讨论了某新型周边桁架式展开天线拉索系统的布局优化设计问题.将天线拉索系统的上、下悬索数量,以及中间调节索数量作为设计变量,在优化过程中主要考虑结构拉索系统原理精度约束,建立以结构重量最轻为优化目标,基于天线几何精度的展开天线布局优化数学模型.通过数值算例证明,拉索系统的布局优化设计对提高天线设计质量是非常有效的.
This paper discusses the layout optimization design of a new type of surrounding truss-type antenna system with cable as the design variable, taking the number of upper and lower suspension cables and the number of intermediate adjustment cables as the design variables in the cable system, Principle and precision constraint, a mathematic model of antenna layout optimization based on antenna geometry accuracy is established, which is optimized with the lightest weight of the antenna.The numerical example shows that the layout optimization of cable system is very effective to improve the design quality of antenna.
