摘　　要：高辐照度太阳模拟器是太阳能高温试验研究中的关键设备。传统的太阳模拟器光源阵列采用固定式环状排列结构,只能沿光轴方向投射出平面光斑。该文研究玻璃光纤为传输辐射的介质,开发出一种灵活的高辐照度太阳模拟器,并通过通量映射方法对太阳模拟器的辐照性能进行验证。实验结果表明该太阳模拟器可通过改变光纤束的布置方式在2D和3D空间中得到不同的辐照度分布。The high irradiance solar simulator is a key equipment in solar high temperature experimental research. The traditional solar simulator light source array adopts the fixed circular arrangement structure,and can only output the flat spot along the focal axis direction. In this study,a flexible high-irradiance solar simulator was designed by using glass optical fiber as the medium for transmitting radiation,and the radiation performance of the solar simulator was verified through the flux mapping method. Experimental results show that the simulator can realizes different irradiance distributions in two-dimensional and three-dimensional spaces by changing the arrangement of optical fiber bundles.
