| 摘 要： | 文章主要针对形状复杂的月球探测器的热流模拟问题进行研究。基于遗传算法与复合形算法，采取双目标、变尺度网格的优化策略建立了红外灯阵热流优化设计方法。应用单灯热流分布计算模型生成单灯热流分布数据库，解决了反光板反射热流问题，在此基础上建立了红外灯阵热流分布仿真计算方法。结果表明热流分布仿真计算具有较高的准确度，速度快，能够满足优化设计的需要，可以有效提高热流分布均匀性。

| Abstract: | This paper presents the simulation of heat flux on complex-shaped lunar detector in thermal tests.The optimization design of infrared lamp array is realized by using duel-objective and variable metric grid strategy based on genetic algorithm and complex algorithm.The heat flux distribution database is generated based on the calculation of the heat flux distribution of a single lamp.The problem of the heat flux reflection from the reflective baffles is thus solved.A simulation method for calculating the infr... |
