摘要

为获得高承载效率的复合材料空间点阵结构，利用有限元法对复合材料圆柱空间点阵结构的稳定性进行了分析。结合 ANSYS 的二次开发语言 APDL编写了圆柱空间点阵结构参数化设计程序，并运用该程序研究了空间点阵结构载荷质量比随内蒙皮厚度、外蒙皮厚度、内蒙皮缠绕角度以及外蒙皮缠绕的变化规律。研究结果表明：（1）当内外蒙皮的缠绕角度都为 90°时，空间点阵结构的载荷质量比最低；（2）当内外蒙皮的缠绕相同时，空间点阵结构的效率不是很高（3）当内外蒙皮的缠绕角度不同且选择适当时，空间点阵结构的载荷质量比可以更高。

Abstract

In order to attain composite lattice structures with high load-carrying efficiency

stability of composite circular lattice structures are analyzed by using FEM. Parametric design program is compiled with the APDL language of ANSYS. Changing law of load-to-mass ratio which is attached to thickness of inner skin

thickness of outer skin

winding angle of inner skin and winding angle of outer skin is researched by utilizing the design program . As a result

when winding angles of inner skin and outer skin are equal to 90 degree

load-to-mass ratio of circular lattice structures is the lowest. In addition

when winding angles of inner skin and outer skin are the equal value

effi ciency of lattice structures is not too higher. When winding angle of inner skin and outer skin are not the equal value

and are appropriately selected

load-to-mass ratio of lattice structures can be more higher.
