为了给不宜翻转安装、不宜被旋转的航天太阳跟踪产品提供模拟太阳光,提出了调整反射镜姿态的动态太阳光模拟方法,设计并实现了单自由度太阳光模拟系统。系统包括太阳模拟器、运动台、平面反射镜、编码器、光栅尺、电机和控制系统等。系统通过同时调整平面反射镜的水平位移和倾角,将模拟太阳光总是投射到航天太阳跟踪系统中的太阳敏感器处,保证了航天太阳跟踪产品在模拟太阳光照试验中完全自主运动,不被转动或翻转安装,保护了航天产品中的敏感机械组件。系统建立的光照环境贴近真实太阳光照,便于航天太阳跟踪产品调试和测试。试验结果表明,单自由度太阳光模拟系统可满足航天太阳跟踪产品的测试需求,模拟太阳光入射偏差为0.6984mm。
In order not to flip the installation should not be rotated by the space solar tracking products to provide simulated sunlight, the proposed adjustment of the mirror attitude of the dynamic solar simulation method, design and implementation of a single degree of freedom solar simulation system. The system includes solar simulator, motion stage, plane mirror, encoder, encoder, motor and control system. By adjusting the horizontal displacement and inclination of the plane mirror at the same time, the system always projects the simulated sunlight onto the sun sensor in the aerospace sun tracking system, ensuring that the aerospace sun tracking product completely autonomously moves in the simulated sunlight test without being disturbed Turn or flip the installation to protect sensitive mechanical components in aerospace products. The system establishes a light environment that is close to the true sun’s illumination for easy commissioning and testing of aerospace sun-tracking products. The experimental results show that the single degree of freedom solar simulation system can meet the testing requirements of aerospace solar tracking products, and the deviation of simulated solar incidence is 0.6984mm.
