摘　　要：为提高航天器载荷比,降低平台质量,针对航天器低频电缆网减重的现实需求,提出采用矩阵电缆网实现航天器遥测、遥控信号电缆减重的新途径。为最大程度优化矩阵电缆的设计方法,首次建立了基于无向图的矩阵电缆网数学模型,提取了影响电缆质量的两项要素——拓扑结构与矩阵资源分配方式,同时引入遍历顺序的概念,实现了两项要素的有机结合。文章提出了资源分配的优化设计原则,并进行了工程算例仿真,结果表明,优化的矩阵电缆网较离散电缆网减重约50%,并且增加了系统备份,有效提升了传输系统的可靠性。In order to improve the payload ratio of spacecraft and reduce the weight of the platform,this paper presents a new way to reduce the harness weight by using matrix control and telemeter harness.To optimize the harness design method to the greatest extent,a mathematical model of matrix harness based on undirected graph was established.Two factors affecting harness weight lose were extracted by the model:topology and matrix resource distribution.The concept of visiting order was introduced in the paper,and the organic combination of the two factors was realized.Basic principles for optimization design were presented,and simulation verification was carried out.The results show that the optimized matrix harness weight is about 50% less than the discrete harness weight,improving the system reliability effectively.
