英文摘要	To meet the requirements of the near-surface telescope's high surface accuracy and 0-65 observation angle, a 816-mm SiC aperture primary mirror assembly was designed. The design of the primary mirror was completed according to the empirical formula and topology optimization method. Based on the principle of compound support of large-aperture mirrors and the methods of function allocation and index allocation, a primary mirror support assembly was designed, and decoupling standards were formulated. According to the supporting structure and assembly tolerance design requirements for the primary mirror component assembly tooling and assembly process. Finite-element software was used to verify the statics and dynamics of the primary mirror assembly, and the primary mirror assembly was verified by performing experiments such as vibration, surface shape detection, and inclination. The test results show that the primary mirror assembly is at the optical axis level, RMS value of the profiling accuracy under the action of 1 g gravity is 0.019 (=632.8 nm), and RMS of the surface shape after the mirror is turned by 180 is 0.02. The total mass is 102.7 kg, fundamental frequency is 171 Hz, and RMS values before and after vibration are unchanged, which is consistent with the analysis results. The results proved that the design and installation process of the composite support are reasonable, and that they meet the design requirements of near-space telescopes. 2021, Science Press.
