目的计算代谢率为300 W和600 W情况下登月服的热性能。方法在考虑登月服外表面与太阳、月球、登月舱等的辐射换热,登月服内表面与人体之间的导热、对流、和辐射换热的基础上,建立了登月服换热模型;采用编程的方法进行计算。结果得到了代谢率为300 W和600 W情况下人体不同部位的皮肤温度和相关处通风气体和冷却液体的温度。结论在最冷和最热两种极限环境状态下,在登月服的上臂始端、躯干始端、大腿始端设置温度控制器,才能保证人体月面活动的热舒适。
Objective To calculate the thermal performance of lunar suits under the conditions of 300 W and 600 W metabolic rate. Methods Considering the radiative heat transfer between the outer surface of lunar sunday and the sun, the moon and the lunar module and the heat transfer, convection and radiation heat exchange between the inner surface of the lunar surface and the human body, Thermal model; using programming method to calculate. Results The skin temperature at different parts of the human body at 300 W and 600 W metabolic rates and the temperature of the ventilation and cooling fluids at the relevant place were obtained. Conclusion In the coldest and hottest two extreme environments, the temperature controller is installed on the beginning of upper arm, the beginning of trunk and the thigh of lunar landing to ensure the thermal comfort of human lunar activity.
