摘要

承力筒是卫星的主要承力部件，对整体结构承载性能具有重要作用。纤维缠绕 Kagome 网格式承力筒有质轻高强的特征，是卫星承力筒常用的结构。但网格结构设计中，结构参数之间相互耦合，对网格承载性能的影响尚不清晰。本文针对纤维缠绕 Kagome 网格卫星承力筒，开展结构优化研究。首先采用有限元建模方法，对卫星特定工况下的承载性能进行分析，提出螺旋筋及环筋相对独立的设计思想，结合参数化建模策略，获得各个结构参数对承载性能的作用规律；其次采用多目标遗传算法，以承载性能及质量为主要优化目标，对承力筒结构参数进行优化，并分析了最优结构的强度和屈曲性能。结果表明，最优结构质量降低了 21.2%，力学性能满足卫星特定工况条件；最后采用自主研制的桌面式缠绕机对网格承力筒进行了缠绕成型。

Abstract

Cylinder is the main bearing component of a satellite

which plays a major role in the load-bearing performance of the whole structure. Due to lightweight and high strength

Kagome grid satellite cylinder made by filament winding is commonly used in satellite cylinder. However

the structural parameters are coupled with each other in the design of the grid structure

and the effect of the parameters on the load-bearing performance of the cylinder is unclear. In this paper

the structure optimization of the Kagome grid satellite cylinder is studied. The finite element method is used to analyze the load-bearing performance of the cylinder under the working conditions for the satellite. Furthermore

the relative independence design conception regarding spiral rib and ring rib is put forward. Combining the parametric modeling strategy

the effect of each structural parameter on the load-bearing performance is obtained. With the loadbearing performance and mass as the main optimization objectives

the structural parameters of the cylinder are optimized using the multi-objective genetic algorithm. Also

the strength and buckling performance of the optimal structure are analyzed. The results show that the mass of the optimal structural is reduced by 21.2%

and the mechanical properties meet the specific working conditions of the satellite. Finally

the self-developed desktop winding machine is used to wind the cylinder.
