从概念设计到测试，对直径4至50米、射频频率高达ka波段的大型可展开反射器结构进行了技术评估。已经开发了参数化有限元分析工具来研究这些概念的静力、模态和屈曲行为。根据所选的概念设计和获得的分析结果，设计、制造和测试了基于外圈结构的直径分别为1.6 m和4 m的完整面包板。两种面包板的测试结果均满足部署可重复性、精度和可扩展性的要求，从整体上证明了可展开环设计和大型可展开天线概念的成功选择。
The technical assessment of large deployable reflector structures covering a diameter range from 4 to 50 m and RF frequencies up to Ka-Band is presented from the conceptual designs to the tests. Parametric FEM analysis tools of the concepts have been developed to study their static, modal and buckling behaviors. According to the selected conceptual design and acquired analysis results two complete breadboards with diameters of 1.6 m and 4 m based on a peripheral ring structure have been designed, manufactured and tested. Test results of both breadboards fulfilling the requirements on deployment repeatability and accuracy as well as scalability demonstrate the successful selection of a deployable ring design and large deployable antenna concept in whole.
