Abstract
With high resolution, low cost and short manufacturing cycle, the optical load of aluminum–based has attracted more and more attention from researchers. In this paper, the optical system is briefly introduced and the tolerance analysis is carried out. Secondly, the whole structure of aluminum space camera is designed. The main mirror adopts integrated design method to reduce two-stage assembly. In order to ensure the assembly is simple and reliable, the whole machine adopts cylinder support. Then, the structure of the integrated main mirror is optimized, the lightweight rate reaches 30%, and the machine's quality is 1.8kg. Finally, the mechanical characteristics and temperature adaptability of the whole machine are analyzed by means of finite element analysis. The analysis results show that the system's MTF value is more than 0.2 at 20±5°C temperature and static environment, which meets the imaging requirements; and each mode is larger than 100Hz, satisfying the dynamic requirements.
