摘要

由于载荷变化及各种随机干扰

大型空间桁架面天线必须保持非常精确的形状.基于提高空间天线电磁性能以及降低作动器能耗的目的

结合大型空间桁架天线结构的特点

建立了以天线轴向增益和作动器能耗为目标函数

以结构强度、作动器变形和轴力为约束条件的多目标优化模型.数值试验结果表明

结构—电磁耦合优化设计模型只需较低的作动器能耗

就能明显提高天线电性能

很好地满足了天线结构与电磁设计要求.

Abstract

To obtain an extremely high accurate surface precision and the electromagnetic performances

the large space parabolic antennas with truss structures should have special characteristics.A mechatronic optimization design model of space antenna structures is developed for the improvement of the electromagnetic performances

which adopts the axial gain of antenna and power consumption of actuators as the objective functions

and the material strength of bars and actuator’s mechanical capability as constraint conditions.The two applications of optimization model to truss antenna structures demonstrate the potential for the significant improvement of antenna performances.The analysis results indicate the benefit of including the electrical performance in optimization model for necessary effort for shape control of large space antenna reflectors.
