英文摘要	To meet the requirements of a large-scale space infrared camera for a lighter weight and higher rigidity framework with complex support function, a framework entirely formed by trusses was designed. Then, the feasibility and reliability of the frame were demonstrated by structure analysis, technological test and mechanical test. The framework was combined by 58 carbon fiber struts and 21 joints to form the main support structure of the camera. It could support most of optical modules in circumference distribution and could meet the weight requirement less than 55 kg. The methods and steps for gluing the subassemblies were described particularly, then the finite element analysis and mechanical experiment were used to verify that the triangle enclosed truss structure in stress state could offer an adequate safety margin even if the adhesive strength was reduced. Mechanical experiment results show that the basic frequency of the framework is 90.4 Hz, which is consistent with the results of finite element analysis and higher than the limited frequency of 60 Hz. 2017, Science Press.
