摘要
太阳模拟器的主要设计指标包括辐照强度、辐照均匀性、辐照稳定度及太阳光谱的匹配,然而太阳真实发射的平行光束有一定的张角(准直角),在日地平均距离处太阳的准直角为±16′,设计一高准直的太阳模拟器才能最真实反映外空间的太阳辐射,目前这种高准直太阳模拟器的研究较少,该文对准直角为±16′的太阳模拟器进行详细设计,具体指标达到辐照面积Φ50 mm,不均匀度为±8%,不稳定性为±5%/h,辐照强度达到0.1 S。
There are four basic design indexes matching to the solar simulator, including radiation intensity, radiation uniform, radiation stability and solar spectrum. The real sun emits parallel beams with a certain angle which is called collimation angle. The sun＇s collimation angle is ±16′ at the average distance of the sun-earth. A high collimation solar simulator which can perform the real out space solar irradiation is needed. Currently there are few researches on the high collimation solar simulator. A solar simulator with ±16′ collimation angle is designed. The radiation surface is Ф50mm, the radiation nonuniformity is ±8%, the radiation unstability is ±5%/h, and the radiation intensity reaches 0. 1S.
