摘　　要：从满足某空间光学遥感器主镜在复杂的工况下综合面形误差要求的角度出发，介绍了长圆形主镜及其支撑结构材料的选择。讨论了主镜的优化设计及其支撑结构的设计方法，并运用CAD／CAE工程分析软件对其进行了分析及优化，应用有限元法优化出了一种合理的主镜柔性支撑结构。In order to meet the requirements of the integrated precision of the primary mirror segment used for space minitype camera, selection of the materials of primary mirror and supporting structure is introduced. The design method of the supporting structure of the mirror is proposed. The analyzing and optimizing are put up through CAD/CAE engi- neering analysis software. A sort of reasonable flexible supporting structure reflected mirror is optimized by means of fi- nite element method （FEM）.
