摘　　要：传统航天器热控系统只能在特定输入条件下才能保持理想输出,自适应热控系统则具备较高鲁棒性,自适应热控技术的动态热分析技术是其设计与应用层面的关键技术。基于航天器热分析软件求解原理,提出了自适应热控技术的动态热分析方案;针对辐射、对流和导热三类自适应热控技术的热控方式及仿真特性,提出了各类自适应热控技术的动态仿真能力需求及具体仿真方案;对各类动态热分析方案进行了可行性分析。所提出的航天器动态热分析技术对自适应热控技术设计及其应用研究具有指导意义,对高适应能力热控体系研究与方案设计具有重要价值。The traditional spacecraft thermal control system can only maintain ideal output under certain input conditions. The self-adaptive thermal control system is of high robustness, and the dynamic thermal analysis technology of adaptive thermal control technologies is the key technology in the aspects of design and application. Based on the principle of thermal analysis software, a dynamic thermal analysis scheme of adaptive thermal control technologies was put forward. The capacity requirements and specific schemes of dynamic simulation were put forward based on the thermal control mode and simulation characteristic of radiation, convection and conduction adaptive thermal control technologies. The practicability of each scheme was further analyzed. The dynamic thermal analysis technology is of instruction significance to the adaptive thermal control design and application research, and great value to the system analysis and scheme design of high adaptive thermal control system.
