lightweight structures.However,the lattice structure based on additive manufacturing is often subjected to cyclic loading in service and thus exposed to fatigue damage.The coordination between lightness and anti-fatigue property has yet been achieved in research and development of structures employed in the new generation of aerospace industry.In this review,an introduction of the methods utilized in design and manufacturing of lightweight structures is presented,and a summary of techniques in on the subject is given.After that,a review of the research on fatigue properties of additive-manufactured lattice structures is offered,and it is figured out that the integration of design and manufacturing is feasible to ensure the anti-fatigue property of these structures.
