摘　　要：复合材料点阵结构以其优异的力学性能越来越受到人们的广泛关注,文中在点阵结构的基础上,提出了直柱型点阵结构填充聚氨酯材料的新型复合夹层板结构,利用有限元软件ANSYS研究其静态力学性能.分别研究了夹心层高度、面板厚度等变化对其刚度性能的影响,并将该结构与实体板、普通聚氨酯夹层板进行对比,得出对工程实际具有一定参考价值的结论.The composites lattice structure gets more and more attention for its excellent mechanical properties. This article proposes a new type of sandwich plate -Straight lattice structure filled with polyurethane material based on previous studies, and uses the finite element software ANSYS to study the static mechanical properties. Stiffness properties are studied in tearms of the height, panel thickness and other aspects of the sandwich, and the structure was compared with physical hoards, and ordinary polyurethane sandwich Danels.
