摘　　要：反射镜支撑结构在空间力学和热环境下良好的稳定性是保证反射镜成像质量的关键。本文针对空间光学遥感器反射镜设计了一种反射镜支撑结构。由于刚性支撑结构不能满足热环境下的面形要求,进而设计了一种柔性支撑方案。通过有限元模型分析,表明该支撑结构力学以及热环境下均可以保证反射满足面形要求,验证了该方案的合理性。Fine stability is the key factor of imaging quality to the optical reflector of space remote sensor under the environment of force and thermal constraints. Based on a space remote sensor, a support structure of a space optical reflector is designed. Results indicate that solid support structure can＇t meet the demands of imaging quality, so a flexible support structure is designed. The finite element analysis show that the surface accuracy of reflector meets the needs of imaging quality due to regulation of flexible structure under the environment of force and thermal constraints. Analysis and test results demonstrate that the flexible support structure is reasonable.
