针对目前国内外设计的太阳模拟器外形过于庞大不易携带等问题，本文设计了一种小型太阳模拟器。首先通过触发器提供一个高电压来使氙灯气体电离进入等离子态，从而将位于抛物面反光镜焦点处光源（短弧球形氙灯）点亮并通过抛物面反光镜会聚出射平行光束，通过氙灯光源调焦机构来使光源离焦，最终，在辐照面形成一个辐照度均匀分布的照射。通过对比，本文设计的太阳模拟器更加便携，能为室外等复杂地貌进行试验带来更多便利。结果表明，在工作距离300mm处，其辐照强度调节范围为546~1050.8W∕m2，辐照不均匀度为±12.5%，满足辐照强度在0.6~0.9kW/m2之间、辐照不均匀度≤±20%的设计要求。%For the design of a solar simulator at home and abroad too big appearance difficult to carry, and other is-sues, we design a small solar simulator. First through triggers provides a high voltage xenon lamp ionizes the gas into a plasma state, which will be located in a parabolic mirror at the focal point light source (short arc spherical xenon lamp) is lit by a parabolic mirror converging exit parallel beam by xenon light source focusing mechanism defocus the light source to the end,is formed in the irradiated surface irradiated with a uniform irradiance distribution. By contrast, the paper design of a solar simulator is more portable, can be tested for the outdoor complex topography bring more convenience. The results showed that the working distance of 300mm at its radiation intensity adjustment range of 546~1050.8W/m,the irradiation unevenness of ±12.5%,to meet the radiation intensity ≥0.6kW/m2 and <0.9kW/m2,radi-ation according unevenness ≤±20% of the design requirements.
