KFTA太阳模拟器辐照均匀性仿真

文章着重介绍了太阳模拟器光学系统及氙灯的建模,尤其对短弧氙灯建模做了详细阐述,它是根据短弧氙灯的亮度分布图采用多个体光源嵌套的形式模拟氙灯,用角度切址文件和光谱分布数据定义短弧氙灯的角度分布和光谱分布。最后运用美国ORA公司的光学分析软件LightTools对太阳模拟器辐照均匀性进行仿真计算,并得到辐照度的一维、二维和三维图形。

Irradiation Uniformity Simulation of KFTA Solar Simulator

This paper lays stress on the establishment of the optical system model of solar simulator and xenon short arc lamp model, especially the later. Based on luminance distribution graph of xenon short arc lamp, a set of nested cylindrical or spherical volume sources is used to simulate xenon short arc lamp, and angular apodization files and spectral distribution data are used to define the angle distribution and the spectral distribution. Finally, the optical analytical software Light Tools of ORA from the USA is used to analyze irradiation uniformity of KFTA soar simulator. And one dimensional, two dimensional and three dimensional graphs are obtained.
