针对人体穿着航天服处于过热状态下的散热问题,在分别建立人体热调节系统、金属氢化物冷源和液冷服数学模型的基础上,将3个模型进行结合,对舱外航天服热控系统在5.5h的时间轴上进行综合的仿真计算,求出人体各节段的温度分布情况,液冷服的入口及出口水温,金属氢化物冷源的出口水温等参数,分析航天员的热舒适性,对航天服热控系统的设计有一定的指导作用,并为今后进一步的研究打下了基础.
Aiming at the problem of human body wearing spacesuit in overheated condition, three models are combined on the basis of establishing human thermal regulation system, metal hydride cold source and liquid cooling service mathematical model respectively, The system performs a comprehensive simulation calculation on the time axis of 5.5h, obtains the temperature distribution of each segment of the human body, the inlet and outlet water temperature of the liquid-cooled clothes, the outlet water temperature of the metal hydride cold source, and analyzes the heat of the astronauts Comfort, the spacesuit thermal control system design has a certain guiding role, and laid the foundation for further research.
