| Abstract: | A method for space scanning mirror structural design is introduced,which uses a multi-parameter optimization algorithm based on FEM. The structural parameters and design requirements of the space scanning mirror are defined as design variables,constraint functions and objective function. Optistruct is used for size and shape optimization. The results show that it meets the requirements well. The sensitivity analysis is quite useful for modifying the design. |
