| Abstract: | To get the lightweight structure of fast steering mirror to meet design requirements through structural optimization and treatment. The appropriate processing material was selected. The optimization mathematical model was established with minimizing the structural flexibility as the optimization objective. New model after optimizing was studied by numerical simulation analysis. The reasonable structure was obtained through optimization and analysis. Results showed that the maximum deformation of the mirror reached 2.7 nm and the fundamental frequency was 4130.3 Hz, both of which sufficed requirement of the design. The structural weight was lower by 57.8% after optimization than before. The results of optimization are satisfactory, which can be used as reference for the design of similar structures. |
