摘要
固面反射面因具有非常高的型面精度而广泛应用于卫星的口径天线。针对目前常用的花瓣式旋转固面可展开天线因具有较多的转动副而影响其整体可靠性的问题,探究了固面可展开天线绕正交双轴旋转与绕单轴旋转的等效变换原理及相应的设计方法,并通过实例验证了绕单轴旋转的有效性。结果表明绕单轴旋转的设计减少了花瓣式旋转可展开天线转动副的数量,提高了天线的整体稳定性和展开可靠性,这对固面可展开天线的设计和分析有重要的参考价值。
Solid-surface reflector is widely used in satellite aperture antenna because of its high surface accuracy.Aiming at the problem that the overall reliability of the petal rotation solid-surface deployed antenna is affected by the large number of rotating pairs,the equivalent transformation principle and the corresponding design method of the solid-surface deployed antenna rotating along two orthogonal axes and a single axis were investigated,and the effectiveness of deployed antenna rotating along a single axis was verified by an example.The results showed that the number of rotating pairs of petal rotating deployed antenna was reduced to improve the overall stability and deployable reliability of the antenna,which is of great reference value for the design and analysis of solid-surface deployed antennas.
