Abstract: Centering on the structural mechanism technology in the on orbit construction of space optical telescope, this paper focuses on the basic concepts and technical characteristics of key technologies related to structure and mechanism, including topology optimization and module technology of space structure of large telescope, high precision deployment adjustment and locking technology of optical mechanical structure and mechanism, on orbit additive manufacturing technology of typical optical mechanical components. It also analyzes the technical connotation and advanced technical approaches of robot assisted autonomous precision assembly and control technology. Finally, the development trend of structure and mechanism technology in on orbit construction and some technical problems to be studied are prospected. This paper may provide a reference for evolution of space optical telescope.
