Abstract  Presents a new architectures of the reflect array antenna, it is useful to reduce the weight and the volume of antenna when it is un-deployed. In order to mitigate the wrinkle, the shape of the cable was proved to be a circle. A detailed method of computing the cable system was introduced. The most fundamental structural component of this antenna is the spring tape reinforced aluminum laminate inflatable boom. The correctness of the nonlinear buckling analysis was proved by experiment. The influence of the thickness, the central angle of the spring tape and the thickness of the aluminum laminate to the supporting capacity of the boom were studied. At the end, this new type reflect array antenna was made, the surface precision of this antenna was measured, the result shows that this kind of new type antenna is suitable for application.

新型折叠卷收式反射阵天线的设计与制作

设计了一种新型折叠卷收式反射阵天线，减少了天线展开前的质量和体积．为了使反射面得到最好的平面精度，从理论上证明反射面的边界形状应当为圆形．给出了悬索详细的设计计算方法．在此结构中使用了一种新型的、通过钢卷尺强化的充气可展开铝箔圆管．通过非线性屈曲分析，研究了钢卷尺的厚度、圆心角角度以及铝箔厚度等因素对圆管承载力的影响，并通过实验验证了非线性屈曲分析结果的正确性．最终制作了这种新型天线，并对其展开后的形面精度进行了测试，实验证明此种新型天线完全可以满足反射阵天线的精度要求．
