本文针对某空间遥感器一重要光学元件即反射镜组件进行了结构设计。该反射镜的结构特点是长宽比大且口径大，经过优选反射镜材料、认真分析矩形反射镜支撑特点及对反射镜支撑定位原理的仔细研究，提出了一种基于半运动学定位原理的柔性支撑方案，即背部三点支撑加三点辅助定位的复合支撑形式，并应用计算机仿真手段进行了静、动态及热特性分析。经试验验证，方案合理可行。该方案普遍适用于大长宽比的大口径的反射镜，解决了大长宽比大口径反射镜结构支撑难题。

For a structure design of a space camera’s reflector, the reflector’s characteristic is big rectangle and big caliber. Based on optimization material, analyze rectangle reflector’s support characteristic, study reflector’s support theory, put forward a new flexible support based on half kinematics theory, namely a complex support form that three point on backside and three accessorial point, and analyze statics, dynamics and thermal characteristics by computer. It is tested that the project is reasonable and suitable for the big rectangle and big caliber reflector. We settle a difficult problem of the big rectangle and big caliber reflector’s support.
