Abstract

The advancement of the aerospace industry necessitates the implementation of deployable space mechanisms. Spaceborne planar antennas must exhibit high stiffness, exceptional precision, and robust stability to withstand the harsh conditions of the space environment. This research introduces the design of the modular array deployable antenna (MADA) mechanism. A multi-vertex hybrid crease basic unit with three degrees of freedom (DoFs) is developed, consisting of one Waterbomb-Origami (Waterbomb-Ori) basic unit and four Miura-Origami (Miura-Ori) basic units (1W4M). Employing thick-panel origami theory, a zero-thickness model of the 1W4M crease basic unit is systematically constructed. Based on this model, the MADA mechanism is proposed. A kinematic model of the MADA mechanism is derived using the closed vector method. The theoretical results are validated through simulation studies. A dynamic model of the MADA mechanism is established, and the deployment process is optimized according to mechanism equilibrium theory to improve operational stability. Finally, a prototype of the MADA mechanism is fabricated, and agreement between real models and numerical simulations demonstrates the ability of the proposed methodology to confirm its practical feasibility.

基于1个水弹- ori和4个Miura-Ori基本单元机构的模块化阵列展开天线机构设计与分析

航空航天工业的发展需要实施可展开的空间机制。星载平面天线必须具有高刚度、超高精度和强大的稳定性，以承受恶劣的空间环境条件。介绍了模块化阵列可展开天线（MADA）机构的设计。提出了一种三自由度的多顶点混合折痕基本单元，由1个Waterbomb-Origami （Waterbomb-Ori）基本单元和4个Miura-Origami （Miura-Ori）基本单元（1W4M）组成。运用厚板折纸理论，系统构建了1W4M折痕基本单元的零厚度模型。基于该模型，提出了MADA机制。采用闭向量法建立了MADA机构的运动模型。通过仿真研究验证了理论结果。建立了MADA机制的动态模型，并根据机制均衡理论对部署过程进行了优化，提高了运行稳定性。最后，制作了MADA机构的原型，实际模型与数值模拟结果吻合，验证了所提方法的实际可行性。
