摘要复合材料薄壁圆管铰链在卫星天线、太阳翼等大型航天可展结构中具有广阔的应用前景，其结构参数设计极大地影响它在空间的工作性能。为提高复合材料薄壁圆管铰链的力学性能，本文首先建立复合材料卷尺弹簧的解析和有限元模型，分析其弯曲特性，进而建立复合材料薄壁圆管铰链的有限元模型并研究其折展和扭转特性，分析结构参数对铰链性能的影响规律，结果表明，增大开槽长宽比、减小铰链厚度直径比可以明显提高铰链的弯曲和扭转性能。选取铰链结构参数为设计变量，建立多目标优化数学模型，结合最优拉丁超立方试验设计方法，建立结构参数与铰链峰值弯矩、最大应力、扭转刚度之间的RBF神经网络代理模型，通过NSGA-Ⅱ遗传算法进行优化。优化结果表明，铰链的峰值弯矩提高44.8%，扭转刚度提高110%，同时质量下降20.4%，在提高复合材料薄壁圆管铰链力学性能的同时实现了轻量化，使得铰链机构的自驱动能力和自锁定能力有了全面的提高，为复合材料薄壁圆管铰链在空间可展开结构中的实际工程应用提供了理论依据。

Abstract：Composite thin-walled circular tube hinges have broad application prospects in large space deployable structures, such as, satellite antennas and solar wings, and their structural parametric design greatly affects their working performance in space. Here, in order to improve their mechanical performance, firstly, the analytical and finite element models for a composite tape measure spring were established to analyze its bending characteristics. Then the finite element model for a composite thin-walled circular tube hinge was established to study its folding and torsional characteristics and analyze effect laws of structural parameters on the hinge performance. The results showed that increasing the ratio of slotting length to width and reducing the ratio of hinge thickness to diameter can obviously improve the hinge’s bending and torsional performance. The hinge’s structural parameters were taken as design variables to build a multi-objective optimization mathematical model. The optimal Latin hyper-cubic test design method was used to construct the RPF neutral network agent model among structural parameters and hinge’s peak bending moment, maximum stress and torsional stiffness, and it was optimized using the NSGA-Ⅱ genetic algorithm. The optimization results showed that the hinge’s peak bending moment is increased by 44.8%, its torsional rigidity is increased by 110%, and its mass is decreased by 20.4%, so the hinge’s mechanical performance is improved and meanwhile its mass is reduced to enhance the hinge mechanism’s self-driving ability and self-locking one; the study results provide a theoretical basis for practical engineering application of composite thin-walled circular tube hinges in space deployable structures.
