Research on factors affecting the assembly accuracy of deployable arms

Abstract

A spacecraft deployable arm is one of the key components of spacecraft. The assembly accuracy of space deployable arms restricts the improvement of spacecraft performance. Therefore, it is important to analyze the factors influencing the assembly accuracy of deployable arms to optimize the assembly process. This paper studies the precision assembly of deployable arms, with a spacecraft deployable arm as the specific research object. In the study, the assembly process is modeled theoretically and analyzed by Finite Element Analysis. Finally, the assembly experiment of the deployable arm is carried out based on the research.
