摘　　要：为了对某相机进行热平衡试验,并克服传统太阳模拟器结构复杂、成本较高、光效利用率低的缺点,提出了将太阳模拟灯阵整体放在真空罐内使用的研制方案。首先,对该方案所需解决的各种问题进行了理论分析,计算得出模拟灯阵的辐照度要求为635.2～905.4W/m2,光学系统效率为0.1444。分析了真空罐液氮冷却系统的导热能力,结果显示,该冷却系统温度升高ΔT为2.0741K,小于其过冷度4K,表明该冷却系统可以将太阳模拟灯阵灯的热量导出。对系统热设计进行了分析和讨论,结果表明,积分器和反射镜的温度在200℃左右,氙灯灯极温度在92℃左右,满足其长时间正常工作的条件。最后,测试了模拟灯阵的技术参数,结果显示其照度为490.37～1000.56W/m2连续可调,辐照不均匀度<±5%,辐照不稳定度<±5%/h,各项指标均满足设计指标要求。In order to do the thermal balance tests for some type space-cameras and to overcome the shortcomings of traditional solar simulators in complicated structure, high costs and low light efficiencies, a simulated solar Xe flash-lamp array placed in a vacuum tank was developed. The theoretical principles of the simulated solar lamp array were analyzed, then it pointed out that its irradiance should be set to 635.2-905.4 W/m^2 and its efficiency of optical system is 0. 144 4. The heat conduc tion ability of the liquid nitrogen cooling system in the vacuum tank was analyzed, and the results indicate that the temperature of cooling system in the vacuum tank AT is 2. 0741 K and lower than a super cooling temperature of 4 K, which means that the liquid nitrogen cooling system can export the heat of solar simulated lamp array out from the vacuum tank. The thermal design of the simulated lamp was analyzed and discussed, results show that the temperatures of optical integrator and mirror are all around 200℃ , and the temperatures of cathode and negative electrodes of the lamp are around 92℃, which meets their normal working conditions for a long time. Finally, the technological specifications of the simulated solar lamp were tested, it is shown that its radiation intensities are 600-1000 W/me, and the inuniformity and unsteadiness of radiation are less than ±5% and ±5%/h, respectively. Those data are well coincident with the design targets
