摘要

为模拟大面积空间太阳光辐照环境, 提出一种新型投影式太阳模拟系统设计方法。根据光学扩展量理论分析系统的能量传递过程, 采用4个短弧氙灯阵列作为光源, 设计物方远心投影系统以实现大面积均匀照明。通过Zemax软件模拟仿真及实际系统测量来验证系统设计的合理性。实验结果表明: 太阳模拟器的有效辐照面尺寸为1000 mm×1000 mm, 辐照度可达1263 W/m2, 且辐照面不均匀度优于±4.82%。该研究可为卫星载荷的空间环境实验提供准确可靠的太阳光辐照, 弥补传统大型太阳模拟器体积大、造价高的局限。

Abstract

In order to simulate the large-area solar irradiation in the space environment, a systematic design procedure for a new projection solar simulator is presented. Based on etendue theory, the energy transfer process of the system is analyzed. An array of four xenon lamps is used as light source. An object-space telecentric projection system is designed to realize a large area and uniform illumination. The simulation of Zemax software and the actual measurement for the system are carried out to verify the rationality. The results show that the effective irradiance surface of the solar simulator is 1000 mm×1000 mm, the irradiance can get 1263 W/m2, and the irradiance non-uniformity is less than ±4.82%. The solar simulator can provide a reliable solar radiation for the space environment test of satellites, which conquers the limitations of large size and high cost of the traditional large solar simulators.
