摘　　要：针对传统太阳模拟器普遍存在辐照均匀度较低的缺陷,改进设计了一种可以有效提高太阳模拟器辐照均匀度的光学积分器.介绍了该光学积分器的组成和工作原理;阐述了光学系统的优化设计技术;对其光机结构进行合理化设计,并使用ansys软件对光机结构进行热分析.最后,利用lightTools软件对太阳模拟器系统进行模拟仿真.结果表明:使用所设计的光学积分器后,太阳模拟器辐照不均匀度明显降低,在Φ60mm范围内小于±1%,在Φ(60～200)mm范围内小于±2%.该结果与实际检测结果一致,能够满足高准确度的使用要求.Aiming at lower irradiation uniformity of the traditional solar simulator, an optical integrator is designed which can effectively improve the irradiation uniformity of sun simulator. The composition and working principle of optical integrator is introduced, optical optimization design technology of optical integrator is described, optical and mechanical structure of the optical integrator is designed reasonably, and the ansys software is used for thermal analysis of the machine structure. Finally, lightTools software is used to be simulating for solar simulator. The results show that： after using the optical integrator, irradiation non uniformity of the sun simulator is markedly improved, irradiation non uniformity in 60 mm range is less than ±1%,and in （60-200） mm is less than±2%, instability is better than ±1%/h, which agree with the test data and can meet the requirements of high-precision.
