Abstract Deployable solid-surface reflectors have been widely employed as the main part of antennas or telescopes in space observation and communication missions. The petal-type deployable solid-surface reflector has better package ratio and deploying properties. In order to balance the contradiction between simplification for mechanism reliability and development for structural stability, the petal-type deployable solid-surface reflector has been developed by a uniaxial rotation mechanism. This uniaxial rotation mechanism is deduced to fulfill the equivalent movement of New Petal-type Deployable Solid Surface Antenna (NPDSSA) by two orthogonal rotation mechanism based on Rodrigues Rotation Formula and Euler Angle Transformation Matrices. The general expressions of axis vector and rotation angle for uniaxial rotation mechanism are obtained to conduct parametric modeling. The 1.2-m aperture reflector as a case study is analyzed to explore kinetic properties of this model and the functions of the drag spring. It is indicated that this reflector by uniaxial rotation mechanism has a simpler mechanism and better kinetic properties than the original NPDSSA.

单轴旋转机构花瓣型可展开固体表面反射器的研制

摘要 可展开式固体表面反射镜在空间观测和通信任务中被广泛用作天线或望远镜的主要部件。花瓣型可展开固体表面反射器具有更好的封装比和展开特性。为了平衡机构可靠性的简化和结构稳定性的发展之间的矛盾，通过单轴旋转机构开发了花瓣式可展开固体表面反射器。基于罗德里格斯旋转公式和欧拉角变换矩阵的两个正交旋转机构，推导出这种单轴旋转机构来实现新型花瓣式可展开固体表面天线（NPDSSA）的等效运动。得到单轴旋转机构的轴矢量和旋转角度的一般表达式，进行参数化建模。以 1.2 米孔径反射器为例进行分析，以探索该模型的动力学特性和阻力弹簧的功能。结果表明，这种单轴旋转机构的反射器比原来的NPDSSA具有更简单的机构和更好的动力学性能。
