| 摘 要： | 文章基于蒙特卡罗-区域分解法，建立太阳模拟器内复杂几何构型卫星稳态温度场数学模型；利用数值模拟求解卫星表面太阳辐照面积、红外和太阳辐射传递系数，得到不同辐照条件下卫星的温度分布；分析太阳辐照的非均匀性和不稳定性对温度分布的影响。计算结果表明:蒙特卡罗-区域分解法对于太阳模拟器模拟空间外热流的仿真研究是一种非常有效的方法；太阳辐照非均匀性对温度分布的影响大于不稳定性所产生的影响。

| Abstract: | A mathematical model for the steady temperature field in a satellite with complicated structure is established in the paper based on Monte Carlo-Domain Decomposition(MC-DD) method. The solar incident areas, infrared and solar radiation transfer coefficient of surfaces are numerically simulated. The temperature distribution in different solar irradiation conditions and its variation affected by non-uniform and instability of solar irradiation in solar simulator are calculated and analyzed. The results show that the model is effective for studies on space outer-heat-flux simulated by solar simulator, and the effect of non-uniform solar irradiation on the temperature distribution is shown to be greater than that of the instability. |
