Abstract

According to the design requirements of a certain silicon carbide mirror, a parameter structure model of the mirror has been established using the finite element method. Then the sensitivity analysis and sizing optimization is applied to the eight structural parameters of the mirror and the optimum size is gained. The results have shown that the lightweight ratio of the optimum mirror is about 52.5%, and the WFE is satisfactory with the design requirements. Furthermore, the effects of different temperature levels, the axis and radial temperature gradient on the optimum mirror surface figure are also analyzed. It is also found that the deformation of the mirror is concerned with the magnitude and direction of temperature gradient directly.
