Modeling and simulation of radioisotope power system based on digital mock-up
放射性同位素电源系统(RPS)是未来深空探测任务中不可或缺的能源系统之一.针对在役RPS逆向研究中,不同型号电源几何尺寸、结构设计及功率等级方面差异较大,导致仿真分析建模难、效率低等问题,提出了一种放射性同位素电源系统数字样机仿真技术.首先,对该RPS数字样机仿真技术的功能、研究技术路线进行了总结归纳.然后详细阐述了在役RPS逆向研究的热电耦合分析和辐射剂量分析的流程、方法和注意事项.将该仿真技术应用于GPHS-RTG、"嫦娥四号"RTG、MMRTG等典型电源的逆向研究,得到了上述电源在深空、星表环境下的热电性能、应用方案和辐射剂量分布等重要结果,证明了技术的可行性和普适性,可为未来深空探测任务提供技术支持.
The Radioisotope Power System(RPS)is one of the indispensable energy systems for future deep space exploration missions.There are significant differences in the geometric dimensions,struc-tural design,and power ranges of in-service RPSs,leading to low modeling efficiency and difficulties in modeling.Therefore,a digital mock-up modeling and simulation technology for RPS is proposed.Its functions and research methodology were summarized and synthesized.Then,the process,meth-ods,and instructions for thermoelectric coupling analysis and radiation dose analysis in reverse engi-neering of in-service RPS were explained in detail.This technology were applied to the reverse engi-neering of typical RPSs such as the GPHS-RTG,"Chang'e-4"RTG,and MMRTG.Important results were obtained,including the thermoelectric performance,application schemes,and radiation dose distributions of these RPSs under deep-space and planetary-surface environments.The findings dem-onstrate the feasibility and general applicability of the technology,which can provide technical sup-port for future deep-space exploration missions.
