In order to realize the on-orbit expansion of the space segmentation mirror and the fine adjustment of the mirror surface, a dynamic support mechanism is designed. And its adjustment mechanism is analyzed. Firstly, the dynamic support mechanism is designed and modeled. Then, the inverse calculation of the support mechanism pose is analyzed. Finally, a finite element analysis of the established model is carried out, and compared with the experimental results. The results show that the space segmentation mirror has the ability to be assembled into a large-caliber telescope on orbit and to ensure image quality.
