摘　　要：为探究太阳辐射对冰生消过程、力学特性及冻土冻融传热变化规律影响,分别开展光源选择、系统设计和性能测试等试验,设计一种可在室内模拟辐照条件的太阳模拟器。结果表明,碘钨灯与白炽灯色温均小于野外太阳光色温,金卤灯和长弧氙灯色温与野外太阳光色温相差较小,而长弧氙灯光谱中各波段能量分布占比与野外太阳光接近,可在测试波长范围内满足B级模拟器要求;灯架选材为强度大且不易锈蚀的白钢方管,同时考虑光照稳定性,设计两层结构灯架并布置方形灯阵;太阳模拟器在有效辐照面范围内1 m高度处辐照度达115 W·m^-2,同时模拟器辐照不均匀度和不稳定度均符合模拟器等级中B级要求。因此,设计太阳模拟器满足主要技术参数及要求,可用于室内模拟辐照环境,为太阳辐射对冰生消过程及冻土传热规律影响研究提供理论支持。In order to explore the influence of solar radiation on the process of ice generation and extinction,the study of mechanical properties and the change rule of freezing-thawing heat transfer in permafrost,experiments such as light source selection,system design and performance test were carried out,respectively,and a solar simulator which could simulate the radiation conditions in the room was designed.The results showed that the color temperature of iodide tungsten lamp and incandescent lamp was lower than that of field sunlight,while the color temperature of metal halide lamp and long-arc xenon lamp was not different from that of field sunlight,while the energy distribution ratio of each band in the spectrum of long-arc xenon lamp was closer to that of field sunlight,and it met the requirements of B-class simulator within the full wavelength range.The material of the lamp holder was the white steel square tube with high strength and not easy to rust.At the same time,considering the light stability,the lamp holder was designed into a two-layer structure and the lamp array was arranged into a square.The irradiance of the solar simulator was up to 115 W·m^-2 at a height of 1 m within the range of the effective irradiation surface.Meanwhile,the irradiation inhomogeneity and instability of the simulator met the B-level requirements of the simulator level.Therefore,the solar simulator was designed to meet the main technical parameters and requirements,and could be used to simulate the indoor radiation environment,so as to provide a theoretical support for the research on the influence of solar radiation on the ice generation and extinction process and the heat transfer law of frozen soil.
