Abstract: The long-distance deployable arm with large space load is recognized as a critical component for large space loads such as large-scale spaceborne antennas and radar systems. To ensure superior pointing and positioning accuracy, foldable hinge rod-type deployable arm is selected as the research focus. Key research efforts are directed toward the identification of precision-influencing factors, development of comprehensive analytical methodologies, and implementation of ground-space consistency validation protocols. Systematic investigations are conducted to analyze critical precision-determining mechanisms and their variation patterns. A comprehensive methodology for precision-oriented design and control is established, with high-fidelity ground simulation validation and experimental verification being systematically implemented. Integrated precision control is ultimately achieved for in-orbit high-precision operation of long-distance deployable arm with large space load. These findings are considered to provide valuable guidance and reference significance for both precision-oriented design and engineering implementation of large-scale space deployable mechanisms.

Key words: deployable arm, precision design, thermal deformation, zero-gravity offloading
