摘　　要：为解决现有太阳模拟器能量利用率低导致辐照度低的难题,依据太阳模拟器基本成像原理,提出利用复合抛物面聚光器(CPC)改进太阳模拟器的聚光系统.分析了CPC与传统聚光器的聚光机理,基于边缘光线原理推导了CPC的参数设计方法.利用LightTools软件结合嵌套的体光源与CPC建立聚光模型,分析了CPC理想最大接收角。建立椭球聚光镜与组合聚光系统的对比模型,验证了理论分析.通过截取分析得到最佳截取比来优化初始结构,进而确定CPC的最终结构.结果表明:氙灯应用在CPC中的能量利用率高达94.86%,且整个太阳模拟器的辐照度有很大提升.该研究能够为设计高能量利用率高辐照度的太阳模拟器提供参考.To solve the problem of low irradiance caused by the low energy utilization rate of an existing solar simulator,a Compound Parabolic Concentrator(CPC)based on the basic imaging principle of the solar simulator was proposed to improve the concentrating system of the simulator.The condensing mechanism of the CPC and a traditional condenser was analyzed,and the parameter design method of the CPC was derived based on the edge-ray principle.Using the LightTools software combined with a nested body light source and the CPC to build a condenser model,the ideal maximum receiving angle of the CPC was analyzed.A comparison model between the ellipsoidal condenser and the combined condenser system was established to verify the theoretical analysis.The optimal intercept ratio was obtained through an intercept analysis to optimize the initial structure and to determine the final structure of the CPC.Results show that the energy utilization rate of xenon lamps used in the CPC is as high as 94.86%.Furthermore,the irradiance of the entire solar simulator can be greatly improved.The findings of this study present a reference for designing highly energy efficient and high-irradiance solar simulators.
